I suspect there was a problem with the refill hogshead cask this whisky was matured in. My reason for buying this bottle was that all of the Mortlachs that I have were matured in refill sherry butts, and I thought it would be interesting to try this one and compare the cask influces. My advice is to avoid this one or obtain a sample and try before buying if you can. There are far better Mortlachs available.
Vinegar. Very acidic and sour on the nose.
The arrival is rich, malty sweetness that is a trademark of Mortlach, but it very quickly develops astringency and turns dry. Not entirely unpleasant but also not what one would expect from a Mortlach.
Medium length and mouth drying.
