Pull out your pretzel necklace because the Pittsburgh Winter Beerfest is back for a sixth year. More than 100 breweries — a mix of local, national, and international — lug their kegs to the David L. Lawrence Convention Center Feb. 22-23. Every brew enthusiast gets a five-ounce tasting glass with their ticket, ready for unlimited pours. Need more beer? Upgrade to an early admission ticket for exclusive access and an eight-ounce mug.
