From the RI General Laws, here are the exemptions to the restaurants rules -

21-27-6. Businesses exempt.

The provisions of this chapter shall not apply to those activities of food business which are licensed and regulated in accordance with the provisions of this title; provided, that retail food businesses and food vending machines limited solely to selling or dispensing ice and/or non-perishable foods, including, but not limited to, gumballs, unopened bottled or canned beverages, and prepackaged candy, nuts, gum, popcorn, chips, pretzels, cookies, and crackers. Honey producers who are registered with the state are exempt from the provisions of this chapter.

Note how it says UNOPENED bottles and cans.

It doesn’t say anything about where the food is prepared, just where it is served and consumed. Breweries, like every place that sells alcohol for on premise consumption, is considered under the umbrella of “restaurant” by the department of health. Same with drinks being considered a food product
