That Boutique-y Whisky Company launched a five-bottle limited edition collection of single-cask whiskies, featuring expressions aged between nine and 33 years with a 45.8% ABV bottling strength. The set includes single malts from Islay, Speyside and the Highlands, an Irish single malt from Bushmills and a 33-year-old single grain from the closed Dumbarton Distillery, selected from over 300 samples.
Selections were led by TBWC’s head of whisky Sam Simmons and global brand ambassador Dave Worthington and include distinctive finishes such as Pedro Ximénez sherry and ex-American rye barrels, plus a refill hogshead for the 1992 Dumbarton grain. Bottle runs range from 198 to 438 units and each release is presented in 700 ml format and sold via Master of Malt.
For collectors and curious drinkers this set highlights provenance-driven cask diversity and older-grain rarity, offering tasting contrast across regions and maturations. The modest 45.8% proof nods to historical UK standards while aiming to keep flavour and balance accessible for tasting occasions.
