Don't know much about a science book? Who cares, when your pint glasses teach chemistry. This annotated pair teaches beer geeks about the naturally occurring molecules that give beer its mojo. Humulene, for example, creates that quintessential hoppy aroma. Ethyl acetate gives ales their fruity flavor. See? You know more already. A couple more sips, a few more annotated molecules, and you'll ace this exam. We hear the prof's an easy grader, anyway. Made in China.
