Dear Dr. Vinny,

I'm a diabetic, so I try to drink the driest wines I can find. Which wines have the least amount of sugar?

—Jim, Milton, Pa.

Dear Jim,

First of all, please talk to your physician about including wine as part of a healthy lifestyle, especially when it comes to sugar. But I can tell you that during fermentation, the sugar in wine grapes is converted to alcohol, which means that wines made in a dry (as opposed to sweet) style don’t have a lot of sugar in them—most are in the ballpark of less than 10 grams per liter of residual sugar.

As far as determining the actual amount of sugar in a bottle of wine, it’s not that easy. Sure, some styles are known for being drier and crisper and, others are richer and fuller-bodied. But there are many variables—like vintage variations, winemaker decisions and house styles—that impact the actual sugar content of wine.
