Mendig: Guided tour in the 30m deep volcanic beer cellar

If you’re looking for an experience that combines a bit of adventure with a splash of history—and, of course, a good dose of beer—then the guided tour of Mendig’s volcanic beer cellar might just be your thing. This isn’t your typical brewery visit; it’s a descent into the depths of the earth, where the unique relationship between volcanic activity and brewing makes for some fascinating stories.

What I really like about this tour is how it offers a chance to see the world’s deepest beer cellar—a full 30 meters underground—while also learning about how natural forces shaped local brewing traditions. Plus, the highlight for beer lovers is definitely tasting the Bourbon Barrel Doppelbock, which is stored in original bourbon barrels from the USA.

However, a key consideration is that the tour involves descending 153 steps into the cellar, which could be a challenge for those with walking difficulties, circulatory issues, or claustrophobia. Also, since the cellar temperature hovers around 8-9°C, you’ll want to dress warmly. This experience is best suited for curious adults who enjoy a mix of history, geology, and good beer, and who are comfortable with some physical activity.

A Closer Look at the Experience

When we first hear about a volcanic beer cellar, it sparks curiosity. Mendig’s volcanic activity is a defining feature of the landscape, and it’s pretty neat to see how these natural forces are intertwined with local brewing. The tour begins in front of the Vulkan Shop, where groups gather before heading into the labyrinth of basalt rock. The meeting point, marked clearly with coordinates, makes it easy to find and adds a bit of anticipation.

Descending into the cellar involves walking down 153 steps—a steady, somewhat narrow staircase that leads you into the cool, dark depths. As you go down, it’s hard not to picture the volcanic eruptions that once reshaped this landscape. The extensive basalt quarries reveal the raw materials used in construction and brewing alike, providing a tangible connection to the earth’s power.

Once underground, the environment is quiet but fascinating. The temperature remains steady around 8-9°C, which is perfect for storing beer but might feel a tad chilly if you’re unprepared. The atmosphere is almost primal, with the elemental forces of nature evident in the exposed basalt walls and the cavernous space. Visitors have commented that “the experience of being 30 meters below ground in such a historic setting really makes you appreciate the craft of brewing.”

Learning About Volcanic Influence and Brewing

One of the most engaging parts of the tour is understanding how the volcanic eruption of Lake Laach influenced the local brewing culture. Our guide explained that the volcanic basalt not only provided the building materials but also contributed to the terroir—an influence that gives Mendig’s beers a unique character.

You’ll hear stories about how, once the refrigerator was invented in 1876, brewing could happen year-round, but the historic basalt cellars persisted as a special way to store high-quality beers. The Bourbon Barrel Doppelbock is stored in authentic bourbon barrels from the USA, bringing a distinctive flavor profile and making this beer a bit of a legend—Germany’s best craft beer of 2017, no less.

Authentic Beer Tasting and Storage

What sets this tour apart is the chance to see and taste a rare craft beer stored in its original barrels. The bourbon barrels add a smoky, vanilla undertone that’s quite different from typical German beers. Some reviews mention that the beer’s flavor is “complex and well-crafted,” thanks to the unique storage method.

While the tour itself doesn’t include a tasting session as part of the standard experience, visitors are often left with an appreciation for the process and the finished product. If you’re into craft beers, this part of the tour really hits the mark, especially since the barrels are from the USA, adding an international twist.

Physical and Practical Considerations

A few reviews have pointed out that the descent into the cellar can be physically demanding. Climbing 153 steps isn’t a walk in the park for everyone, particularly if you have circulation, walking, or breathing issues. It’s essential to wear sturdy, closed-toe shoes because the floors are uneven and rocky in places. The need for warm clothing is also stressed because the cellar’s cool environment can be quite brisk.

The tour is approximately one hour long, making it a manageable activity for most travelers. It’s worth noting that drinking alcohol during the tour itself isn’t allowed—this is more about learning and appreciating the context of the beer storage rather than a tasting party.
