Hmm...Pilsner and Moose Head are pretty good. I also like Kokanee, but never drank it for a few years.
Lager? Or alcohol in general? My favorite lager is heineken, although I haven't tried much lager. For alcohol in general, I'd say holy water or somersby (blackberry).
I love stouts, specifically oatmeal, coffee and milk stouts. Left Hand wins for the best Mil Stout and New Holland's oatmeal stout is by far my favorite beer of all time. As for the coffee stouts- I have had several good ones from small craft breweries, but if you are ever in Southern Illinois get Schlafleys version.
When I used to still drink alcohol, I loved Black Label beer. Now I drink alcohol-free "beer" like Bavaria (various flavours available) or Beck's. It doesn't quite taste the same as alcohol-containing Black Label (Because there's only ONE ) but beggars can't be choosers, eh?
Michelob Ultra. Dos Equis is a close second. But mostly I'm a whiskey drinker. Evan Williams white label.
