The Glenfiddich IPA Experiment is a pioneering single malt Scotch whisky finished in custom India Pale Ale (IPA) craft beer casks, resulting in a vibrant, zesty, and hoppy flavor profile. Launched in 2016 as the first in Glenfiddich's "Experimental Series," it combines traditional Speyside malt with the hoppy characteristics of a bespoke, locally produced craft beer, showcasing a collaboration between Malt Master Brian Kinsman and brewer Seb Jones.

The Arran Single Malt selected for this cask strength expression was initially matured in first-fill ex-Bourbon barrels for 7 years before being transferred for secondary maturation into smaller Quarter casks also made of the finest American oak for a further 2 years. The process of transferring our whisky into the smaller 125 litre sized casks for their final 2 years of maturation produces far greater contact between the whisky & oak and a faster, more intense maturation. The end result is a full-bodied expression of Arran Single Malt combining power and finesse full of rich vanilla sweetness and bold peppery spice. Bottling at natural Cask Strength without chill-filtration or artificial colouring of any sort presents this whisky in its purest form. Small casks would have been a common feature of the Arran whisky trade in the eighteenth & nineteenth centuries as they were easier to handle and transport around the island. With our much-loved Quarter Cask expression we proudly bring this tradition back to life.
