  • Thermo B (10 grams/1 Dose or 100 grams/10 Doses):  A 10 gram/1 dose pouch makes up to 60 gallons/225 liters of milk into Italian type cheeses, such as Mozzarella, Romano, Parmigiano, Provalone and Grana (Reggiano).  A 100 gram/10 doses bottle would make up to 600 gallons/2,250 liters of milk into Italian style cheese.  Active ingredients: Streptococcus thermophilus, and Lactobacillus delbrueckii subsp. bulgaricus.   Other ingredients:  Lactose, ascorbic acid.
  • Thermo C (100 grams/1 Doses):  Makes up to 60 gallons/225 liters of milk into Swiss style cheeses, such as Gruyere, Jarlsberg and Emmental.  Active ingredients: Streptococcus thermophilus, Lactobacillus helveticus.  Other ingredients: Lactose, ascorbic acid.


TPM2, 50 UAT/Units:  A blended strain of Streptococcus Thermophilus for a soft stabilized cheese.  Excellent for Brie, Camembert or other soft stabilized cheeses.

  • TY947, 50 UAT/Units:  A blended strain of Streptococcus Thermophilus and Lactobacillus Bulgaricus.  This culture offers the benefits of making Pizza Style Cheese and Yogurt, all in one culture.


  • TA50 or TA52, 125 DCU:  The slow acidifying and very mild acid thermophilic culture.  This culture is a pure strain of Streptococcus Salivarius ssp Thermophilus. TA 50 series is good as lactic starter only or blended with other cultures as an adjunct.  This starter is frequently added to mesophilic cultures in making a stabilized bloomy rind cheese such as Camembert, Brie or Cambozola.
  • TA61, 125 DCU:  TA61 is a multipurpose thermophilic single-species culture of Streptococcus thermophilus. It can be used as a standalone starter or blended-in as an adjunct with other cultures. This culture has a medium to high acidity component and will remain a valid culture even at high heats of scalding at 53°C (127°F). This culture is commonly used for Mozzarella, Buratta, and Provolone, to Romano, Parmesan, Alpine Tomme styles, Emmental, Gruyère, Caciocavallo, Provolone, and many other styles.
