Ailsa Bay Distillery
Ailsa Bay is a modern Lowland malt distillery built in 2007 within the William Grant & Sons Girvan grain distillery complex in South Ayrshire, Scotland. Named after Ailsa Craig — the distinctive granite island that sits off the Ayrshire coast — the distillery was conceived as a peated Lowland malt to fill a gap in Grant's portfolio alongside their Speyside malts Glenfiddich and The Balvenie and Highland malt Kininvie. Its water comes from the Penwapple reservoir. At capacity, Ailsa Bay can produce 12 million litres annually — making it one of the largest malt distilleries in Scotland despite its relative obscurity. It is not open to the public.

History
William Grant & Sons constructed Ailsa Bay in 2007 in just nine months, locating it adjacent to the existing Girvan grain whisky complex to take advantage of shared infrastructure. Production of malt spirit began shortly after construction. The official opening ceremony was held in 2009, attended by HRH Prince Charles. The distillery was designed to produce peated Lowland malt — an unusual combination, as Lowland single malts are almost universally unpeated. In March 2019 the distillery made headlines when it released a Scotch protected with blockchain technology to prevent counterfeiting. In September 2019, the Aerstone brand was launched under the Ailsa Bay umbrella — a pair of expressions (Land Cask and Sea Cask) aimed at whisky newcomers who find established malts "too complex with intimidating choice and language."
Production
Water is drawn from the Penwapple reservoir. The distillery runs eight wash stills and eight spirit stills — a configuration that enables the enormous annual capacity of approximately 12 million litres of pure alcohol. This makes Ailsa Bay one of the highest-capacity malt distilleries in Scotland, in stark contrast to its low public profile. The distillery produces spirit at two peating levels: the Sweet Smoke expression is deliberately balanced, with sweetness measured at 019 SPPM and peat smoke at 022 PPM — a tight specification that keeps peat present but not dominant. Maturation uses a combination of Bourbon, Virgin, First Fill, and refill American oak casks.
Tasting Character
The signature release, Ailsa Bay Sweet Smoke (Release 1.2 and subsequent numbered releases), balances sweetness with gentle peat in proportions unusual for both Lowland and peated single malts. Ex-bourbon cask maturation dominates, creating a mellow, accessible profile. Notes of vanilla, green apple, toffee, and a subtle wood smoke characterise the expression. The peat is present as background warmth rather than a frontal assault — quite unlike the heavily peated Islay style that many associate with Scottish smoke. The Aerstone Sea Cask and Land Cask variants are softer still, positioned for newer whisky drinkers.
