A Forgotten Brewery Cave - Remembered.....and Now Sealed.

Leinenkugel's brewery.  No, not the one in Chippewa Falls.  The family had lots of branches.  This establishment was run by Henry Leinenkugel and was on the banks of Half Moon Lake in Eau Claire.

A brief history of the brewery.

Like the Jacob Leinenkugel brewery up in Chippewa Falls, this one started in 1867.  It was actually run by Henry Sr. and his son, Henry Jr.  It got off to a good start, and for a time was the top producing brewery in Eau Claire.  But in 1876 Henry Jr. died, and as his father had by that point retired, the enterprise was taken over by Caroline, wife of the Departed.  Things got difficult.  Their production dropped in half, and their credit ratings were not positive.

A partnership of Frase and Lissack bought the brewery and did their best for a couple of years, but also failed.  The next owners were Carstens and Hartwig, who with additional partners ran the place until it burned down in July of 1885.  It was never rebuilt.

The newpaper article that described the fire mentions that the beer in the underground vaults was preserved.  So lets visit these "vaults".  Or actually, revisit them, as this is one of the brewery caves I have previously shown but not given a location.

While not generally known, the location did attract the usual unwelcome visitors.....

That picture was from a later visit.  The first time I crawled in it looked like a bit more of a cozy hangout for neighbors.

Yes, crawled in.  The entrance had been sealed at least twice in the past.  

Here's what the entrance looked like until recently.

Summer of 2025.

I can actually trace the history of the cave since 1885 in some detail.  I've seen a photo circa 1900 that shows the remnants of what would have been the original entrance.  It was of course a straight run out, so that beer could be hauled out and ice hauled in.  This was about the time period in which the local paper describes it as being a hideout for local delinquents who were stealing things from cabins around the lake.  

In the 20th century it was used for a time by Silver Springs, a company now known for various mustard and horseradish products, but back then they had a larger line of veggies, some of which required cold storage.  The nice cement floors and the remnants of an electrical system must date to this era.

Times more recent have been troubled.  Eau Claire has a significant problem with homelessness.  And brewery caves naturally attract people with nowhere else to be.  Both this cave and "The Cave of the Mad Poetess" have had semi permanent residents in recent years.  There have been issues.  Danger of people being hurt.  I've heard there was a sexual assault.  It's worth noting that this cave is adjacent to a public park/beach.

So the "other" Leinenkugel cave has been sealed off.  Its the right call.  Everything is still down there and now preserved, perhaps for some happy day when history is appreciated more and the troubles of the world are fewer.

After I took the last photo, Hank and I walked past the beach.  It was about 9am and a homeless guy was sleeping on the ground next to the beach house.
