A beer has to be pretty darn awful for me to not finish drinking it. The only time I have cried uncle in recent memory was with a Gonzo Imperial Porter. To me, beer should not taste like booze, much less diesel fuel like this one did. I didn't recognize any of the beers on the list and the list provided no descriptions or even style designations for the various beers, so I asked the waitress for something "malty and dark", and this is what she brought me.
Some other duds up here in Canada that I've had recently: Creemore Premium Lager, Kawartha Lakes Raspberry Wheat, and Hop City Brewing Lawn Chair Weisse. I at least finished all of those, though.
