I (kind of) gave up booze for Lent. But I'm allowing myself Fancy beer. Partly because the idea of no alcohol for a month plus is abhorrent, partly because bock beer orignated (IIRC) as calories for monks fasting during Lent, and partly because what are you going to drink with fish & chips, Tang?
Anywho, the store had cans of "draught" Guinness. Since I don't get to drink Guiness as often as I'd like and since it pretty much fit all my criteria for Lent beer, I bought an 8 pack. It's OK. Didn't seem as good as what you get from a tap at a proper Irish pub, but there may have been some kind of...placebo?...effect? I'd need a scientific blind taste test to say for sure.
Anyways, NOT a bad purchasing decision. Had a nice little version of fish & chips with tartar sauce, a lemon wedge, cider vinegar for the fries, and some coleslaw with a glass of Guinness.
