A beer subscription would be perfect for a 21-year-old man.
From the company: We offer 3, 6, and 12-beer release subscriptions, as well as ongoing subscriptions. We use the term beer release instead of month because perfecting/fermenting beers can take a while and they generally do not come out on a monthly schedule. All beers included in the subscription are beers submitted through our crowdsourced monthly vote.
