As Fall finally takes a tumble into our laps, so to do some of Germany's finest amber lagers.

Oktoberfest is upon us, and that mean's Munich's largely export-only brews finally tap at alehouses the nation over. And in the midst of all that, many local breweries tap their latest fresh-hop creations, with others still release new varieties of dried-hop IPA just for the change of season.

Wherever you turn this week, there are new beers pouring. If ever there were a time for a seasonal beer crawl, this is it.

Ruse Brewing Architect Release Party

BeerMongers Oktoberfest Celebration

The mongers grabbed an armload of imports and terrific regionally-brewed festbiers for their annual Oktoberfest celebration, featuring options from pFriem, Paulaner, Hacker Pschorr and more. Consider this among the best places to celebrate this harvest season without massive young crowds or public urination of any kind. The BeerMongers, 1125 SE Division St. 5 pm-12 am, September 17-18.

Complete IPA Book and Beer Release

Breakside celebrates the release of author Josh Bernstein's Complete IPA book with a hoppy ale of the same name. Brewed using what the brewery describes as a "copious amount" of Citra and Mosaic hops — which by Breakside standards should be a MASSIVE amount — the new ale should be a dank and deep dive into the world of contemporary IPAs. Breakside Brewery, 820 NE Dekum St. 2-4 pm. Free.

Widmer x Timbers Centennial IPA Release

In celebration of 100 consecutive sold-out home games, the Timbers and partner brewery Widmer teamed up to brew a fresh batch of the hoppy stuff. An IPA made with a healthy dose of centennial hops can be enjoyed this evening, and there may be some team members stopping by for a pint after their 3 pm match at Providence Park. Widmer Brothers Pub, 955 N Russell St. 6-8 pm.

Sunday, September 18

Space Invader IPA Release

The latest hazy creation from New England-style IPA haus Great Notion is their first batch brewed with Australian galaxy hops. Tropical and dank, it should be a perfect pairing to their opaque and full-bodied take on the hoppy ale. Great Notion Brewing and Barrel House, 2204 NE Alberta St. #101. 12-10 pm.

Manic Monday with de Garde

As the profile of Tillamook's de Garde Brewing continues to grow in the world of sour beer — where they are continually recognized as one of North America's best ale apothicaries — bottles of the good stuff are flying off the shelves faster than ever before. Consider it a blessing, then, that Belmont Station has secured a massive smattering of their finest stuff for this Monday night bash, with bottles and two freshly nectarine-infused beers on draft. Belmont Station, 4500 SE Stark St. 12-11 pm. Free.
