Glengoyne craft Whiskies from Oak cask and Sherry casks. This is what gives them their very different colouration. Some whiskies have an AVB (alcohol by volume) of up to 58.7% which adds to the taste. With Hints of ripe apples in the oak cask whiskies and strawberries and cinnamon tastes from the sherry cask whiskies, Glengoyne does not take half measures, only doubles.
