Production & Heritage

Urban Chestnut Brewing Company operates out of St. Louis, Missouri, and has built a reputation for producing classically rooted German beer styles with exacting technical standards. O-Katz is brewed with Munich and Pilsner malts and hopped with traditional German varieties — Perle, Hallertauer, and Mittelfrueh — then fermented with UCBC's proprietary lager yeast strain developed in-house at the brewery's dedicated Quality Assurance Lab, which maintains hundreds of proprietary yeast cultures. The result occupies a deliberate middle ground between the heavier, maltier traditional Märzen style and the lighter, more restrained modern Festbier approach, a balance that has helped it dominate blind tastings of classical German styles brewed in America.

Tasting Notes

Aroma: Toasty malt rises first, followed by a layer of nutty sweetness and a faint honeyed warmth. Subtle herbal-grassy hop character sits quietly underneath, adding dimension without asserting itself.

Taste: The entry is bready and medium-bodied, immediately delivering rich Munich malt character. Mid-palate brings caramel and light brown sugar alongside a gentle toffee sweetness. Mild hop bitterness at 22 IBU provides just enough structure to keep the malt from becoming cloying, with a grassy herbal note threading through the finish.

Finish: Clean and surprisingly dry for a malt-forward lager, the finish avoids lingering sweetness. Residual toasted grain fades gradually, leaving a satisfying crispness that invites another sip.

How to Drink O-Katz

O-Katz is best served cold in a traditional Masskrug or wide-rimmed beer glass between 45–50°F, which allows the toasty malt aromatics to open up without warming the beer past its clean lager character. A Radler made with O-Katz and fresh lemonade plays beautifully off the malt sweetness on warm days. A Beergarita — blending Märzen with lime juice and a salted rim — gives the caramel malt a surprising citrus counterpoint. For a low-effort classic, a Shandy with ginger ale amplifies the toasty, bready backbone while keeping things refreshing.

• Hosting an Oktoberfest gathering with authentic German-style beer
