Innis & Gunn is a Scottish craft beer brand founded in 2003, with its brewery home based in Perth, Scotland. The brand was born out of a happy accident when a well-known whisky producer needed help conditioning its casks — a process that led to the discovery of oak-aged beer and ultimately gave Innis & Gunn its defining identity. From those origins, the brand grew into one of the most recognised craft brewers in the United Kingdom. Innis & Gunn is best known for its oak-aged beers, a signature approach that sets it apart in the craft beer landscape. The Perth brewery serves as the brand's hub for innovation and barrel-ageing, where the team experiments with different cask types and maturation techniques to create beers with distinctive depth and complexity. The portfolio includes the flagship 'The Original', a classic oak-aged beer, alongside Innis & Gunn Lager Beer and a range of other styles. The brand has built a strong international reputation, becoming the number two craft brewer in the UK off-trade, the number one imported craft beer in Canada, and number two in Sweden. 'The Original' and the Innis & Gunn Lager Beer have both received recognition from the Great Taste Awards. In 2024, the brand was acquired by C&C Group, the Dublin-based company behind Tennent's Lager, following a period of administration.
