Couldn't quite get my dad what he wanted, which was clone recipes for some of Pyramid Brewing's selection of beers (they're big enough they don't want people cloning their recipes), so I opted for just a couple basic books, one about home brewing in general and one about brewing different styles of beer. The books were a huge hit, which shouldn't have been too much of a surprise, given that this is the same man that bought himself cooking text books to refine his cooking techniques and has been baking his own bakery quality french bread and making his own artisan cheese for the past three or four years, and has expressed an interest in roasting his own coffee as well.
