February 14 may be set aside for amorous couples marking the Feast of St Valentine, but this year lovers of beer will have something to celebrate as Zwickelmania returns. Billed as an ‘Oregon brewery tour' it’s a great opportunity to visit breweries that are normally closed to the public, peep behind the scenes, and (obviously) taste some great beer. Statewide there are over 110 breweries involved, though most are based in Portland, and many will be offering limited release taps and bottles, plus tours, brunch and happy hours. The Brewvana bus will be in action riding between eight of the breweries, but to make the most of the day and to seek out some of the smaller participants check out the full list here. One stop worth checking is Migration Brewing who will be throwing a party for their fifth anniversary with samples and some specialty aged beers. Zwickelmania, Saturday, 11 am-4 pm; Migration, 2828 NE Glisan
