The Boston Beer Company is an American brewery founded in 1984 by James "Jim" Koch and Rhonda Kallman.

Since its founding, Boston Beer has started several other brands, and in 2019 completed a merger with Dogfish Head Brewery.

[7] At the time, Koch was working at Boston Consulting Group after receiving BA, MBA and JD degrees from Harvard University.

While serving in his role as a manufacturing consultant at BCG, Koch developed a business plan for a locally focused beer company.

He invested $100,000 of his own money and raised additional funds from investors, family members, and friends including former classmates and BCG colleagues.

[9] Koch named his beer after the Boston patriot Samuel Adams, who fought for American independence, and who also had inherited a brewing tradition from his father.

On August 15, 2002, a Virginia couple was charged with public lewdness after attempting to have sex in a vestibule at St. Patrick's Cathedral; this led to the firing of the radio hosts a week later.

In an interview with the Associated Press the company said it was willing to discuss Adams' use of his name on his Web sites, "probably for the length of the time the election is being held".

[23] The Boston Beer Company stated that they believed fewer than 1% of bottles from the supplier could contain small pieces of glass and issued a recall for the safety of consumers.

[27][28] In 2018, the company pushed for changes to the definition of "craft brewery" in order to accommodate a continuing shift away from beer-only operations toward other brewed products including ciders.

[31] In 2020, Boston Beer Company invested $85 million in its Cincinnati plant to quadruple its canning capacity of Samuel Adams, Angry Orchard, Twisted Tea, and Truly Hard Seltzer.

[33] First brewed in 2014, Samuel Adams Rebel IPA is a West Coast style India pale ale.

[36] The beers in this collection are American Kriek, New World, Stony Brook Red, Thirteenth Hour and Tetravis.

[37] The company followed this up in 2002 with Utopias; at 24% ABV, it was marketed as the strongest commercial beer in the world (a mark that has since been challenged).

"Lambic" describes a spontaneously fermented beer generally produced in Brussels or the nearby Pajottenland region,[41] and the Samuel Adams product is not spontaneously fermented, consumers and brewers charged that "Cranberry Lambic" was mislabeled[42] and could cause consumer confusion.

[43] Grant Wood, Senior Brewing Manager at Boston Beer, defended the name, saying, "I wouldn't consider it mislabeling.

Boston Beer Company launched a line of hard seltzers in 2016 under the brand name Truly Spiked & Sparkling.

[48][49] Boston Beer operates a number of other sub-brands, including The Traveler Brewing Company (which focuses on shandy variants), Coney Island Brewing Company (purchased from Schmaltz Brewery and brewing a nationally available line of hard sodas in addition to beer exclusive to the New York City market), and also owns the Los Angeles-based Angel City Brewery and the Concrete Beach Brewery in Miami.

[51] Approximately 15,000 cases were released in North America in December 2010 at a suggested retail price of $20 per 750 mL bottle,[52] Marketed towards drinkers who would rather toast with beer than Champagne on New Year's Eve, Infinium is described by the brewers as "the first new beer style created under the Reinheitsgebot in over a hundred years".

[54] As of 2015, the company had helped more than 4,000 entrepreneurs and together with their lending partner, Accion, made close to 400 loans totaling $400 million.

[54] In early 2008, amidst a worldwide shortage of hops—a key ingredient in beer—Boston Beer Company agreed to sell 20,000 pounds of its hops, at cost, to craft brewers throughout the United States.

Homebrewers submit their brew to a series of judging and taste tests with the chance to see their creation in larger-scale production and sold on store shelves as part of a Samuel Adams mixed 6-pack the following year.
