Benromach from before 1983, when the distillery shut-down, is basically whisky from a lost distillery. Nobody regards it as such, which I totally get, but still, I think my reasoning makes sense, no?
One of the most elusive Scotch whiskies, Brora has gained a cult status only after it was closed in 1983. Today I try a single cask bottling from Signatory Vintage.
