More than 40 winter beers and ciders from around the region pour under the 75-foot city tree in Pioneer Courthouse Square. Holiday releases are the point here: the seasonal, once-a-year pours that breweries save for the dark months, sampled in the middle of downtown with the lights overhead. The fest runs Friday evening and all day Saturday, so Saturday afternoon is the easygoing session and Friday night the lively one. Strictly 21 and over; buy tickets ahead through the festival's site.
