Cheese produced at Heartland Creamery in Missouri is being aged at Mark Twain Cave, before it is packaged at its origin, with first such moves initiated during the Memorial Day weekend.
According to the firm, the cave where the cheese aged has a perfect and constant temperature of 52 degrees, reported hannibal.net.
Cheese is left to age for 31 days before being transported back to Heartland for packaging, and personnel at the cave do not handle the cheese being aged.
The cave-aged cheese is sold only at the Mark Twain Cave in Hannibal, and it features at 192 stores across the US.
Several cow and goat cheese flavors are available, which reportedly sell well at the cave.
