I bought about 8 blocks last week to try smoking cheese for the first time. Smoked for about 3.5 hrs with apple chips and pellets in my MES 30, using my Masterbuilt external smoke generator set-up. I cycled the heat on every so often and stayed between about 40-60 degrees, ambient temp was 30. Vacuum sealed everything, I will check on the first piece in about a month. I did some Cabot Vermont Extra Sharp, Seriously Sharp, Store brands: mild cheddar, sharp cheddar, Monterey Jack, pepper jack, and Gouda.
