I believe the most appropriate beers/ales for Agent would be those brewed by Unibroue
Seriously, they're in Quebec, and they're great - La Fin Du Monde ("The End of the World") is really tasty, and it's 9% ABV. Maudite is also quite tasty. Haven't tried any of their other varieties yet.
Basically, with alcohols, there are several things to consider:
- fresher is tastier, so if you can find a local brew, it will almost always taste better than something imported/trucked in. The exception to this is any large-scale domestic American beer (Bud, Miller, Coors, etc) - you can live in the brewery and it will still taste bad.
- if you like something a little sweeter and less "beer-like", you can either try a fruit beer - the Belgian-style "lambic" beers come in a variety of flavours, commonly cherry, raspberry, and strawberry. Also on the sweeter side are dark ales and German "festbock" beers (I've recently taken a liking to Holsten Festbock - pretty tasty, and the only Festbock I've seen around these parts).
- avoid any beers by "Faxe" (Danish, I think). They all taste like their secret ingredient is dead skunk.
- otherwise, beers/ales have been brewed for centuries if not millenia (apparently Egyptian slaves were fed strong beer to both nourish them and keep them pacified, and some have said the Sumerians wrote down beer recipes that archeologists have uncovered). There are many, many varieties - you can likely find 1 or 2 you like. Experimenting is half the fun
- find out if you're adversely affected by the tannins in red wine - some people are sensitive to them and get large headaches from it. If so, you'll have to stick with white, which limits your options.
- I'm a fan of red. I've found that a cabernet-merlot blend is generally a good overall choice - many producers in many countries make them, and they seem to be hard to screw up, and are generally middle-of-the-road in terms of sweetness and overall acidity.
- if you can't find cab-merlot, I've found a safe bet is an Australian cabernet sauvignon from Lindeman's - reasonably priced, consistent quality.
- in general, wines from Australia and Chile are safe bets and seem to be decent quality for a decent price (both have premium offerings now as well - some of the Masi wines are up there, but are extremely good)
- you'll have to see what you like. Personally, I'm a fan of amber/dark rum (Havana Club is my current favourite brand, but it's a Cuban import, which I doubt is available in the US). I'm not a fan of whiskey or Scotch (don't like the smokey flavour). I also enjoy good vodka - we recently started to get "Slava" brand 4x distilled from the Ukraine - very, very smooth (the same distillery makes a 3x distilled product called "Zirka", which is also very good, but you can tell it's not quite as smooth).
- in terms of mixed drinks, I usually drink a "Cuba Libre" (rum, coke, and a lime) or a "Screwdriver" (vodka and orange juice). Otherwise, not a fan of a lot of the fancy cocktails.
Also, incidentally, I've had Prairie Fires and I have to say, if you're at all into hot food I find them pretty light-weight.
Anyway, have fun
