Following the link provided, their advertisement states that the cheese is from pasteurized milk. So it could be exported...
It also says the cheese is made from the milk of Ayrshires and Holsteins (cows).
My wife's line are Thompsons that we have traced back to Ayrshire, Scotland in 1691.
I make cheese at home, so this may be an interesting project for me; make some cheese that has ties back to predecessors...
As a side note, it gets hot in the kitchen when I brew beer and make cheese, so I am usually kilted for comfort when doing so. Mtn Hardware Elkommando utility kilt is nylon canvas and cleans up easy.
