I got him Rochefort 8, Rochefort 10, Westmalle Dubbel, Westmalle Tripel and Sierra Nevada Porter. I don't think he's tried any of those beers before and he seemed surprised when he saw the alcohol contents of the Belgian ones. I'm not sure whether I should lectuure him about how to serve them (temps. and glassware). I hate to think of him drinking them from pint glasses but I don't want to appear like a maniac either.
Anyway, I reckon it should be a nice introduction to Belgian beer.
