Glen Grant 25 Year Old is a Speyside single malt Scotch whisky released in 2024 as part of the distillery’s Glasshouse Collection. Matured for over two decades in American oak bourbon barrels and Oloroso sherry casks, it’s bottled at 46% ABV with natural color and no chill filtration. Crafted in Rothes, Scotland, the whisky reflects Glen Grant’s signature light, fruity style shaped by tall stills and wooden washbacks.
