I've just realised it's the county show (Thame) coming up at the end of next month, and I see that they have (buried amongst the various flower, cake and vegetable classes...) a "Beer" competition class. Was half-tempted to enter something in, though wonder if anyone has done similar (in this or another county/local show)? You see, the class is somewhat "vague":
1 bottle of beer, bitter type.
In brown bottle, 330-350ml crown stopper.
And that's it...! (Rather odd bottle size, no starting gravity, no idea on the judging (though members of the Thame Wine Circle judging, so I'm guessing NGWBJ...?)...)
