The cheese in the OP is Västerbotten, named after the county in northern Sweden and generally considered the finest mainstream cheese. It's only made in a single place and is extremely tasty. I use it all the time for grilled sandwiches and such, but it's too expensive to make pizza with it.
If you do, it's legendary though.
Västerbottenost (cheese) is amazing. Put it on a pizza and consequences will never again be the same.
