The annual Bierfest (http://www.bierfest.de) Kulmbach Beer Festival begins on the last Saturday in July and continues through until the first weekend in August. Be advised that getting accommodation might be a bit difficult at the time of the Bierfest. But not impossible, if you're early enough with for reservations.
The Alstadtfest Old Town Festival takes place on the first weekend in July and is organised by the restaurants, bars and pubs in the old part of the town.
