Hi DeepSix/Jason
I searched on internet and see that
Yancey's Fancy is a Corfu, New York State, USA based artisan cheese maker and that
Bergenost is one of their products.
QUESTION 1
I could find no other reference to that named cheese so assume it is their own brand name, Wikipedia
says the same.
QUESTION 2
Yancey's Fancy website has no info on their Bergenost other than the package labelling, image attached below. The label says it's "A Buttery Triple Cream Norwegian Style Cheese" whose listed ingredients are "pasteurized milk, cream, cultures, salt, and enzymes". Personally I've never seen or heard of this cheese, so sorry, can't help on knowing a similar type of cheese. Hope this info helps others.
