How many grams of sugar and carbs in a gin martini?

Answer 1

All sugars are carbs, but not all carbs are sugars (starch is a carbohydrate but it's not a "sugar", even though it breaks down to sugar in your digestive system; cellulose is chemically a carbohydrate but it doesn't break down in your digestive system, so from a dietary standpoint it's considered "fiber"). There are essentially none of either in gin, so the amount in a gin martini depends on how much vermouth you use (and whether or not you put in an olive ... there are some carbs in an olive).
