    This mold powder will produce a white to cream color surface and it plays a significant role in the ripening process for surface ripened cheese of the soft ripened or washed rind types. It greatly influences the appearance, structure and flavor of Brie and Camembert, along with a variety of goat cheeses. It also helps prevent the skin from slipping off of your cheese. In red smear cheeses it helps neutralize the surface of the cheese and stimulates the development of desired, acid-sensitive flora such as P.candidum.
    Geotrichum can also be used in conjunction with Brevibacterium linens to create the right conditions for the formation of the surface smear on washed rind cheeses.

    CONTAINS: Geotrichum Candidum (GEO17)

    SIZE: 10D

    BRAND: Danisco Choozit

    USAGE: Add a pinch (approx. 1/16th teaspoon) to each 2 gallons of milk at the same time as adding culture. Use in conjunction with P.Candidum, in a ratio of 1 part Geotrichum to 4 or 5 parts P. Candidum.

    For larger batches of 50 gallons or more, it is more economical to add the mold powder to 1qt of water with 1/2 teaspoon salt in an atomizer. Rehydrate for 16 hours and then spray on the new cheese surface. Store the atomizer in the refrigerator and it will keep for up to 60 days.
    When spraying onto the surface, the moisture, temperature, and air circulation must be strictly monitored to avoid wet surfaces.

    STORAGE: Store in the freezer.

    NOTE: This product is Certified Kosher OU. Kosher certificate available upon request.

    We recommend using our Mini Measuring Spoon Set to help in adding the correct amount of starter culture.

    Q: I have been experimenting with St Maure Goat Cheese and the likes using P. Candidum and Geotrichum Candidum. The white mold starts fine but then seems to form a skin and separates from the cheese. How would I get the skin to stick better to form a better rind? I keep the cheese in their own plastic boxes. I have refrigeration at 55F, 40 and below, and room temp around 72F.

    A: The problem is not the skin, it is from too much residual moisture in the early curd, caused by one or all of the following:

    • In the early part of the process you are not setting your milk firm enough and so it becomes difficult to drain.
    • You are not draining them well enough before drying off (this can be a problem with late lactation milk). Remember that the curd will lose 10-20% moisture in the drain/dry phase.
    • You are not drying enough or fast enough before the mold starts to form. Using a fan and keeping the relative humidity below 75-80% may help with this.

    What is happening is that your mold begins to form before the cheese has dried down to it's desired size. Once the mold forms its jacket and the curd continues to shrink due to moisture loss, the cheese becomes a size too small for it's coat. Another problem here is that this is where protein breakdown happens the fastest with too much moisture and can result in a runny paste, which is why the skin will fall away. These cheeses generally ripen very early near the surface while the inside will be chalky and firm.

    In a nutshell, get the moisture drained and the surface dried as quickly as possible!

    Brie - a traditional French style
    the goal of making this cheese is to develop the proper curd to prepare the cheese surface for the beautiful white coat that makes this cheese so unique.

    The following recipe will produce very nice brie from 2 gallons of milk for the home cheese maker.
    If using the smaller molds listed below, the following can be cut in half for 2 small cheeses.

    What you will need :


    - 1 Pack of Rick's Mesophilic C101 culture OR 1/4 teaspoon of MM100
    The next 2 cultures are surface ripening molds and should be added to the milk when culture is added.
    - Geotrichum C7 - just a pinch (about 1/32 tsp.)
    - P.candidum C8 - 1/16 tsp.
    - Calcium Chloride 1/4 tsp- If having problems with forming a good curd using cold stored milk then this can help. We do not use this with fresh milk.


    1ml or slightly less than 1/4 tsp single strength rennet.

    Molds for draining the curd:
    You have 2 options here

    (1) 4 Smaller 4" Bries
    using 4 of our M7 Molds.
    A large single Brie
    1- 7inch brie using the plastic strip molds shown in the photographs.
    these were simply made from food grade plastic strips. The larger one is 1/4" stock cut to 6inch width and the smaller is 1/8" cut to 1.5" width. The strips are formed into a circle by placing in very hot water and formed into the loop before plunging into very cold water. The loop is tightened and held with a chord and slip knot.

    Salt: 4 tsp. of a coarse cheese salt

    Draining Mats: 2 for each mold

    A Solid board for under each draining mat. They go under the mats above (this will make your turning so much easier).

    A knife and ladle or spoon to transfer curds


    Heat the milk to 90F and add all cultures above to the milk
    Stir the cultures into the milk well and rest at 90F for 30 min.

    Add the rennet and stir into milk for 1 minute then allow the milk to sit quiet for 90 minutes. The milk will begin to thicken at 15-20 minutes but we leave the milk much longer then other cheeses to produce a higher moisture cheese for ripening.

    During the wait, Sanitize all molds, draining mats, and turning boards. I do this here in water simmering at about 145-160.
    Prepare the molds by laying down a turning board, then the draining mat, and finally the mold on top.

    At 90 minutes your curd should be very firm and ready to transfer to molds.
    little to no curd cutting is involved.

    Traditionally this was done without cutting the curd mass. If using a larger mold as shown in photos no cutting of the curd is need. Transfer the curds with a large slotted spoon by taking thin layers (1/2") from the curd mass.

    If using the smaller molds, the curd mass should be cut into 1" cubes and stirred briefly to allow the full curd to fit into the 4 molds. The reason for this is that these molds are produced for the industry which cuts larger curd masses to facilitate a quicker production. These molds should be filed in a "round robin" manner to allow the curds to settle briefly and whey to drain before the next addition. If all of the curd does not fit when the molds are full simply wait a few minutes and the curd will settle, then add the rest.

    Allow the curds to settle and drain keeping the draining space at 68-74F (warmer or cooler will cause problems with the resulting cheese).
    To assure complete draining the cheese will need to be turned in the molds. this is done by placing a second draining mat on top followed by another turning board. Then carefully lift the entire assembly carefully and with one hand on top and the other on the bottom flip the cheese over quickly.
    For the smaller cheese it is best to make the first turn shortly after the curd is ladled (10-20 min). This will keep it from falling too far in the mold and breaking.
    For the larger cheese using the second plastic strip mold (1.5"), allow the entire cheese to drain down to about 1.5" then loosely place the short hoop around the larger form and remove the 6"form. Then tighten the shorter form, place the second draining mat and board on top, and turn this cheese over.

    The cheese will drain down to about 1/3 the original curd height and this may take 18-24 hours (or longer) for completion. During this time flip the cheese in their forms several times to make sure the draining is even. The cheese will become firmer and the turning easier as it drains. The taste of the whey at this point should have a very noticeable acidity to it compared to that first running out during draining. It is a good practice to taste the whey and curds throughout the process for future reference.

    At this point you will be into the second day and as the whey drainage slows it is time to add salt. Leave the cheese in the molds for this.
    For the smaller cheeses 1/2 tsp. per cheese spread evenly over each surface and for the larger cheese 2 tsp. Allow the salt to dissolve and be absorbed by the cheese. Wait 8-12 hours then flip the cheese and apply the second dose of salt in the same manner. The salt will cause more whey to run off and this will also taste very salty.

    Allow the cheese to dry off for another day until you see no free moisture on the surface.

    If proper draining and drying is not done before the molds begin to grow, problems with rapid protein breakdown and other undesirable molds may become a problem.

    It is now time to allow the cheese to develop the white coat. The proper storage condition for this will be 52-56F and 90-95% moisture. They should also be placed on draining mats to allow air to reach the underside. The cheese also needs to be turned 1-2 times per day to keep the molds from growing into the mats and tearing away the surface when moving.
    If aging in plastic boxes with covers make sure the moisture does not drip onto the cheese and be sure to wipe any free moisture from the lid and box when turning.

    At about 10-15 days after making this cheese, you should notice a good white coat developing. It is OK to pat this down when turning. If the coat has formed well it is time to slow down the process. Move the cheese to a cooler area of about 40-44F to allow the softening of the cheese in an even manner. The cheese is ripe when it feels soft on pressing. This should take 30-45 days and the final ripeness depends largely on personal taste. When the cheese is cut through you will notice a creamy layer near the outside and a white center. This ratio can be controlled by aging time and temperature.

    Trouble Shooting:
    blue mold = too moist (insufficient draining and/or drying)
    black mold (Mucor) = insufficient salt or too high moisture
    red/pink mold = insufficient drying or too high moisture in aging area
    runny liquid under surface = insufficient draining
    dark dry areas = excessive drying
    no white mold = excessive drying or too cold

    The curd will have a thin layer of whey covering it and separate from the vat when ready to cut.The molds are shown with
    short strips in place
    to be tightened after draining.
    The curd is not cut but carefully ladled in thin layers into the sanitized and preheated molds...
    ...that have been prepared and
    placed on bamboo mat. At this point the curd is still quite sweet.
    The molds are filled in succession slowly, a few ladlefuls at a time.They now need to set quietly
    and drain in a draft free area...
    ...with a steady temp overnight.
    During this time our
    final acidity develops
    By the next morning they will have drained down to 1/3 original height.
    The tall inner hoop may now be loosened and removed......and the shorter hoop is now tightened......so that it can be flipped over without breaking.
    The original mat can now be gently removed leaving it's imprint.
    The flipping continues for the next several hours and dry salting the surfaces can be started......as soon as the curd
    dries down and free whey
    is no longer an issue.
    The drained and salted cheese is now ready to be moved to a space with moderate air flow...
    ...and the drying off continues
    for the next day or so,
    keeping the temp at 65F.
    Following the drying off
    move to 54F-90% ,
    where the white surface will
    begin to develop at day 5...
    ...and continue through
    about day 10-12 when
    they can be wrapped...
    ...and moved to a
    moister and cooler space
    (38-42F.. 95-97% humidity)...
    ...where the white surface begins to die back and the red/yellow streaks begin to show.

    At about 4-6 weeks the curd should have ripened
    to at least the half way point
    and it is ready to eat.
    You can try it at an earlier stage when the taste is quite fresh and sharp......or wait until it really develops some character and the flavor deepens and shows the true flavors of the milk.

    Works Great!

    Always reliable for my camembert!



    Does the Job

    First try I made great brie with this product, and the recipe from this website. The mold coating was more robust and grew more quickly than expected.

    Was shipped out very quickly and came in a nice package. The mold worked great and formed a very nice skin on my cheese. A little more expensive than other cultures but you get a lot and it will definitely last me a while.




    I use 1/64 tsp for 2 galons batch. So 1 pack will last a long long time.

    I love making soft cheese or semi hard cheese using geotrichum, so far I have used it on camemberts, bries, mont d'Or and triple cream cheeses. Next I will make butterkase and Bel paese with it.

    A little goes a long way

    I was a bit shocked at the price, but a little goes a looooong way.

    Worked wonderfully in my brie cheese.

    excellent value

    I have to say, I was skeptical about this mold because it was so expensive. However, I wanted my camembert to be spectacular. I bought it and saw that you only need a hint of it in each batch, like 3-4 speckles per gallon. I was again skeptical.

    2 months later with delicious cheese with skin that didn't slip off, I am so impressed with the quality and value of this culture. I could essentially make thousands of cheeses with this since you only need so little.

    I would recommend the store to make a smaller pack perhaps that's more approachable?

    I've only used this once so far to make some Butterkasse. I was so excited to see that characteristic white fluff start to develop on the outside! I can't wait to try it in a few weeks! It comes in such a large quantity, I hope I can use it all before it gets too old!

    professional results

    I found this product to be easy to use. It can be used along with p Candidium to help with slip rind. It works great with my goat cheese


    From: NorCal


    According to suggestion I used this in conjunction with P.candidum on an otherwise benign goat cheese. The aim was for some kind of brie. I blew the proportions, gave it as much as P.candidum. The result was indeed exuberant growth of P.candidum and PUNGENCY in my cheese fridge. Ripening happened quite virulently fast, within just over a week the entire cheeses were runny... you could cut them open and pour them out. Fine tasting cheese but less than ideal to my nose. And a bit more difficult to handle once it liquefies.

    NB don't let the cheese loaves touch each other. The rinds will join, tear on separation and therefore a leak!
