Cultures

Cultures are bacteria naturally found in milk and also added at the first stage of cheesemaking. Once added the culture start to feed off the milk sugar's (lactose) and starts to produce lactic acid. The more acidic the milk turns, the easier it coagulates for better curds that are prone to expel easier. They can also determine the overall flavour and texture during maturation. Milk will naturally acidify if left at room temperature as it contains bacteria, teh idea of culture is to speed things up a little. The 2 main cultures available are

  • Mesophilic - withstand temperature maximum of 30 C/102 F (buttermilk)
  • Thermophilic - withstand temperature maximum of 55 C/132 F (yogurt)
TYPES

Flora Danica-Mesophilic Starter

(LL) Lactococcus lactis subsp. lactis
(LLC) Lactococcus lactis subsp. cremoris
(LLD) Lactococcus lactis subsp. lactis biovar diacetylactis
(LMC) Leuconostoc mesenteroides subsp. cremoris

For making goats milk cheese, Havarti, Baby Swiss, Gouda, Edam, Blue, Goats Milk Cheese, buttermilk/sour cream, cream cheese, cottage cheese, Crème Fraiche, cultured butter and other fresh cheeses. Use 1/8 tsp. per 1 gallon(3.7liters), 1/4 tsp. per 2-5 gallons(7.5-18.9 liters) 1/2 tsp. per 5-10 gallons(18.9-38 liters). Allow 18-20 min. at 70f (21c) to acidify to a pH of 4.60-4.70. Can be used to make Camembert/Brie but you must use another Mesophilic starter culture also.Using Flora Danica will give the cheese a buttery flavor.

Proprionibacteria-
(25 grams)
Must be used along with a Thermophilic culture.

Proprionibacteria freudenreichii subsp. shermanii
(freeze-dried direct set/DVI-Direct Vat Innoculation)

For the maturation and eye formation of Swiss type cheeses such as Emmental, Gruyere, Jarlsberg, Compte, Tilsit and Appenzeller. Contribute greatly to the taste and aroma of these types of cheeses. This packet will work with 265 gal.(1000 liters) of milk. Use 1/8 tsp. (.62g) for two gallons(7.5 liters) of milk.
