Bad cooperage and a lousy market probably have a lot to do with this one. Things still weren't too hot in the late-70s and they probably tossed the new make into whatever cask was handy, rather than carefully picking one. On the other end, things were still pretty dead in the 90s, so Cadenhead's may have bottled it to cut their losses and get it out of the warehouse. How could they have predicted that so many people would be excited about a dead distillery that almost never put out single malts?
