Drinking Age and Alcohol Laws for All 50 States
http://www.youthrights.org/dastatelist.php

No one under the age of 21 is allowed to consume or posses alcohol. But interestingly you can taste (can't consume) an alcoholic beverage if it is required of a class in a postsecondary educational institution (college) but only if you're at least 18 years of age. It's illegal to drive a motor vehicle with a BAC of .02 or higher if under the age of 21. For anyone 21 years of age or older may not drive if they have a BAC of .08 or higher
