Christie,
I’m jealous. I’d love to have an Amish coop near me. We have a few Mennonites in the area, but they are more modern - they even buy store milk!
The salt rub is just about essential to prevent mold over the course of aging - especially a long age with a parm, or a sharp cheddar. And I firmly believe that vacuum sealing is the way to go. I’ve done about 400, and only had a couple that lost their seal. Also, you don’t have to monitor the humidity either.
Love that Havarti! It’s a great, mild cheese; and I get lots of people that want it, along with Gouda.
Have you been at it long enough to have tried some of your own?
