Surprised by this 21yr old Auchentoshan. It looks like it is from a bourbon cask but is actually from a refill sherry cask. Has loads of nice woddy notes - again confusing as I am still thinking bourbon, but it does not have that sugar from the wood, but from the sherry. Softness from the sherry apears on the finish. Just delicious at a great price - IF you can still find some.
