Urban Chestnut Brewing Co. celebrates its ninth anniversary with its always popular Wolpertinger festival. (A wolpertinger is a creature from German folklore; it's like a hare with antlers, and at Urban Chestnut, he wears lederhosen.) Wolpertinger is also a celebration of the local craft brewing scene, with more than 45 breweries offering samples at the fest. This year's guest brewery of honor is Karmeliten Brauerei from the Bavarian city of Straubing, Germany. Wolpertinger takes place from 1 to 5 p.m. Sunday, January 26, at Urban Chestnut's Grove Brewery & Bierhall (4465 Manchester Avenue; www.urbanchestnut.com). Tickets are $40 and include a commemorative tasting glass and unlimited beer samples. Designated driver tickets are $5.
