The FDA has proposed regulations for the next year that would require restaurants to list nutritional information for all beers served. To comply with this regulation, craft breweries must order $600 lab tests per beer and the process can take weeks. Dave Lopez, of Gun Hill Brewing, has over 42 different types of beer that would have to be tested. He says the only way to comply with this regulation is to limit the amount of beers available to customers.
