I brewed a saison and added lemon zest for the last five minutes of the boil. At the time, it seemed like a lot of lemon zest, but I was following a recipe. The beer was in primary for a week, secondary for a week, and in bottles for two weeks. When I tasted it, I could not detect any lemon at all - not in the smell or taste. However, when I rinsed out the bottle with hot water, the lemon scent became extremely potent - almost like Lemon Pledge.
My question is: Is there something unique about lemon zest that would have caused this effect, or did I simply not add enough?
