Winter is almost exclusively Guinness (Closest I got to the factory was drinking a lot of it in Belfast). Sam Adams and Blue Point brewery Octoberfest brews. Sam Adams Boston Lager, Yuengling, Brooklyn Brewery does a good job of pretty much everything.
There are a couple of good Beers from New Zealand SPEIGHTS, MAC's Great White wheat beer.
The beer I pine for more than any other is South African Brewery's Castle Lager (the version Brewed in Zimbabwe, not South Africa). I was very excited when I heard SAB had brought out Miller (SAB is (or at least was a few years ago) the biggest brewer in the world) as I thought they would bring Castle to the USA, but no such luck, they rightly thought it would kick the shit out of other Miller products :wall:
Windhoek Lager from Namibia deserves an honorable mention as well.
I will drink Bud, Coors etc... without hesitation, as long as it's cold, and in a bottle/can, not from a tap.
On nasty hot days I enjoy a Corona with Lime or a Landshark (which I've recently discovered is brewed in Missouri. I was disappointed as I thought it was from Hawaii, which is where I first had one).
I'm very interested in brewing my own beer, and Mead, and Sake.
