Diebolt Brewing Company
A father-and-son team (Dan and Jack Diebolt) quietly brews French-style ales out of a former meat-packing warehouse on a side street in Sunnyside — biere de garde, saison, French amber, a tradition basically no other American brewery bothers with. Their barrel-aged imperial stout 'Vladislav' took Gold at the 2018 World Beer Cup and Gold again at the 2025 Great American Beer Festival, yet the taproom stays so low-key it's mostly just neighbors and beer obsessives. There's no flashy sign and no crowd; it reads like a garage with a tap list. Order the Biere de Triomphe (Cabernet-barrel biere de garde) and you're drinking something you can't get almost anywhere else in the country.
The story
In a craft beer city obsessed with hazy IPAs and crisp Czech lagers, father-and-son duo Dan and Jack Diebolt chose a weirdly specific, almost forgotten hill to die on: French farmhouse ales [1.2.7]. Founded in 2013 inside a former meat-packing warehouse at 3855 Mariposa Street in Sunnyside, Diebolt Brewing Company operates on a side street where you'd sooner expect a body shop than a French cellar. While everyone else raced to hop-heavy trends, the Diebolts quietly began turning out bières de garde, saisons, and French ambers—traditional styles rooted in northern French farmsteads that almost no other brewery in America bothers to touch.
There is no flashy sign out front, which keeps the spot feeling like a private garage with a tap list. But behind that modest residential exterior lies serious brewing chops. Their barrel-aged imperial stout, Vladislav—originally named 'The Commodore' before a trademark snag forced a name swap referencing an '80s movie and '90s dance hook—took Gold at the 2018 World Beer Cup and Gold again at the 2025 Great American Beer Festival. Yet despite the national hardware, Dan and Jack have kept the taproom resolutely low-key.
Sit down at the bar and skip the standard picks. Order the Biere de Triomphe—a bière de garde aged in Cabernet barrels—and you're drinking a malty, barrel-kissed French style that you virtually cannot get anywhere else in the country. It is a conspiratorial little neighborhood secret: world-class barrel aging and rare French brewing heritage, hiding out on a quiet residential block in Sunnyside.
What it's like
You pull up to a quiet residential side street off the Tejon and 44th corridor expecting a slick brewery compound, but Diebolt feels more like hanging out in a neighbor's garage taproom. Inside, there are no long lines or velvet ropes—just Sunnyside locals, off-duty beer obsessives, and dogs chilling in the cozy taproom or out on the small front patio. Street parking is usually easy, though you'll want to keep your voice down for the neighbors when walking back out. Food comes via rotating food trucks parked outside or simple in-house snacks like pretzels and chips. Grab a saison flight or split a barrel-aged bottle and let the bartender explain why French farmhouse yeasts taste like nothing else on tap.
The move: Post up in the casual taproom or the patio, split a barrel-aged bottle and a saison flight, and let the bartender walk you through why French farmhouse ales taste like nothing else on the shelf.
📍 Before you go Diebolt sits on a quiet residential side street in Sunnyside, just off the Tejon and 44th corridor — there's no parking lot, but street parking is usually easy; keep noise down for the neighbors. The small front patio is the move in warm months, while the cozy interior carries the colder ones. Food is via rotating trucks plus in-house snacks like pretzels and chips, so check what's parked out front (or plan to grab a bite nearby). It's dog- and family-friendly and rarely crowded. Pair a visit with a wander down Tejon Street's Sunnyside spots. Hours shift seasonally — confirm ahead.
