That Boutique-y Whisky Company (TBWC) has unveiled a new limited-edition collection of single cask releases, showcasing the standout casks from over 300 sampled at the end of 2025.

The five new releases, aged between 9 and 33 years and bottled at a deliberate 45.8% ABV, comprise single malts from Islay, Speyside and the Highlands, alongside a single grain from the long-closed Dumbarton Distillery and an Irish single malt from Bushmills.

As with all Boutique-y releases, each expression is non-chill filtered and bottled at natural colour. The labels have been reimagined by long-time collaborator and Glasgow-based artist Emily Chappell, drawing on characters from the original Boutique-y artwork while retaining the brand’s distinctive regional colour palettes.

The new TBWC collection includes:

TBWC 13 Year Old Caol Ila – Islay (RRP: £69.95 | 327 bottles)
A sweet, spicy, and smoky Caol Ila, enhanced by a two-year finish in a fresh ex-American rye barrel. Coastal air and sweet smoke lead into brine and warming spice, while the palate offers a firm oak grip with toasted almond, burnt sugar and savoury charred barbecue notes.

TBWC 9 Year Old Glen Elgin – Speyside (RRP: £49.95 | 438 bottles)
This Glen Elgin spent a period finishing in a PX hogshead, deepening the distillery’s character into dark, sweet spice while retaining the fresh, invigorating ‘sipper’ quality that Glen Elgin is famed for. Bright and notably sweet, with candied orange peel, plump dark raisins, and ripe red apples, the palate reveals runny honey, nuttiness and a subtle touch of fresh lavender, rounded out by sticky toffee pudding richness.

TBWC 27 Year Old Glen Garioch – Highlands (RRP: £199.95 | 198 bottles)
Laid down in a refill sherry butt in 1998, this well-aged classic balances character, wood, and time. Deeply autumnal and ‘warehouse-y’, with polished oak, warmed vinyl, and overripe tropical fruit, the palate is remarkably oily and complex, revealing damp oak, dried figs, aged leather, pipe tobacco and dark chocolate, lifted by flashes of mango and papaya.

TBWC 33 Year Old Dumbarton – Single Grain (RRP: £124.95 | 242 bottles)
Distilled in 1992 at the now-demolished Dumbarton Distillery and matured in a refill hogshead, this rare single grain offers a glimpse into one of Scotland’s lost whisky sites. Sweet cereal and freshly baked shortbread lead into vanilla wafers, while the palate is light and silky, with tropical fruit, coconut and spearmint, finishing on pineapple and cedar.

TBWC 22 Year Old Bushmills – Irish Single Malt (RRP: £249.95 | 390 bottles)
Originally laid down in October 2002 and re-racked in January 2023 into an ex-Maury wine cask for extended finishing, this triple-distilled single malt balances fruit and fortified wine influence over 22 years. Sweet, milky black tea and buttery shortbread give way to mango, milk chocolate, and syrupy sultanas, while the palate coats with creamy caramel, tropical fruit and dark plum, finishing with refined cigar box depth.

Commenting on the launch, Sam Simmons, Head of Whisky, said: “We are incredibly proud of this collection. These are five casks we kept coming back to – we knew we had something really special. This is the third series we’ve bottled at the old 80 Proof (UK). We believe 45.8% lets the spirit and the cask’s personality shine, while keeping everything balanced and genuinely drinkable. We take the liquid seriously, but we don’t think enjoying it has to be.”

Dave Worthington, Global Brand Ambassador, added: “For us, it’s about great whisky, and great whisky should be accessible, delicious, and fun. After tasting more than 300 casks, these were the ones that genuinely stood out. Or, put simply, they were just bloody delicious.”
