Isle of Arran’s Lagg Distillery, has announced the launch of a new small-batch release, exploring the influence of fresh quarter cask maturation.

Lagg Small Batch Quarter Cask (56% ABV) is a peated (50 PPM) single malt Scotch whisky, matured for six years in 125-litre quarter casks, rebuilt from former ex-Bourbon barrels and selected by Distillery Manager Graham Omand.

The smaller cask format creates significantly greater contact between the whisky and the wood than a standard barrel, intensifying the influence of the oak and allowing richer, more concentrated flavours to develop throughout maturation.

Following the successful releases of Palo Cortado Small Batch in 2025 and Manzanilla Sherry Finish earlier this year, Lagg now turns its attention from rare Sherry casks to the powerful influence of active American oak. The new expression is the distillery’s third Small Batch release to be made available worldwide.

Since opening its doors and laying down its first heavily peated spirit in 2019, the distillery has grown into an international brand, earning a reputation for expressive, characterful single malts that embrace contrasting and intriguing flavours. Supported by an award-winning brand campaign, Lagg continues to bring its distinctive peated style to whisky drinkers around the world.

Lagg Small Batch Quarter Cask, is said to offer aromas of sweet peat, creamy butterscotch, toasted oak, citrus peel, orchard fruit, sea spray, charred driftwood and gentle herbal freshness. On the palate, these are followed by notes of vanilla fudge, peat smoke, cracked black pepper, oak spice, grilled lemon, toasted coconut and honeyed malt.

Commenting on the launch, Graham Omand, Lagg Distillery Manager, said: “We love seeing Lagg Single Malt in this more concentrated form. 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.”

Lagg Small Batch Quarter Cask, is now available from selected specialist retailers, for a RRP of £84.99.
