If you're in the area or already here, I'm currently enjoying some Strawberry Cream and other fruity sour beers at Cascade Barrel Room. Hit me up or swing by if you want to try some Bruery Sour in the Rye with Peaches.
Just a quick trip through Portland, unfortunately. Been too long since I've visited Seattle, though. I'm hoping to make a return visit to the Northwest within the next year. I'll let you know if/when I'm passing through.
