Penicillium Roqueforti

Short Description:
Penicillium roqueforti is a culture used when making blue cheese. The three different strains available provide different textures and flavors when making your own blue cheese.

Product Description

Make hundreds of your own blue cheese at home with a properly stored packet of Penicillium Roqueforti. The strains have received DVI-Direct Vat Inoculation. Each direct set freeze-dried packet comes in 10 doses or 2.5 doses (repackaged) for easy hobby and home usage without the hefty commercial price tag.

Each of the three strains of Penicillium Roqueforti culture creates a different texture and taste in the penicillium cheese. Choose between the following:

  • PRB6 Strain is a liquid form of Penicillium Roqueforti that has a blue-green color, grows fast and a strong blue flavor. For commercial usage, use 2 doses for every 1000 liters of milk (2200 lbs.). For hobby usage, one drop for every gallon of milk is required. Dose size: PRB6 bottle must be used. This strain is Vegan. Expiration date: These bottles come from France and they put the DAY first, then the MONTH and then the YEAR. After this date, the product does not stop working or 'expire'. If stored properly, it will be viable for a long time after the date listed.
  • PA Strain has a piquant aroma, extended shelf life, medium-fast growing rate and slightly tough consistency. Used to make mild Blue cheeses such as Roquefort and is a great choice for hard blue cheeses. 
  • PV Strain grows quickly and has a creamy consistency, strong tolerance to salt and a piquant aroma. Make Blue cheese including Roquefort, strong Gorgonzola and Danablu. 
  • PJ Strain has an expected blue flavor, middle-green color and grows fast. 

Make approximately 300 Blue cheeses in 4in (11cm) sizes with each 2.5 dose packet. The standard dose rate is 1/32nd-1/16th tsp. (.14g-.07g) for every 1-5 gal (3.75litres-19liters) of milk. The strains are non-GMO, contain lactose and Kosher except PRB6, which is not Kosher.

Follow the steps of regular cheese making to make blue cheese but add in one crucial step to the process: needling. Pierce the cheese to introduce air to feed the penicillium cultures and create the famous blue veins. Blue cheese making culture and a blue cheese making kit may help you get started making your favorite blue cheese. Work with Penicillium Roqueforti vegan culture to perfect your own favorite blue cheese at home for your taste buds.

All strains are non-gmo. PR86 is not Kosher

    Hi Steve,
    I appreciate your reacting so fast and so positively pro-active to my earlier critique.

  3. good product but lacks important info

    Posted by Unknown on 5th Mar 2017

    Since this is a rather expensive product, I appreciated finding it in a small size package. The mold - to my surprise - came in a double Ziploc, which looked very different from the misleading larger size packaging in your pictures. Moreover, it did not provide any info about production date nor best before date nor lot #, etc. Not very professional. That said, my aging Fourme d'Ambert is showing blue. Note from Steve/TheCheeseMaker: We take reviews seriously, wanting to always improve our service. We have now added the photos of the smaller package suitable for the hobbyist cheesemakers. Since this type of product only comes in the larger size. We repackage it for our customers at a much lower cost. And you'll only need a very very small amount, thus we include a usage rate on the packets. The repackaging doesn't allow a Lot number or date of mfg, yet you can be assured all our inoculants are very fresh and we'll never offer any outdated ingredients.

  4. Storage

    Posted by Unknown on 6th Feb 2017

    Is there any way to store it in a spray?
    Note from Steve: this type of mold is best stored dry in a sealed container with little air and in your freezer. You can dissolve a small amount in a little clean water, allow for the mold to dissolve well before spraying onto your cheese.

  5. Worked well

    First time making blue cheese. This stuff grew really easily and you only need a little bit.
