I wasn't aware, until I read in the latest 'Descent' Cavers magazine(243) on the Mines and Mining page, titled: Rich savoury notes, about this 'Welsh Slate Cavern Aged Cheddar'.
An extract from the text reads; 'it had been matured for fourteen months in Llechwedd Slate Caverns at Blaenau Ffestiniog in North Wales before being sold on'.
The supermarket where you can purchase this cheese is mentioned in 'Descent', suffice to say, one of the big four!
Have I tried the cheese? Yes, however it is a strong cheese!
Also available at same supermarket is 'Wookey Hole Cave Aged Cheddar' and before you ask, I have tried that as well.
With a cheesy grin,
Spires. 😉
