The local club also does an Iron Mash competition. We get a box of the key ingredients--hops, grain and yeast--and brew at one of the local breweries so there's hot and cold water already available. Then there's a second box of special ingredients that contains four spices/fruit/who knows. You have to use all of one of the special ingredients and at least a small amount of the other three.
I haven't decided whether to compete this year (and it would be my first) but I'm interested in seeing what ingredients they give out and what kinds of beer people are making.
