The American homebrew movement has the benefit of a day of their own, 7th May is recognised by the US congress as National Homebrew Day. The American Homebrewers Association (AHA) draw people together at the at a weekend close to that date to help celebrate with the Big Brew Event. This year they are holding it on the 5th May.
The idea is to get brewers together, around the world, to brew. Share in their brewing experiences and generally have a good day brewing with like minded people. It is also a great opportunity to introduce friends to your hobby. Perhaps you have a work colleague or neighbour who has shown an interest in what you do. Why not invite them along to help you brew, and share the spoils of the day with them. You may gain a new brewing colleague!
The AHA provide a couple of recipes for everyone to work from. This year the theme is Brown Ale, and one of the recipes has been provided by Matthew from the Oxford Brewers Group, the Ardley Brown Ale.
Information about the event can be found here and the recipes are available here
