Last Monday my latest batch of epoisses style cheese reached 60 days. This is the minimum time required by federal law that cheeses made from unpasteurized milk have to be aged before they can be sold. Although I am not selling any cheese because they are not produced in a licensed facility, I am in the process of setting up a small creamery. I am toying with the idea of producing a raw milk epoisses style cheese when I have the plant set up. As far as I know there is no such cheese available on the American market. All the imported epoisses are produced from pasteurized milk and I don't know of any domestic produced cheese in this style.
This batch of epoisses held up remarkably well up to the the 60 days mark. I had moved the cheeses from aging cave at around 45 days, wrapped them and put them in a refrigerator at about 42 degree F. After 60 days they weren't ammoniated at all and when properly stored I think they can easily last for at least another two weeks before becoming too ripe.
