No More Tart Wine

Wine Acid Testing KitAre you a winemaker who loves to make wine with fresh fruits? If you are, here is one of my quick and easy wine making tips for you. The simplest thing you can do to make your wines better is to start using an Acid Test Kit.

By taking acid level readings of your wine or wine must with an Acid Test Kit you can get the tartness of your wines perfect instead of just close.

This fruit acids along with any Acid Blend you might add to your wine recipes are what control how tart or flat your wines will taste. Too much, and your wines can be enough to give you heartburn. Not enough, and your wines can taste lifeless.

Wine recipes can generally tell you how much Acid Blend to add along with the fruit to get the wine to an acceptable range of acidity — one that’s in balance. But the reality is, fruits vary in the amount of acid they bring to a wine. How acidic the fruit is can vary based on the growing season, variety, etc. By testing the acid that the fruit is actually providing, you can know exactly how much Acid Blend to add to make up any difference.

Using an Acid Test Kit is relatively simple. You take a small sample of the wine or wine must and add a couple of drops of an activator solution to it. Then you add a second solution, known as the Reagent. You keep adding the Reagent until the wine sample changes color. By measuring how much Reagent it took to change the wine’s color, you can determine exactly how much acid is in your wine recipes.

The Acid Test Kit comes with these two solutions along with a glass test tube and a measuring syringe. So, you’ll have everything you need to do the test. But more importantly, the Acid Test Kit comes with complete directions. It also has a chart that tells you what range of acidity your wine should be in for great balance. The directions also tell you how much Acid Blend you need to add to the wine or wine must to get from point ‘A’ to point ‘B’. All the guesswork has been removed.

  1. I have tried numerous times to check the acid level and find it extremly difficult to see the change in color in the whites. any suggestions?

  2. Nancy, I understand exactly what you are saying. Watch for the next blog post that I am currently working — hopefully sometime on Monday, Aug. 20th. It will go over some tips that should help you.

  3. Bob, I am assuming you are referring to a Steam Juicer. Yes, you can use juice extracted from a Steam Juicer to make wine. But, it is important that you weight the fruit used in the Steam Juicer. This is because any wine recipe you will run across will refer to the fruit in pound on by volume of juice. We have more information on using a Steam Juicer on the blog site. Just type in Steam Juicer in the search field on the left of this page.

  4. I started by wine in juice form last October and now almost a year later it has a bit to it. I in my third year and done the same each time and this year I think the wine is not good help

  5. Victor, there are a lot of things that can cause a bite in a wine: leaving the pulp in the fermentation too long, too much acid in the wine, leaving the wine on the sediment too long. These are the three big ones. It depends on you mean by ‘bite’.
