Overview of Cheese Cultures

There are a wide variety of cheese cultures to choose from. Most recipes call for a specific culture, but if you want to experiment a bit or create your own recipe, it helps to know what a cheese culture is and what type of cheese each culture is best-suited for.


What is a Cheese Culture? 

A cheese culture is a group of specific bacteria strains for making different cheeses. All cultures do the same basic work, rapidly raising the acidity of the milk by consuming the lactose (milk sugar) and converting it into lactic acid, which disables the already-present bacteria and helps the rennet or coagulant to set the cheese. Starter cultures also aid in development and preservation of the flavor and body of the cheese during cheesemaking and afterwards, in the aging process.


Culturing Temperature of Cheese Cultures

Cheese cultures can be grouped by the temperature range at which they work.

  • Mesophilic means medium-loving, indicating that a mesophilic culture will propagate best at temperatures up to 90ºF.
  • Thermophilic means heat-loving. This type of culture is added to milk heated to higher temperatures.

Specific Cheese Starter Cultures

We carry several cheese cultures that are designed for making one specific cheese. Some even contain rennet. Complete instructions are included with each of these starter cultures:


General Cheese Starter Cultures

We carry several cultures that have a more broad usage. These cultures contain several packets, so you can experiment with a variety of recipes from just one box of culture. Always consult your recipe, as other ingredients may be required for certain types of cheese.

  • Fresh Cheese Culture is an aromatic mesophilic culture used in producing soft cheeses such as Cottage Cheese, Neufchatel, Chevre. It can also used as the culture in flavorful aged cheese varieties such as Blue Cheese and Baby Swiss. 
  • Mesophilic Aromatic Type B is another versatile cheese culture with a buttery flavor. It is used for making sour cream and cultured butter, soft cheeses such as goat cheese, cream cheese and cottage cheese, and other specialty cheeses such as havarti and camembert.
  • Flora Danica Mesophilic Starter Culture also gives cheeses a buttery flavor. This culture is primarily used to make cheeses such as Gouda, Edam, Leerdam, Samsoe, and soft cheeses such as Lactic Cheeses, Camembert, and Blue Cheese.
  • MM Series Starter culture is used to make Brie, Camembert, havarti, gouda, edam, feta, blue cheese, chevre, and other buttery, open-textured cheeses.
  • RA22 Cheese Culture is a fast acidifying culture used for traditional cheddar and similar cheeses.


Thermophilic Cheese Starter Cultures

Thermophilic cheese cultures are used to make a variety of cheeses, sometimes in conjunction with a mesophilic culture.

  • Thermo B Cheese Culture is used for making Italian-style mozzarella, parmesan, romano, provolone, other Italian cheeses.
  • Thermo C Cheese Culture is also used for making Italian cheeses. It is also well sutied to making farmstead type cheeses, such as emmentaler, gruyere, swiss, and romano
  • Propioni Bacteria is used primarily for the eye formation, aroma, and flavor production in Swiss type cheeses.


Molds Used in Cheesemaking

Molds are responsible for giving some cheeses their specific flavor and texture. They are usually applied to the outside of the cheese where they form a crust.

  • Penicillium Camemberti white mold spores are used for making Camembert and Brie cheeses and are essential in the ripening process of cheeses with white surface mold.
  • Penicillium Roqueforti mold spores are used for making Blue Cheese and are essential in the ripening process.
