For the GlenAllachie Virgin Oak series, the whisky is initially aged in ex-bourbon casks made from American oak (Quercus Alba). To impart a delicate and distinctive note, the whisky is then further aged for approximately 18 months in specially selected virgin oak casks. The subtle flavor differences in this series are influenced by a variety of factors: the types of oak, the local terroir, the duration of natural air drying, as well as the toasting, charring, and crafting of the barrels. Each of these interacts uniquely with the GlenAllachie distillate, contributing to its excellent texture, depth, and complexity. This rich bronze whisky derives its silky tannins, sweet spices, and fruity notes from hogsheads made of French oak (Quercus Robur) sourced from the Haute-Garonne region near the Pyrenees. The fine-grained, uniform wood is air-dried for 15 months before the GlenAllachie distillate is filled in. The result is a delicious, subtle, and earthy single malt. Limited to 6,600 bottles worldwide.
