Nothing says “Oktoberfest” like oompah music, dancing and giant glasses of beer. Celebrations begin at Biergarten Haus Saturday. (Evy Mages/For The Washington Post)

Beer

Belgian beer geeks have had 3 p.m. Saturday circled on their calendar for a while now: It’s the annual release of Zwanze, a crazy-delicious lambic beer that is “spontaneously fermented” with wild yeast. Due to bootleggers selling bottles of last year’s Zwanze for 10 to 12 times its original price online, the brewers have decided that this year’s Zwanze will only be available on draft. There are just 20 kegs worldwide, and ChurchKey is tapping the only one in the region at 3 p.m. It will be a madhouse. Beer sommelier Greg Engert is encouraging people to arrive “really early” on Saturday to avoid disappointment.

Meanwhile, Saturday is also the beginning of Oktoberfest in Munich. There are two great reasons for German beer fans to head to the H Street Festival: Biergarten Haus will be celebrating Oktoberfest with eight festbiers, including Spaten, Paulaner, Hacker Pschorr, Hofbrau, Warsteiner, Erdinger, Becks and Kaltenberg, from the same brewery that makes the Biergarten’s staple Konig Ludwig. Look out for live music and German dancers all day; expect one liter (33.8 ounce) mugs to sell for $15 to $17.

Also at the H Street Festival: DC Brau unveils its new seasonal beer, Atlas Fest Bier. Meet the DC Brau brewers (and pick up some swag) at the DC Brau booth in front of Little Miss Whiskey’s between 1 and 7 p.m.

Boxing

During yesterday’s Got Plans chat, we had a few readers ask where to watch Floyd Mayweather Jr. take on Junior Ortiz in the welterweight title fight. Our suggestions include Public Bar, which will have the bout on dozens of TVs; Redline, which will have the fight on an 11-foot HD projection screen in addition to 40 TVs; McFadden’s, where the night includes an optional $30 open bar from 9 to midnight; Barcode and Bayou.

‘90s Nostalgia

Finally: After finding some early-’90s WHFS year-end playlists online the other night, I found myself rocking out to the Soup Dragons, the Sugarcubes, Matthew Sweet and the long-lost “If You Don’t Love Me (I’ll Kill Myself)” by Pete Droge. (You can listen to the 1992 and 1994 lists.) If you find yourself in a similar mood for Clinton-era jams this weekend, there are two opportunities. Tonight, the four-times-a-year No Scrubs dance party is back at the 9:30 Club on short notice after the Kaiser Chiefs cancelled. DJs Brian Billion and Will Eastman drop everything from Nirvana to Johnny Gill to Technotronic at these wildly popular all-ages events. Tickets usually sell out in advance; I’m guessing it will be easier to get in than normal. If you’ve missed No Scrubs before, these preview mixes will show you what to expect.

Tomorrow night, Peach Pit returns for its monthly appearance at DC9. Soul II Soul, Madonna, the Spice Girls (whose picture adorns this month’s flyer) -- DJ Matt Bailer keeps the dance floor moving. Admission is $5; doors open at 9.
