As of 2007, the company produces twelve varieties of beer year-round: Boston Lager, Sam Adams Light, Boston Ale, Pale Ale, Cherry Wheat, Cream Stout, Brown Ale, Hefeweizen, Scotch Ale, Black Lager, Honey Porter, and Irish Red.

The Sam Adams Boston Lager contains 4.9% abv, roughly average for its style. Other styles have pushed the physical limits of alcohol content for the brewing process – in 2003 one batch of Utopias contained 25.6% abv, beating the records that Samuel Adams Triple Bock and Samuel Adams Millennium had set before it.

The company brews five seasonal beers per year, as follows:

• White Ale (January – March)
• Double Bock (March- April)
• Summer Ale (April – August)
• Octoberfest (August – November)
  Winter Lager (November – January)
