My favourites
1. Any of the Big 6 Munchener Helles (Spaten and Augustiner in particular)
2. Hacker-Pschorr Hefe-Weizen (taste of it is more to my liking than Schneiderweisse or Erding although Paulaner is very good)
3. Caledonian 80/- Great Scotch ale
4. Canadian beer. Wellington County Ale,any of the Unibroue beers and Big Rock Trad or Grasshopper on a hot day.
5. American beer. I'd have to say Sierra Nevada Pale Ale although that could be because the first time I drank it was in the Fillmore listening to a great band and looking out over San Francisco Bay at night through the bar's windows.
