The competition, which is mainly dominated by North American breweries saw innis and Gunn win a gold and bronze medal for two seperate beers.
Innis & Gunn were the only Scottish brewer to win an award, and defined their category with two wins in Wood/Barrel Aged Dark Beer, beating domestic brews in the process.
Their Bourbon Cask Dark beer won a gold medal while their Innis and Gunn Aged took home a bronze.
Dougal Gunn Sharp, Master Brewer and Founder of Innis & Gunn said:“We are immensely pleased to have won these awards for two of our most exciting brews. I
“It was a highly competitive category and that makes these wins even sweeter.
“We feel these accolades vindicate our mission to push the boundaries of what beer can be.
“We also want to be seen as great ambassadors for Scottish innovation, what better way to do that than come first in an American beer championship.
“Our Bourbon Cask Dark Ale was initially intended to be a limited edition, but it proved so popular that we’ll be adding it to our year-round core range in the near future.”
Last year, the company, who have their headquarters in Edinburgh, sold over 20 million bottles of beer making it one of the most popular craft beers in the UK.
