The name 'schmeer case' doesn't ring a bell, however my guess would be that farm people made their own version of a runny cheese that smelled a lot like dirty socks. Mom would hang it on the clothes line until it 'cured' and not one bird ever came to sit on that line until she took it off. A very soft brie reminds me of her cheese.

Sounds close, Mom made hers in a large crock, which she stored in the barn...you could not smell it there. Sure it was with the fresh hay but in the barn none the less. It was a cured cottage cheese so might be very close to what your mother made...no bird or self respecting mouse would have come near mom's crock.
