Just as an update, I read Brie's message on another thread about using two mini-fridges to keep the white and blue molds separate. That's a really good idea! I've only tried the blue mold so far, but I have some white and red mold too, hoping to work my way up to Epoisses. (So far I've made Feta, Cheddar, Pepper Jack, Gouda, Emmental, Gorgonzola, and Whey Ricotta.) So we got two mini-fridges at Walmart for less than the chest freezer would have cost. I'm going to celebrate by making a Blue Gouda.
