Esters give fruit flavors

From the July-August 2010 issue of Michigan Beer Guide. This is a pretty neat article about the esters that yeast produce when fermenting, which in turn, give the beer fruity flavors, as esters give fruit flavors (food science!). I especially enjoyed the part about isoamyl acetate which is both produced by bananas and bees (when they sting you). Since bees start losing internal organs as soon as it stings you, the main threat is the other bees that come after you, attracted by this phermone they left at you, at which point, you'd better start moving.
