Generally, low OG recipes without alot of complexity. Like, mild for example. Last year, we did a beer swap (called 10der and mild, if you want to look for it) that involved milds. The catch? It had to be sent out 10 days after brewday. And they were all good, although I noticed that mine improved with age.
A hefeweizen would be good young. Also, a simple pale ale without many specialty grains and low IBUs. Most wheat beers would be good young, too.
