The alcohol purchase age in the Commonwealth is 21. No one is permitted to serve alcohol to a person under 21 years of age. No one is allowed to possess, drink, transport or purchase alcohol if they are under 21. No open containers of alcohol are allowed in most public areas e.g. sidewalks and parks, even for people of legal drinking age. Massachusetts, more than any other state in the union, vigorously enforces both "Blue Laws" and the drinking age. Most bars, pubs, and nightclubs in Boston have a city mandated 21+ policy, which is vigorously enforced. Additionally, many establishments in Boston and Cape Cod will not serve to out of state visitors under 25. Get a Liquor ID, a state ID card available to non-residents from the Registry of Motor Vehicles if you'll be in the area for awhile, costs $25 for five years of validity. Note that under Massachusetts law, the only acceptable proofs of age for purchase of alcoholic beverages are the Massachusetts driver's license and the RMV Liquor ID card. Out-of-state driver's licenses, and even passports, are not acceptable.
A controversial "third party liability" precedent has been set in Massachusetts. For example, a landlord rents an apartment to young adults who have a party and a person drinks and drives and causes an accident. Under this "third party liability," the landlord, those who hosted the party, and the one who drinks and drives can be held responsible. Rule of thumb for anyone drinking is to not drink and drive; second, if you are under 21 and want to drink in Massachusetts, you're out of luck unless you're at a private party.
Traditional New England culture back to Pilgrims and Puritans was far from abstenious. Surprising amounts of beer, wine, hard cider and distilled spirits were consumed. Although "Blue Laws" once prohibited alcohol purchases on Sundays, alcohol remains central to socializing in both urban and rural settings.
Microbreweries and brewpubs are becoming more common in urban areas and college towns. They usually offer sandwiches and other casual fare as well as a selection of brews that can be far superior to the megabreweries'.
