The original cave was carved in the 1850s for Fleckentstein Brewing Co. founded by German immigrants Ernst & Gottfried Fleckenstein. Prior to modern day refrigeration, beer caves were commonly used to store the beer at cooler temperatures. Fleckenstein operated here until 1919 when Prohibition was imposed. The caves did not reopen under Fleckenstein Brewing Co.
In the 1930s, a cheese maker by the name of Felix Frederiksen traveled to Minnesota in search of St. Peter Sandstone, geologically rare across the nation but abudant in Minnesota as a result of the last glacial age. Felix found the abandoned caves in Faribault and set up shop for making the first American blue cheese. Prior to the 1930s, all of the blue cheese consumed in the United States was imported from Europe. WWII put constraints on importation, so Felix was in good business. He named his cheese "AmaBlu" taking the 'ama' from Latin for "I love" and 'blu' as the international spelling of blue. Many more caves were hollowed between the 1930s and 1970s by his company Treasure Cave, Inc.
Treasure Cave was closed down at this location in the 1990s by a company that bought the caves and then moved production to a conventional cheese making facility in another state.
Faribault Dairy Company, Inc. (now known as Caves of Faribault®) was founded in June, 2001 to revitalize the caves after an eight-year dormancy. American-made AmaBlu® premium blue cheese from the famous St. Peter Sandstone caves was back in the marketplace. AmaBlu® Gorgonzola and St. Pete's Select® super-premium blue cheese came to follow, forming a triumverate of hand-made, cave-aged, internationally acclaimed blue cheeses.
