anyone who posted a macro, adjunct lager, or tasteless swill should die, unless you stated that it is strictly for budgetary purposes.
anyway, you can't really have one favorite beer. Are you going to drink a stout outside in the summer heat, or a citrus wheat beer by the fireplace in the winter? no. right now I'm getting into scottish beers, and the category of wee heavy. Oskar blues has a ripping scottish ale, and they have an awesome restaurant/brewery in Lyons Colorado.
don't be fooled by the can. environmentally friendly packaging is big in the craft beer industry.
