21st Amendment makes a watermelon beer so I do not know why more use of other melons have not been popular. A cantaloupe lambic would be interesting. Not a beer brewed with cantaloupe, but had serious cantaloupe and honeydew aromas and flavor, is Steel Toe Size 11 DIPA. Need to find out the hops used in that beer.
A great addition to an IPA in my opinion... i think Minneapolis town hall infused one at sometime and as Morimech said Size 11 had lots of melon in it
