Signatory Vintage Secret Orkney 19 Years was produced in Orkney, Scotland, and matured for 19 years in a first-fill Oloroso sherry butt. Distilled on May 7, 2005, and bottled on June 18, 2024, by Signatory Vintage for its Cask Strength Collection, it is bottled at 54.4% ABV in a 700ml format.
Rather superb, though it may not totally measure up to the finest ex-bourbon or refill hogshead versions in my book (but those are rarer than one might wish). That said, not the case at all here, but heavy sherry casks like this can sometimes also be proper burdens.
