Penicillium Roqueforti

Penicillium roqueforti is the mold required to make Blue Cheese

About This Product


Make hundreds of your own blue cheese at home with a properly stored packet of Penicillium Roqueforti.

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.

Vegans: Choose the PRB6 strain. The other strains contain lactose and are not Vegan.  ORDER LARGE Bottle PRB6 on this separate link, or Small Bottle PRB6 with this link.

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

  • PS has a medium-fast growth rate, a mild blue taste and a blue-green color. Sometimes used in conjunction with penicillium candidum (especially HP6).
  • 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. 

Makes up to 50 Blue cheeses in 4in (11cm) sizes with each 2.5 dose packet.
