Best of luck in the competitions - one thing to realize is that any number of handling issues can affect your entries, so be ready to take that into account. It is a good idea to keep a sample back to drink with the scoresheet in hand, because if the judge noted a specific condition, it may have arisen after leaving your hands or it may have simply arisen over the delay in time from some other reason. Especially with the light beers - they just don’t always hold up if stored warm, for example. I like to bottle condition for this reason, when possible.
