Reinvent Single Barrel Whisk(e)y with iStill!
20 February 2019
What is single barrel whisk(e)y?
"Single barrel whiskey (or single cask whiskey) is a premium class of whiskey in which each bottle comes from an individual aging barrel, instead of coming from blending together the contents of various barrels to provide uniformity of color and taste. Even whiskeys that are not blends may be combined from more than one batch, or even from differing years to achieve consistency. The whiskey from each barrel is bottled separately, with each bottle bearing the barrel number and in most cases the dates for the beginning and end of aging. Each barrel is believed to contribute unique characteristics to the finished whiskey." Source: Wikipedia.
In short, single barrel whisk(e)y are bottles that come from one unique barrel, instead of from a blend of various casks. Single barrel whisk(e)y making is done in both North America and Scotland, and the producers aim to create an (ultra) premium whisk(e)y class.
