In case you haven’t heard of Steve Duncan, he’s a “guerilla” historian and photographer who has made a name for himself exploring parts of New York City that you probably didn’t even know existed. In the latest installment of his Undercity documentary series with filmmaker Andrew Wonder, Duncan hops over a barbed wire fence, pries open a manhole, and climbs down to the ancient sewage extension tunnels below Bushwick.

Well, the tunnels aren’t quite “ancient,” but they date back to the bygone days before brunch at Northeast Kingdom and whiskey shots at Tandem, before Brooklyn was even a part of New York City. In the 1880s when the sewer extension was built below Knickerbocker St., the area was known for its breweries. The tunnels carried wastewater from the breweries to the East River, Duncan explains in the clip, ankle deep in (clean) sewage water.

The whole outing is illegal, but Duncan provides a special view into our historic city. More on Gothamist.

The Reverend Vince Anderson and his Love Choir have become an institution, holding mass every Monday night at Union Pool. Self-described as “dirty gospel,” the Rev. gives a soulful, optimistic and uplifting performance every week. This past Monday, to celebrate his birthday and toast his relationship with Union Pool, Vince teamed up with SixPoint Brewery to create his own beer. Here is the making of SixPoint Instant Pentecostal Apostle.

We’ve already been infinitely impressed this summer by Smorgasburg, the Brooklyn Flea‘s weekly event bringing a bazaar of delicious food to the Williamsburg Waterfront. Now – perfectly timed but not affiliated with the NYC Craft Beer Week - the Flea (along with the DUMBO Improvement District) is putting on this food- and beer-centric event, Under the Archway.

From 12-9 today, head down to DUMBO, to the Archway under the Manhattan Bridge to enjoy food from Mile End Chinese Food, Rachel’s Pies and more. More importantly, though, wash this food down with delicious craft beer on tap from Stoudts and Sixpoint.

According to the Flea’s site, “We’re going to activate this unique public space and help knit together the neighborhood by getting residents and workers out for a fun Friday hang.” If you’re in the area for lunch, food starts at noon. For the after work crowd, the beer will start flowing at 3, and the whole event will keep going until 9 pm.

Although it’s only Tuesday morning, it’s not too early to begin making your weekend drinking plans. We highly suggest kicking off the New Year by stopping by the 4th Annual Williamsburg Cask Beer Festival at dba Brooklyn. What is cask beer you may ask? It’s unfiltered, unpasteurized beer brewed from traditional ingredients, matured and naturally carbonated by a second fermentation in the container from which it is manually dispensed. It’s typically served at cellar temperature, which is about 54 degrees.

The Cask Beer Festival takes place Friday 1/7 to Sunday 1/9 from 1pm onward at dba Brookly which is located at 113 North 7th Street. The festival will feature at least 15 rare and delicious cask beers tapped simultaneously. There’s no entry fee, and you pay per drink.

Here’s a last minute plan for tomorrow night: a nine course beer tasting paired with a German dinner at Lorely Williamsburg from 7-10:30pm.

Rudi Eilers, a German beer expert, will introduce 9 different beers from Germany (list below) and discuss each beer’s origin, brewing method (top vs. bottom fermented) and unique flavors.

7. Köstritzer Schwarzbier – the most popular dark beer in Germany, surprisingly light and fresh

8. HB Strong Bock – a bottom fermented light bock with powerful aromatic flavors

9. Einbecker Winter-Bock – a deep amber red beer with malty sweetness balanced by a hoppy bitter finish

Tickets are $29 and can be purchased here.
