I have not had many single grains. Honestly I think prior to this it's only haig club and despite that being an offering from the same distillery haig club is not good so I was hesitant going into this one. I tried the 27 year old batch 3 but since there's no entry I'm entering my thoughts here. Notes of cocoa powder, hay, citrus and a bit of an almost barnyard funk. But not in an unpleasant way. Oldest whiskey I've tried to date.
