Owned by Atom Brands, That Boutique-Y Whisky company is an independent bottler easily identified by its detailed cartoon-style labels. Although the designs are light-hearted, the spirits are meticulously and very often surprising.

Reference Series III is a blended malt bottled by Atom Supplies, the owner of the online store Master of Malt and the independent bottler That Boutique-Y Whisky Company. Every bottling in the range uses the same ingredients but in different proportions: a young blended malt, a richer blended malt, an old single malt and a very old single malt. Each edition is then finished in a special cask, coloured artificially (E150D) or includes peated whisky.
