Decanting a wine, especially in the summer, can present a problem. Typical decanting times are 30 minutes to an hour our more. So, if you’ve been keeping your wine at a cellar temperature of 52-57°F for a red, or slightly chilled to 45℉ and 55℉ for a white, it going to warm up to room temperature during decanting.
Here are a few tips for keep a wine cool during and after decanting:
If you’ve got plenty of time and can plan in advance, go ahead and decant your wine at room temperature and then return it to the original bottle and place it back in the wine refrigerator for an hour or so to return it to the desired temperature
Your decanter should have a wide base to allow for maximum surface area contact of the wine with air, so place a chilled towel or a bag of frozen peas or corn over the base of the decanter to keep the wine chilled. For longer decanting times you may need to change out the towel or add another bag of frozen veggies
If your decanter can fit inside a refrigerator, just beware that it’s possible the wine can take on some ugly refrigerator smells, so check first or ensure you’ve got a fresh box of baking soda in the frige to soak up those nasty smells
If you have one of those freeze sleeves that can fit around a bottle of wine, see if it will simply fit around the neck of your decanter to help keep the decanting wine chilled
So, if decanting your wine, remember that all wines taste best if served at the proper temperature. Therefore, decant when necessary but ensure you serve your wine at its best temperature. Cheers!
