How much sugar per teaspoon in 1 oz Pinnacle raspberry vodka?

Answer 1

I'd expect there to be pretty close to none. In most liquor the calories come mainly from the ethanol content, not from sugar (some wines and sweet liqueurs may have significant amounts of sugar, but vodka is generally pretty much neutral spirits plus perhaps a small amount of flavoring).

Incidentally, this is what makes "low-calorie" vodka so hilarious: you could make your own by buying the regular stuff and diluting it with water, because that's exactly what it is. The only way to reduce the calories in vodka is to reduce the alcohol content.
