I think I just like to drink a lot of beer at one time! But, unlike frat boys (whose solution to the same problem is to drink godawful watery stuff like Miller Lite) I prefer to drink really good beer if I'm going to drink beer at all. And this fruity-sweet super-intense pseudo-Belgian style is really better in smaller quantities, since it gets to be over the top after the first pint. It's also a very heavy beer, which contributes to making it less drinkable in larger quantities, particularly if you combine it with a meal. In all likelihood, this is not a problem for Trappist monks, but I suspect they have more of a commitment to “moderation in all things” than I will ever have.
So, while I don't think I'll be buying another bottle of The Reverend anytime soon, that doesn't mean you shouldn't. It's a good beer, and I enjoyed it- I just can't drink as much of it at one time as I might prefer, and that's why I generally go for the Imperial Russian stouts instead!
