Sweet Idea! Adding Fruit To Wine Kits

Adding Fruit To Wine KitsWe did a Chardonnay wine kit recently. The results were very good, by all accounts. What is your position on mixing peach, apricot or even persimmon into a batch of that? Wondering. Thanks in advance for your time.

Hello Jeff,

Adding fruit to wine kits is a great way to enhance any attractive characteristics that a particular grape may possess. For example: raspberries with Merlot grapes, strawberries with Zinfandel, pears with Pinot Grigio… The options are endless and there is always room for experimentation. It’s a great way to have even more fun while making these wines.

Usually when a home winemaker wants to make a wine in this style, they will mix the wine kit and fruits together in the fermenter and proceed with the fermentation from there. After the primary fermentation has completed, the fruit is then removed as the wine goes into a secondary fermenter. However there is another – more professional – way for adding fruit to wine kits. One that will give you much better control over the end product. In other words, less chance of messing up.

Shop Niagara Mist Wine KitsInstead of mixing the grape concentrate and fruit together at the beginning of fermentation, make the chosen fruit into its own wine, separately.

In the case of your Chardonnay, you could make some peach wine – one or two gallons of it. When it is time to bottle, you can experiment with blending some or all of the peach wine with it.

How much peach flavor you add is a matter of personal taste. You can add a little or a lot. You could do sample taste-testings with varying ratios of the two wines. This is the real power of making the two wines separately. You have complete control over the outcome. If you had added some fruit like peaches at the beginning of fermentation, all you could do is guess as to how much peach to add and hope for the best.

By adding fruit to wine kits in this way, you will have total control over how much fruit flavor is in the wine. This method will also allow you to safely mix blending samples together without risking your entire batch.

We have more information about blending wines together in an article on our website that you may want to take a look at: Blending To Improve Homemade Wines. This article should give you some better insights as to what you are look for when putting two wines together.

As far as whether to try peach, apricot or persimmon, all I can say is that I have seen the most success using peach verses apricot and I have never tasted persimmon added to a Chardonnay. But having said this, I would never tell you not to try any combination. There are no wrong answer when adding fruit to wine kits. Home wine making is about being creative, experimenting and seeing what you can come up.Shop Fruit Wine Bases

My Homemade Wine Is Too Dry. Is There Anything I Can Do?

Zach Galifianakis who's homemade wine is too dry.I have a mustang grape wine that has been aging in a carboy. Last night I tried and it has a hydrometer reading of .992. When I tasted the wine, it was too dry for me. How can I sweeten up this wine to a semi sweet?

Hello John,

One of the great things about making your own wine is that you get to drink it the way you want to – even if you want to drink it like our buddy Zach Galifianakis does. For me personally, this is the fun part of making homemade wine. Adjust it until you get the wine just the way you like it. This is something that can’t practically be done unless you are making the wine yourself. This is what makes this hobby so valuable.

In your case, you are not particularly happy with one of the basic features of the wine: the dryness or sweetness of the wine. You are saying that your homemade wine is too dry for your own personal taste. Fortunately, the solution is very simple. All you need to do is add sugar to the wine until it is at the sweetness you desire – custom made for you!Shop Wine Conditioner

It is important to remember that you do not want to adjust the sweetness of a wine until it has completely cleared up and is ready to bottle, so make sure the wine is ready to be bottled before adding the sugar.

At bottling time you can make the wine sweeter tasting. One of the easiest ways of doing this is to use Wine Conditioner. This is basically a sweetener and stabilizer combined together into a syrup. The stabilizer (potassium sorbate) makes sure that your wine does not start fermenting the new sugars while in the wine bottle.

You can also use your own sugar, honey, etc. to sweeten your wine, but you will also need to add potassium sorbate separately to eliminate any chance of the wine re-fermentating. So, as I think you can start to see, if your homemade wine is too dry, it’s not that big of a deal to fix.

If the sugar you are using is granulated, I would also suggest that you pre-dissolve the sugar into a syrup before adding it to the wine. This will help to eliminate the need for excessive stirring when adding the sugar.Shop Potassium Sorbate

When actually sweetening your wine it is best to sweeten a portion of the batch, first. For example, take a measured sample of the wine – say, one gallon – and add measured amounts of sweetener to it to establish a dosage to your liking. Once the dosage is determined you can then do the same thing to the rest of the wine. This insures that you do not get the entire batch too sweet.

If you do accidentally add too much sugar to the measured sample, just blend it back into the rest of the batch and start all over with a new gallon sample.

We also have an article on our website, Making Sweet Wines, that will have more information about what to do if your homemade wine is too dry. You may want to take a look at it as well.

What Size Rubber Stopper Fits What?

Rubber Stopper That Is The Right SizeOne of things that almost every home winemaker uses is a rubber stopper. It’s used to attach an airlock to a plastic fermenter or wine carboy. The rubber stopper is tapered in shape, has a whole in it for the airlock, and comes in various sizes.

Knowing what size of rubber stopper to purchase can be of some issue. Whether you are using a gallon glass carboy or plastic fermenter makes a difference as to the size rubber stopper you need. I thought it would be nice to go over, “what size rubber stopper fits what”, since we offer 25 different sizes to choose from.

I should start of by saying that any bucket fermenter we offer takes a size #2 rubber stopper. This may not be the case with a fermenter purchased elsewhere. It depends on the size of whole the supplier decides to put into the plastic fermenter.

Glass carboys come in an array of sizes and take a different sized rubber stopper as the size changes. There are 6.5 , 6 , 5 and 3 gallon sizes. The rubber stopper size for each is as follows:

6.5 Gal. Glass Carboys (Size #6.5) Shop Carboys
6.0 Gal. Glass Carboys (Size #6.5)
5.0 Gal. Glass Carboys (Size #7)
3.0 Gal. Glass Carboys (Size #7)

7.0 Gal. Fermonster Large-Mouth (Size #10)
6.0 Gal. Fermonster Large-Mouth (Size #10)

You may need to size a plastic wine carboy with a rubber stopper as these have become more popular over time. A plastic carboy takes a size #10.0 rubber stopper regardless of its size.

Other sizes of rubber stopper you may need to know is are:

Wine Bottle Opening (Size #2.0)
Beer Bottle Opening (Size #2.0)
Large-Mouth Gallon Glass Jugs, Quick Quarter Turn Lid (Size #8.0)
Small-Mouth Gallon Glass Jugs, Thread-Down Lid (Size #6.0) Shop Wine Airlocks

Darn It! My Wine Smells Like Rotten Eggs

Homemade WineFor the first time ever I ordered juice concentrate, your merlot and blackberry, to try making a large batch of my favorite flavors. Well, I followed the directions to the letter and it all fermented nicely in the primary. After 5 days racked it to the secondary, 6 gallon glass carboy but for the first time left a little head space of a couple inches figuring that it would be ok since it it was still bubbling a little. It has been two weeks and I racked it again to get it off the sediment and OMG it smells of sulfur, or rotten eggs! Once the wine was in my plastic bucket the smell dissipated and the wine tasted ok but today I checked it and there is still a smell. What did I do wrong? I’ve heard of adding egg white to try to take away the smell…. what can I do? I really hope I don’t have to dump it. HELP!

Hello JoAnn,

All fermentations put off some sulfur or rotten egg smells. Some much more than others. When a wine smells like rotten eggs, what you are actually smelling is hydrogen sulfide. There are many of reasons why one fermentation might produce more hydrogen sulfite than others, but here are the big four:

 

  1. Fermenting With Wild Yeast: Shop Wine Yeast
    In your case, we can rule this out because you are using a wine ingredient kit that comes with a domesticated wine yeast. But if you were relying on wild yeast to do your bidding, this would most likely be the reason why your wine smells like rotten eggs. Some wild yeast can produce tremendous amounts of hydrogen sulfide.
  1. Lack Of Nutrients:
    Not having enough nutrients in the fermentation is another cause of high hydrogen sulfide output. But again, you are using a wine ingredient kit that has been nutritionally balanced. The yeast nutrient is at its ideal level in the wine concentrate, so we can also rule this out for your particular situation.
  1. Fermenting At Too Warm Of Temperature:
    Fermenting your wine too warm is another common reason for a fermentation to produce and abundance of hydrogen sulfide. Temperatures that are above 75°F. are suspect, and anything over 80°F. are likely to be problematic to some degree.
  1. Overworked Yeast: Shop Yeast Nutrients
    This happens when there is too little wine yeast to do too much job. There have been many times when a winemaker will accidentally kill a significant portion of the wine yeast when rehydrating it in warm water. If the wine yeast is put in rehydrating water that is too hot, or the yeast is left in the water for too long, more yeast cells will be killed than anticipated by the wine yeast producer. This sets the stage for a fermentation with too little yeast, and in turn, produces too much hydrogen sulfide.

 

The Overall Theme:
It is important to point out that all the above reasons relate to allowing the yeast to ferment under stress. When a wine smells like rotten eggs, start look at thing that might be putting fermentation in a stressful situation.

Having a wild yeast that is fermenting out of its normal element is stressful; having any yeast ferment with a shortage of nutrients, or ferment in a temperature range that is uncomfortable to it is stressful; and having a little bit of wine yeast doing a lot of work are all stressful things that will lead to high hydrogen sulfide production. Having said this, the whole idea is to keep the wine yeast happy and you will keep the hydrogen sulfide production down. Shop Potassium Bisulfite

 

What To Do Now:

— Give It Time: A lot of the hydrogen sulfide will release and dissipate on its own. It sounds like this may be the case with your wine currently. And, more will dissipate when you bottle the wine.

— Add Sufites: Also, adding a dose of sulfite to the wine will help to drive out the hydrogen sulfide. You can add the sulfite in the form of Campden tablets, sodium metabisulfite or potassium metabisulfite. Just following the directions that are on the package and let the wine sit for a few days.

— Use Copper: If the wine still smells like rotten eggs, you can pour the wine through a copper scouring pad. When the wine comes into contact with copper a reaction will occur the encourages the hydrogen sulfide to release as fumes. The reaction will cause the copper to corrode, so your may need to use more than on copper pad.

My Homemade Wine Has Bubbles And Sediment. What Should I Do?

 

Wine GrapesI made 36 gallons of wine last year, a Alicante and Zinfandel mix. This was my first attempt at winemaking. I followed the instructions from a winemaking book. I racked the wine three times put in the proper extra ingredients then bottled it over the correct period of time. The wine turned out terrible. There is still sediment and it must have not fermented properly because the wine still has bubbles. Is there anything that I can do? I’m thinking of emptying all the bottles into my 35 gallon container. Maybe letting it set and rack it again. I don’t know what to do because it really doesn’t taste good at all. Any suggestions would be really appreciated. Even throw it all out!
Thanks Frank

Hello Frank,

Most of the time when I hear about bubbles and sediment in the wine it’s because the wine is still fermenting in the bottle. The fermentation causes CO2 (carbonation) to form in the wine and sediment to drop out (dead yeast cells). But, in this cause I am also concerned about the wine having spoiled, as well.

Shop Degassing PaddlesSpoilage is best determined by the wine’s smell. Does it have a fingernail polish or paint thinner odor? Does it have a cooked cabbage or rotten food odor? Do you smell something like rubber or band-aids in the wine? Any of these would indicate potential spoilage. The only smell that would be acceptable, other than the fresh bouquet of the wine, would be a sulfur or yeasty smell. This would be expected from a freshly fermented wine and will lessen with time.

If it seems that the wine has spoiled, there is little you can do about it other than to discard it. There is nothing you can do to reverse such a wine fault. But, if the wine is not giving off any of these off-odors, then there is hope.

From you description you gave of bubbles and sediment in the wine, it may be very likely that your wine is still slightly fermenting or has fermented in the bottles. If this is the case – then just as you have suggested – decanting all the bottles of wine back into a fermenter would be the first plan of action. Try not to splash the wine anymore than necessary. This can cause the wine to oxidize.

The whole idea behind putting the wine back into a fermenter is to allow it time to finish fermenting, if necessary, and/or to clear up. Take a hydrometer reading of the wine. If the Specific Gravity is above .998, then some fermentation time is needed.Shop Bentonite

Once any fermentation is done, you will want to degas the wine. This is done simply by agitating the wine so as to release all the CO2 gas from the wine. You can use a tool call degassing paddle to help degas your wine as well.

The wine will need some time to clear. This is something that can only begin to happen after any fermenting has completed. A fining agent such as bentonite may be added to help speed up the settling process. Being patient with this step will be in the wines favor. Just keep it under air-lock and give it plenty of time, even months. There is nothing wrong with bulk aging a wine. If you do plan on waiting more than a couple of weeks to bottle the wine, you should add a half-dose of potassium metabisulfite to the wine. (1 teaspoon to every 32 gallons).

When the wine is ready to be bottled, you will want to siphon it off the sediment, first. You will also want to add another full-dose of potassium metabisulfite right before bottling. Shop Potassium Bisulfite

2 Great Questions About Bottling Homemade Wine.

Screw-Cap-Wine-Bottle1. Are the mushroom cork or t-corks easy to install, or do you need special equipment. Do they seal as well as regular wine corks, (over time)?

2. Wine bottles that have a screw top, can you reuse them with a wine cork?

Name: Tom H.
State: Davison, MI

Hello Tom,

The T-corks (mushroom corks) are very easy to install. This is the biggest advantage to using them over traditional wine bottle corks. You do not need a wine bottle corker or any mechanism of any kind. You simply put T-corks in by hand. Every now and then you may get a stubborn one, but that can easy be remedied by tapping on it with a rubber mallet or similar.

The biggest disadvantage with T-corks is that they are not meant for long-term storage. Some wines made from fresh grapes or maybe elderberries may require several years of aging. These are not the corks to use for that situation. We recommend using T-corks for wines that you intend to drink within a one to two years.

Shop T-CorksAs to your second question about using wine bottle corks on a screw-cap wine bottle, the answer is “not advisable”. This is for two reasons. The first is that the size of the opening of the wine bottle is critical to the success of the wine bottle cork. The wine bottling opening needs to be 3/4″. This is not the case with most screw-cap wine bottles. They are all close, but usually off a bit.

The second reason, and the one that is most important, is the shape of some screw-cap wine bottles are not correct to accept a wine bottle cork. The opening of the wine bottle needs to be a straight barrel. With some screw-cap wine bottles the barrel is not straight. The shoulder of the wine bottle rises too high to accommodate a straight barrel opening that a wine bottle cork needs, so what you end up with is a slightly-flared barrel opening.

Without this straight-barrel opening two things can happen:

 

  1. The cork does not seal tightly enough along the whole length of its side. As the barrel opening flares out, the resistance against the side of the cork becomes less and less.
  1. Because of this flaring and uneven resistance, it can actually entice the wine cork stopper to pull down into the bottle. I’ve seen this happen more than once. Think of squeezing a marble between your fingers. If you don’t squeeze it evenly or to one side, it pops out. This is the same effect that can happen when corking a screw-cap bottle that has a flared barrel.

 

Thanks for the great questions, Tom.Shop Wine Bottle Corkers

Is Wine Yeast And Baking Yeast The Same?

Wine Yeast Not Baking YeastI need you to help me settle a bet with a friend who also makes wine.  He says that wine yeast is no different than what you can get in the store to make bread with.  His quote “yeast is yeast”.  I say that it is different, although I can’t explain how.  Please help settle this and let us know who has to pay up, plus if there is a difference between wine yeast and baking yeast can you explain it to me.

Thanks,
Jamie
———-
Hello Jamie,

I’m going to be brutally honest, here. I hope this doesn’t break-up a good friendship.

To say that yeast is yeast is like saying a dog is a dog. Over the centuries dogs have been bred for various, specific tasks: hunting, herding, personal protection, attacking, protecting herds, companionship, etc. The same can be said for yeast. They have been bred over the decades to perform specific tasks: rising bread, making alcohol, bio-degrading oils, pharmaceutical production, etc.

So to bring this analogy full circle, when you’re making wine with a baking yeast, you’re hunting grizzlies with a chihuahua. Sorry friend, but wine yeast and baking yeast are not the same. In fact, they are very different. I would never recommend making wine with bread or baking yeast.

Shop Yeast NutrientWine yeast in particular is bred to obtain higher alcohol levels than baking yeast. On average, bread yeast will get you 9 or 10%. Anything higher than that is possible, but the baking yeast will have to struggle considerably.

Wine yeast are bred to thrive very well with the set of nutrients fruits naturally provide. Baking yeast, on the other hand, prefers the balance of nutrients found in grains or bread doughs.

Wine yeast clears more quickly from the wine than baking yeast. Wine yeast is bred to clump together as the fermentation activity slows – a process known as flocculation. The clumping allows the wine yeast to drop out and settle to the bottom more quickly. Baking yeast does not clump or flocculate. Instead, it slowly settles to the bottle as a fine haze. This process can take weeks instead of days.

Wine yeast foams less than baking yeast. This is because wine yeast are bred to produce less surface tension in the liquid than baking yeast.

Wine yeast is also more tolerant to sulfites than baking yeast. The wine yeast has actually been acclimated to coexist with some residual sulfites such as Campden tablets in the wine. This means that wine yeast can ferment just fine with some sulfites in the wine must. Baking yeast is not as fortunate. Even small amounts of sulfites can stop a wine fermentation dead in its tracks.Shop Wine Making Kits

Another issue is that bread yeast is only packaged under food-grade conditions. This is certainly suitable for baking. The yeast is only being utilized for a few hours, not days, so the perpetuation of any contaminating organisms do not have enough time to do any damage.

On the other hand, with wine yeast we are talking days if not weeks that the yeast is in play. This is plenty of time for stray organisms riding on the yeast to potentially breed into a full-fledged infestation spoiling the wine. For this reason, wine yeast is package under sterile conditions. This is far more stringent than food-grade packaging.

To sum all this up, you can certainly make wine with a baking yeast, but you will be sacrificing flavor and potentially alcohol. You are also increasing the likelihood of having a stuck fermentation. This is because of issues with nutrients and the use of sodium metabisulfite.

So, as I think you can see, wine yeast and baking yeast are not the same. In fact, there are many differences between the two. That combined with the fact that wine yeast is not all that expensive to buy, why wouldn’t you use it in your winemaking?Shop Wine Yeast

My Wine’s Starting Specific Gravity Is Too High

Starting Specific Gravity Is Too HighHi, I followed a recipe for blueberry wine that called for 15 pounds of sugar and 20 pounds of frozen blueberries for a 6 gallon batch. I just measured it with my wine hydrometer and got a reading of 1.148 ! I know this starting specific gravity is too high. Is there anything I can do other than hope for the best ? I am new to wine making and have no idea ?

Marshall S. – IA

Hello Marshall,

Well, that’s an interesting wine recipe. The starting specific gravity reading you got on your hydrometer, does make since with that much fruit and sugar being added. The bad news is that the odds of a fermentation even starting at that high of a specific gravity reading is very low. When the concentration of sugar gets too high, it starts to act as a preservative, keeping the yeast from fermenting.

The good news is that I think we can fix it. Simply put, your wine’s starting specific gravity is too high, and we need to think about how we can lower it.

Shop Hydrometer JarsIn reality, there are two concerns. The first one is the most obvious: too much sugar for the yeast to start fermenting. That’s what the specific gravity reading is telling – how much sugar. But there is also a concern that there may be too much blueberry – enough to make the wine overly tart and astringent. With that being said, here’s what you can do:

 

  • Dilute the wine must with water until you get a reading of 1.100. If you like, you can use a Pearson square to calculate how much water to add to get from 1.148 to 1.100. (Water has a S.G. of 1.000) There will still be plenty of blueberry flavor to go around. Our blueberry wine recipe only calls for 13 lbs. to 5 gallons, so don’t worry about weakening the wine’s flavor too much. And besides, you really don’t have much choice when your wine’s starting specific gravity is too high. The yeast aren’t even beginning to think about fermenting with that much sugar.
  • Take an acid reading with an acid test kit. This will tell you if the blueberries are still providing enough tartness to make the resulting wine taste right. The directions in the acid test kit will tell you what range you are shooting for. My guess if that you will need to add a little Acid Blend after diluting with water to bring the acidity up a bit. But, if the acid level is still too high, you will want to dilute the wine must with even more water. Just try to keep your wine’s starting specific gravity above 1.075.
  • Once you have the sugar level and acidity in a decent range, it’s all smooth sailing. If you haven’t added add yeast nutrient at this point, I most certainly would, now. The same goes for pectic enzyme, and wine tannin. If you got the ingredients from us, you will find recommend dosages on the side of each container.Shop Acid Test Kit

 

If you have already added the wine yeast you can still do all of the above. The yeast will be fine. If you have not, be sure to use and actual wine yeast. Don’t add a bread yeast.

Once you’ve got the specific gravity and acidity level ironed out, you will continue on like you normally would with any winemaking process. Here’s an wine making infographic that lays out the basic steps for you.

Hope this information helps you out. I urge you to do the above steps. Don’t dump it out. Nothing you have done or will do in the above steps will compromised this wine in any way, so it will be well worth the effort. Believe me, you are not that only one that’s ran into this problem. Many home winemaker’s have gotten their wine’s starting specific gravity too high. Just take things a step at a time and your wine will be out of the woods.

I would like to welcome you to take a look at our wine recipes that are free for anyone to use. These a solid, time-tested wine recipes that will keep you out of trouble in your future wine making adventures.

What Size Corks Should I Get For Bottling My Wine?

Different Size Corks For Bottling WineIf you’re getting ready to buy corks to bottle your wine you may be wondering which size corks you should get. We offer four different sizes of wine cork stopper. They are sizes: #7, #8, #9 and #10. These numbers refer to the diameter of the cork. The higher the number, the larger the diameter of the cork.

The opening of a standard, 750 ml wine bottle is 3/4 of an inch. If you have a wine bottle corker you will want to purchase either the size #8 or size #9 corks. The diameter of these corks are 7/8″ and 15/16″, respectively. Size #9 corks is what the commercial wineries use. Either will require a wine bottle corker to press them into the bottle.

Which size cork you get depends on the type of wine bottle corker you have. Any wine bottle corker on the market can put in the size #8 wine cork, however some wine bottle corkers have trouble putting in a full-size #9 cork.

If the corker was purchased from E. C. Kraus, you will be able to put in a size #9 or #8 cork just fine. If your corker was purchased from somewhere else then some caution will be required.Shop Wine Corks

Some wine bottle corks on the market use a funnel-design to compress the cork. The wine cork is shoved through a funnel into the opening of the wine bottle. For the most part, this design of corker will work okay for a size #8 cork, but if you want to put in a full-size #9 wine cork and get a tighter seal, using a funnel-style corker can be a problem. The larger cork can get pinched and frayed as it goes through the funnel.

All the wine bottle corkers we offer compresses the cork evenly, from all sides then plunges the cork into the barrel opening of the wine bottle. With this method of corking no damage will come to the cork, as it is not be contorted through a funnel opening.

We do not recommend using size #7 cork, but we do offer them for individuals who want to put their corks in by hand. This size wine cork is small enough in diameter to be put in without a wine bottle corker. The downside is that they do not seal the wine bottle very well. In fact, if you lay the wine bottle on its side, there is a fair change that the #7 wine cork will seep some wine. For this reason you should store wine bottle upright if using this size of wine cork.Shop Wine Bottle Corkers

Size #10 corks are for larger size bottles. While many larger bottle still have the same 3/4 inch opening that the 750 ml have, some larger size wine bottles have larger openings that will require this larger size cork.

There’s A Yeasty Smell In My Wine. Should I Dump It!?

Noticing Yeasty Smell In WineI’m still learning this process but haven’t had this happen. Got 3 gallons of Muscadine wine I was gonna bottle up. When opened up it has a very strong “yeasty” smell in the wine. Made this a couple times and never had this happen. Only thing I did different was use a different wine yeast. (Montrachet instead of lavlin 71b 1122.) I may have forgotten to rack the wine after it had been placed in the secondary fermenter. Either forgot to write it in log or didn’t do it. Seems I read somewhere that could cause this issue. Anyway, should I bottle this or dump it and start a new batch when the Muscadines ripen this summer. Thanks for the advice……..

Hello Bill,

There is absolutely no reason to dump any wine because it has a yeasty smell. This is an issue that comes about from time to time that is easily overcome.

It is true that different wine yeast have different amounts of yeast odors, but the yeast smell also increases the more the yeast become stressed. If the fermentation is done in an environment that does not make the wine yeast happy, you will get more of this odor.Shop Wine Yeast

Examples causing stress are:

  • Fermenting at too warm of a temperature
  • Fermenting with not enough nutrients in the wine must
  • Fermenting with too little yeast to perform the job at hand

The last one typically happens with old wine yeast is used, or a significant portion of the yeast cells are killed in the rehydration process.

Most of the time this odor will go away on it’s own throughout the natural course of the winemaking process. Racking the wine is one of the times that this odor is able to release from the wine and dissipate. You stated that you are not sure if you racked the wine, so this could be all that’s wrong with the wine.

Another normal activity in the winemaking process that releases this odor is adding sulfites. This would either be Campden tablets, potassium metabisulfite or sodium metabisulfite. If you do not ever add any of these then this can contribute to the yeasty smell in the wine.

Shop Potassium BisulfiteA sulfite should always be added to a wine anyway to protect it from spoilage and oxidation, but doing so also drives out unwanted volatile gases that are in the wine from the fermentation – such as the ones you are smelling. If you haven’t done so already, the simple task of adding a standard dose of sulfites and waiting a few days may be all that is needed.

Since you are not sure if you racked your wine or not, I’m guess that all you need to do is rack the wine and add sulfites. Hope this should get rid of the yeasty smell in your wine. In not, repeat the process. Rack the wine in a splashing manner and then add sulfites again.

If you find that the yeast smell in the wine is not leaving that you may want to take a look at what to do about treating wine with a hydrogen sulfite issue.

Just remember next time to keep your wine yeast happy, regardless of the type used; rack your wine sufficiently; and always use sulfites in your wine. Do these things and you should not have this problem again.Shop Mini Jet Wine Filter
