Hello Mr. Gerchak,

Thanks for the kind words. We try very hard to answer your questions to the best of our ability.

It is perfectly fine, and preferable, that you age your wines for a few months. The need for aging your homemade wine is a given. I have found that with white wines 6 months will get the majority of the aging done. The typical white you find on the store shelf has been aged for about 18 months. Red wines could be aged anywhere from 2 to 5 years before they are sold.

Of coarse, the type of wine grape we are talking about enters into this equation, as well. For example, a Gamay will need much less aging than a Cabernet even though both are red grapes. This is because the make-up of each of these grapes are very different. Most notably, their tannin structure are on opposite ends of the scale – Gamay being low tannin, Cabernet being high tannin. This plays into how much aging is required for a wine to fully maturate and exude the maximum pleasantries that it can.

Just as the type of grape can affect the aging life of a wine, so can temperature, and this leads us back to answering your question about aging homemade wine in a refrigerator. Very simply: the cooler the storage temperature, the slower the wine will age. Although this is the general relationship between temperature and aging wines, there is still a optimal temperature range at which you would like to store your wines. This would be somewhere between 45°F. and 65°F. If you can’t store your homemade wine in this temperature range, then you want to get as close as you can.

Shop Wine Bottle CorkersSlow, cold aging can be either a good thing or a bad thing depending on your perspective. As home winemakers we tend to want our wines to age quickly. We want the time between bottling and consumption to be very short. We want them to be at their best in a matter of weeks, not months or years, for no other reason than we are impatient. On the other hand, aging the wine too quickly could leave you with a rack of wine that has all passed its prime. Wines do not continue to improve indefinitely with more aging.

With that being said, the temperature at which you age your homemade wine should be taken into consideration. partially based on your consumption habits. Your adjustment could be something as simple as storing the wine upstairs instead of downstairs, in the cooler basement or vise versa. Or as you have mentioned, moving the wine from the basement into a refrigerator.

As you may have gathered by now, aging homemade wine in a refrigerator is okay to do, just expect it to take longer to fully mature. If you do not have a problem with this, no worries, however if you are wanting you wines to age as quickly as possible, this may not be the route you want to go.

Temperature Controller For RefrigeratorThere are a couple of suggestions I could make that would help improve upon your desire to refrigerate your wine. One is to age the wine at more-convenient, warmer temperatures for a few month – say, 3 to 6 months. Then store the wine in the refrigerator at its maximum setting (usually around 45°F). This will suspend the life of the wine for many years.

You could also go a whole different route. You could purchase a external, power interrupt temperature controller thermostat. This would allow you to set the refrigerator at any cooler temperature you would like, even 65°F. You do this by setting the refrigerator to its coldest setting. Then use the temperature controller to run the refrigerator as needed. It acts as an external thermostat that turns the power to the refrigerator on and off as need to maintain the temperature you select.

Happy Winemaking,

  1. When you use the term white wine? Are you referring to wine must, that is fermented with out the grape skins during fermentation, such as making it from store bought juices and concentrates? I thought white wine means wines made without the skins?

  2. James, in the context of the above, white wine is referring to any wine that is lighter in body. Lighter boded wines need less aging. This would typically be wines that were not fermented on the skins, but it does not mean all store bought juices and concentrates. Many of these juices are stored with the pulp before being concentrated, so in fact, you can have a full bodied wine from a juice or concentrate.

    • D. Finley, the storage temperature would be the same for fruit wines as well. As far as the aging time, a good rule of thumb for fruit wines is about 6 months.

    • Lalit, it would be fine to store your oak barrel in the refrigerator. However, we would recommend cleaning the inside of the refrigerator with bleach before doing so. This will help prevent contamination of the outside of the barrel with mold or bacteria.
