I made a blackberry melomel and interested in entering it into a contest to see how it does. Never entered anything into a contest before. Are there any contest you would suggest coming up?
You could always try local county/state fairs, they'll generally have a little wine competition for local homebrewers/wineries/breweries. Other than that, look in your newspaper for local wine gatherings, beer fests, etc.
Whichever you find, just make sure to let us know how you did...
