While reading For the Love of Hops today, I found this statement particularly intriguing: "One third of the population is blind to beta-ionone, a compound with a floral note particularly prominent in Saaz hops. another third is extremely sensitive." (40). Why, you ask? A few months ago I was judging a club only comp for American Pale Ales and one smelled like straight floral perfume, heavy rose water, but no one else picked up on this aroma. I couldn't get past it at all, and others thought I was nuts. Just goes to show how subjective judging beer can be (Hieronymus does state that the more you train your nose, you can begin to pick up things that you couldn't before).
