The alchololic drinks without carbs that I know of are gin and rum.
Red wine is just 1g of carb per glass.
Drinks like WKD are overloaded with 35 or 47 g per bottle.
Cider ranges from 15g for dry cider, sweet cider is 25g and vintage cider is 42g per pint.
Hope that helps, hope you enjoy your 18th.
Alchohol best taken in moderation!!! Especially if you havent sampled it in party celebrations before. My worst memory of an 18th party I went to was my friend who got absolutely drunk and ended up wettigherself under the table!! That was 30 years ago... And thankfully in those days it wasnt recorded to go on youtube!!
