Six-year-matured single malt bottled at 56% ABV without chill filtration
Isle of Arran Distillers has unveiled a new Small Batch release from Lagg Distillery, exploring the influence of fresh Quarter Cask maturation. Lagg, on the southern edge of the Isle of Arran, laid down its first heavily peated spirit in 2019. The new release is the distillery’s third Small Batch expression to be released worldwide, and is available now from whisky retailers in selected global markets at an RRP of £84.99.
The company said Lagg has developed into an international brand with a reputation for expressive, characterful single malts, supported by a brand campaign. Its Kilmory and Corriecravie Editions sit at the centre of the range, which the company said reveal different dimensions of the distillery’s character through opposite maturation approaches.
Following the releases of the Palo Cortado Small Batch in 2025 and the Manzanilla Sherry Finish earlier this year, Lagg has turned its attention from sherry casks to American oak. The heavily peated spirit was matured for six full years in 125-litre Quarter Casks, rebuilt from former Bourbon barrels and selected by Distillery Manager Graham Omand. According to the release, the smaller cask format creates greater contact between whisky and wood than a standard barrel, intensifying the influence of the oak and allowing richer, more concentrated flavours to develop during maturation.
“We love seeing Lagg Single Malt in this more concentrated form,” said Lagg Distillery Manager Graham Omand. “The quarter casks bring all of the flavours we know and love into sharper focus. Classic vanilla, citrus and warming oak spice sit around the ashy smoke with real intensity in this dram, while the oily and robust character that defines Lagg Single Malt remains unmistakably at its core.”

The Lagg Small Batch Quarter Cask is bottled at 56% ABV, without chill filtration or added colour. The release describes the whisky as pale golden in colour with straw-coloured highlights. On the nose, it is described as showing sweet peat followed by creamy butterscotch and toasted oak, with citrus peel, orchard fruit, sea spray, charred driftwood and herbal freshness emerging beneath the smoke.
The palate is described as rich, full-bodied and oily, with vanilla fudge giving way to earthy peat smoke, cracked black pepper and warming oak spice, followed by grilled lemon, toasted coconut and honeyed malt. The finish is described as long, warming and smoky, with embers and maritime salinity softening into vanilla sweetness and citrus freshness.
The company said the release continues to demonstrate the versatility of Lagg’s heavily peated spirit, this time through small-cask maturation.
