I stopped by a local dealer last Saturday and picked up two 1995 Cadenhead bottlings that both had bad corks.
Edradour 19 yr (1976 - 1995) 53.5% Brora 13 yr (1982 - 1995) 59.2%
The Edradour cork broke off in the bottle and had to be extracted with a corkscrew. The malt had a nose of "fresh cut wood and grass" (acurately reviewed by the enclosed brochure) but the palate was very soapy and perfumy (the famous FWP that Bowmore was accused of having a couple of years ago). The bottle is nearly undrinkable.
The cork in the Brora was damp, discolored and soft, even a bit "rotten" looking but the malt seems OK. The Brora smells of damp wood but is pleasant enough. The palate is damp wood, peat and some smoke with a touch of caramel or chocolate sweetness, a pleasant dram with Islay character.
I thought it a bit strange that the bottles had been sitting around for 11 years. Whether these were some old stock that Cadenhead couldn't sell elsewhere, or just my poor luck, I would be cautious of any whisky that has been in the bottle that long.
