Good flavour? All in good time. It’s the magic of the cask that lends The Famous Grouse its unique flavour. The European oak we use in our sherry casks and the American oak in our bourbon ones make sure each dram is full of flavour. Each has its own qualities, and each adds its own subtle shades of character to the whiskies that go into The Famous Grouse. By choosing one over another, we can add a little sweetness, a rich, toasty undertone, or a bright fruity note.
