Dear Dr. Vinny,
Should I store my wine in the fridge if it has a screwcap?
No, that’s not necessary (unless you’d like to keep that bottle of wine chilled to enjoy at fridge temperature). There is no special storage requirement for screwcapped wine.
Screwcaps are an increasingly popular closure for wine, and it’s no longer just for the inexpensive stuff. This closure not only avoids the fuss of crumbly corks and premature oxidation, but screwcapped wines are actually a little more user-friendly. Wines bottled under cork need some extra care—those bottles need to be stored on their sides to keep the corks from drying out, humidity has to be managed, and you need a special tool to open a bottle. Corks are also the most common cause of cork-tainted, or "corked," bottles of wine, in which the chemical compound 2,4,6-trichloroanisole (TCA) can cause musty and damp notes. That's not a concern with screwcaps.
It’s also handy to have a screwcapped wine in the event that you didn’t finish an entire bottle and want to save the leftovers. In that case, I’d recommend sticking the remaining wine in the fridge—no matter if it’s red or white—keeping it cool means you might get some extra life out of it before it starts to fade.
Even though I’m a fan of screwcaps, I don’t select a wine (or not) because of its closure. I understand that some winemakers prefer to stick to cork, and that’s fine with me, even though corked wines are a huge bummer.
