Here are some basic tips for bottling and aging your wine at home. First, a cool environment for storing wines would be ideal because it reduces the effects that oxidation will have on the wine. This is the main reason why you need cool temperatures to store your wines, and why many experts in how to make wine from the home recommend that you store your bottled wine completely out of direct sunlight. You may have noticed that even commercial wineries often store bottled wine in dark cellars or basements. This lessens the incidences of oxygen production in the bottled wine that could alter the taste, often for the worst.
Follow this important rule but don’t get too worried about simple changes in the temperatures where your wine is being stored. A few degrees higher or lower in the temperature scale will have minute effects on your bottled wine that would not be discernible. But, when learning how to make wine from home, it is important to prepare a storage area in advance so that you are not wasting time fretting around for a cool place to store your wine.
It should be quite obvious to you that temperature fluctuations can really be harmful to your bottled wine. This means that a room with a 65 degrees Fahrenheit stable temperature is always preferable to a room whose temperatures are indeed cooler than 65 degrees but will fluctuate from 65 down to 50 then back up again to 65.
Insane temperature fluctuations like this are a challenge for the home wine maker because often it is difficult to find storage at home where cooler temperatures can be controlled to a stable range. Therefore, it is important when undertaking how to make homemade wine that will be good to taste, to prepare the storage area in advance.
Rapid changes in temperature will change the flavors quite significantly. The aromas will wear down, the wine will taste bland, and maybe your bottled wine will lose that character you were seeking for that bottled wine variant. Though your bottled wine may be able to put up with one night of temperature fluctuations, when the temperature flux occurs over a longer period, the stored bottled wine will eventually wear down under these kind of stresses.
When the temperature rises, the wine itself will expand and so in turn, will the wine bottle itself. You will not notice this change because the wine bottle will not balloon out of phase. But natural physics tells us they both will indeed react this way to higher temperatures. When temperature falls, the wine and bottle will then contract. The wine does not expand and contract at the same rate as the bottle though they are subjected to the same temperature in the room. The wine itself tends to expand and contract more than the bottle it is in.
