Local beer blog Brewpublic kicks off its ninth annual Killer Beer Week with a summit that includes special pours like a barrel-aged Scotch ale from Port Brewing and a mixed fermentation beer saison from Anchorage Brewing. Also hitting taps is Cultivating Mass, an imperial porter than has been quietly aging in bourbon barrels in Milwaukie for 18 months. On a related note, we prefer Lyft to Uber. Roscoe’s, 8105 SE Stark St. 5 pm. Free.

Six all-apple ciders compete for blind tasting supremacy — and a monthlong tap handle at Bushwhacker Cider — this weekend, providing you a perfect opportunity to get in tiny subjective arguments about dryness, tannins, and acidity while ignoring the tiny, subjective disagreements you got in at work this week. Bushwhacker Cider, 1212-D SE Powell Blvd. 6 pm. Free.

Killer Beer Week started Friday at Roscoe’s, but N.W.I.P.A. is kicking out the heart of the week with two days of killer IPAs. Saturday is hard-to-get out-of staters like Pizza Port, El Segundo, Columbus Brewing and Structures. Sunday is great double hazy IPAs from local spots like Great Notion and Ruse. Kick ass. N.W.I.P.A., 6350 SE Foster Rd. 2 pm. Free.

John Harris’ space-themed brewpub celebrates four trips around the sun with a barrel-aged imperial cherry porter and various other brewery-exclusive beers, in addition to providing small bites and live music. Ecliptic Brewing, 825 N Cook St. 11 am. Free.
