    • If you use only a partial of the envelope, can the cut edge of the envelope be rolled up and stored in a zip bag in the freezer for future use? Does the appearance change if the molds are not good any longer?
      Thank you,
    • Yes you can save the unused portion by folding the envelope and sealing it in a zippered freezer bag. Remove excess air and store in the freezer for up to 2 years. You will likely not notice a change in appearance if the Penicillium Roqueforti is no longer active.

    • Hi, I am vegan, and I was wondering if any animal products are used to make your cultures. I know it is entirely possible to obtain this culture without dairy, unfortunately I am unable to find source information for most cultures on any product website. Please let me know, I would love to begin experimenting with it! Thanks, Kaylin
    • The Penicillium Roqueforti cultures do contain a small amount of milk.

    • I have gone vegan-gluten free. I am looking for cultures to make similar cheeses to put in my gluten free vegan cooking.
      Can this culture grow in soy milk, rice milk or almond milk to make a similar cheese?
    • In short...not really. The problem is that nut milks are mostly carbohydrates and have very few solids (protein and fats) so they will ferment, but they won't separate. You can make a very nice soft cheese from coconut yogurt or kefir, though. Just use our dairy kefir grains (or a yogurt culture) and drain the whey. Super easy, and it tastes a lot like cream cheese.
