Collaboration beers by teams of area brewers, always a highlight of Spokane Craft Beer Week, take center stage on today's schedule at a new location: 

– In a last-minute switch due to unforeseen circumstances, this year's CollabFest has been moved to Iron Goat (not the previously announced Bellwether) from 4 to 8 p.m. Admission is $10, which includes a commemorative glass and four drink tickets. Additional tickets are $2 each or three for $5. 

There should be no shortage of sours, including a tangerine/soursop rendition from Iron Goat and Chewelah's Quartzite, the OMG orange/mango/guava version from River City and Waddell's, and a dry-hopped, blended barrel-aged sour from No-Li and Genus. Also look for the No ReSt saison from Northern Ales, Republic Brewing and the Steam Plant; a strawberry hefeweizen from Orlison and Whistle Punk; a mimosa-style Et tu, Brute? IPA from Four-Eyed Guys and Waddell's; and the Bring Your Wellies oyster stout by Bellwether and Millwood Brewing, among others.

Bring donations of new or like-new clothing for children, infants to teen, to get raffle tickets toward brewery merchandise.
