The Glasgow Distillery’s Small Batch Series
The Glasgow Distillery’s Small Batch Series is a limited-edition collection that celebrates the versatility of its single malt whisky. Each release explores new cask maturations across the distillery’s three house styles - unpeated, peated, and triple distilled - showcasing the creativity and character of Glasgow’s contemporary urban distillery.
Introducing: Glasgow 1770 Passito di Caluso Cask Finish
This five-year-old limited edition bottling is drawn from two robust sweet wine casks (20/1627 and 20/1629). These two casks were initially filled with the distillery’s rich and smoky double distilled peated new make spirit on the 12th of October 2020 and matured for 3 years and 8 months in first fill Wild Turkey ex-Bourbon barrels, before being reracked into Passito di Caluso sweet dessert wine hogsheads on the 17th of June 2024. The whisky then matured for a further 1 year and 8 months, before being bottled on the 16th of March 2026.
Bottled at a robust 57.8% ABV with only 690 bottles available, this release highlights The Glasgow Distillery’s rich and smoky peated single malt style alongside the rich and savoury Italian sweet wine casks. Expect BBQ smoke, coastal maritime salinity, rich caramel and black pepper spice.
Meet Passito di Caluso
Passito di Caluso is a traditional Italian sweet wine produced in the Canavese area of the Piedmont region in north-western Italy, around the town of Caluso, just north-east of Turin.
It holds DOCG (Denominazione di Origine Controllata e Garantita) status and is made exclusively from the Erbaluce grape, an ancient local white variety known for its naturally high acidity and aromatic profile, two qualities that make it particularly well suited for crisp dry wine, sparkline wine, and sweet wines.
The wine is made using the appasimento method, the same method used for the production of Amarone and Recioto, where Erbaluce grapes are harvested in late autumn and then air-dried for several months on mats or racks. This dehydration concentrates sugars, acidity, and aromatic compounds, resulting in a dense, sweet must.
After pressing the wine is slowly fermented, typically lasting a couple of months and then matured for an extended period. DOCG rules require a minimum of 4 years aging, though many producers age significantly longer. This combination of concentration and slow oxygen exposure builds complexity and longevity.
Passito di Caluso tends to be rich yet lifted, balancing sweetness with a spine of bright acidity and typically provides the drinker with notes of dried apricot, candied citrus, honey, dried herbs, and a nutty profile.
The palate is usually viscous and sweet, but with a high acidity profile keeping the wine fresh and crisp.
The casks used for this single malt are 225 litre European oak hogsheads that have held Passito di Caluso in them since 2016, providing an ample amount of residual complexity and character that elevates The Glasgow Distillery’s rich and smoky peated malt profile.

Tasting Notes:
Nose: Coastal, opening with a gentle salinity and sweet, drifting smoke. Notes of sun-dried hay and polished wood emerge, layered with candle wax, bright lemon zest and an underlying earthy depth.
Palate: Rich yet composed, with honeyed sweetness carrying flavours of dried apricot and maritime air, wrapped in waves of soft smoke and smoked sea salt.
Finish: Long and satisfying, remaining rich and honeyed to the end. Baked banana and candied ginger develop alongside lingering candle wax and a mineralic smoky glow.
