The Food and Drug Administration (FDA) will require that restaurants with 20 or more units include nutritional information facts for beer (and other menu items) beginning may 5th, 2017. This means that chain restaurants with 20 or more units will be asking brewers who supply beer to submit this information.
To help craft brewers meet this new requirement, the Brewers Association has developed a Beer Nutrient Database which reflects the average nutritional value of nine lesser nutrients (total fat, calories from fat, saturated fat, trans fat, cholesterol, sodium, dietary fiber, sugars, and protein). This database, which currently has 41 styles as defined by the BA Beer Style Guidelines, will expand over time as more analytical testing is conducted.
More information on using this database and the FDA requirements can be found on the BA website here.
