The brewery began life on a farm in Royal Deeside, Aberdeenshire with a student loan. The first beer produced was Armageddon, which the company claimed in press releases was the world's strongest beer at 65% alcohol by volume. Some batches of the beer were incorrectly manufactured to a strength of 15.2% ABV.
In 2013, Brewmeister replaced Armageddon with a stronger beer called Snake Venom claiming 67.5% ABV, and put a warning label on the bottle advising consumers to only drink one per sitting. It retailed at £50 for a 275ml bottle. Brewmeister claimed that the beer "tastes like a liquor and has a whole host of different flavours, ranging from bubblegum to caramel." However, Guinness Book of Records still consider the strongest beer ever sold the Brewdog's "The End of History" with 55% ABV.
In March 2014, the company announced they would move to new facilities at the Isla Bank Mills in Keith and quadruple beer production while in May of the same year, the company won the BQ Scottish Business Award for Export. Richard Lochhead, member of Scottish Parliament for Keith, said that the move would be "a successful addition to Moray's strong food and drinks sector." The brewery currently employs 13 people.
