Preparing and Handling Raw Milk for Cheesemaking
The quality of raw milk is paramount in producing high-quality raw milk cheese. Proper handling and preparation of the milk begin immediately after milking to preserve its natural enzymes and beneficial bacteria essential for flavor development and texture.
Fresh raw milk should be strained through a fine mesh or cheesecloth to remove any debris such as hair, dirt, or straw. This filtration step ensures that the milk is clean without applying heat or other treatments that could alter its microbial profile.
Temperature control is critical. Raw milk should be kept at around 38°F (3°C) if not used immediately, as this slows bacterial growth without killing the native microflora. Avoid refrigeration temperatures below 34°F (1°C) to prevent chilling injury to the milk’s enzymes and bacteria. If the milk is to be held for more than 24 hours, it is advisable to use it quickly or consider gentle warming to about 86°F (30°C) to reactivate bacterial activity before cheesemaking.
Adding Starter Cultures and Coagulants
Starter cultures are introduced to raw milk to encourage the growth of lactic acid bacteria, which acidify the milk and contribute to cheese flavor and texture. Although raw milk contains native bacteria, adding a commercial or traditional starter culture ensures consistent acidification and safety.
Common starter cultures include:
- Mesophilic cultures (e.g., Lactococcus lactis) for cheeses that mature at moderate temperatures.
- Thermophilic cultures (e.g., Streptococcus thermophilus) for cheeses requiring higher cooking temperatures.
The amount and type of starter depend on the cheese style and milk condition.
Coagulation is induced by adding rennet, an enzyme that causes casein proteins to form a gel-like curd. Both animal-derived and microbial rennets can be used; the choice affects flavor and texture subtly.
The addition sequence generally follows this order:
- Warm raw milk to the desired temperature (typically between 86°F and 95°F / 30°C to 35°C).
- Stir in starter culture evenly.
- Allow the milk to ripen for 30–60 minutes to develop acidity.
- Add rennet diluted in cool, non-chlorinated water.
- Stir gently for 1–2 minutes and allow curd formation for 30–45 minutes.
Cutting, Cooking, and Draining the Curd
Once the milk sets into a firm curd, it is cut to release whey. The size of the curd cubes influences moisture content and texture; smaller cubes expel more whey, resulting in harder cheese.
Cutting techniques:
- Use a long knife or curd harp to cut vertically and horizontally.
- Aim for uniform cubes, typically ½ to 1 inch (1.3 to 2.5 cm).
Cooking the curd involves gently heating and stirring to contract the curds and expel whey. Temperatures and times vary by cheese type but generally range between 102°F and 120°F (39°C to 49°C).
Key points:
- Stir slowly to prevent curds from matting.
- Gradually increase temperature over 30 minutes.
- Hold at target temperature to firm curds before draining.
Draining removes whey, either through draining tables, cheese molds, or cheesecloth-lined baskets. This step shapes the cheese and influences moisture retention.
Salting and Aging Processes
Salting is essential for flavor, texture, and preservation. It can be applied by:
- Dry salting: rubbing salt on the surface of the cheese.
- Brining: soaking cheese in a saltwater solution.
Salt concentration and duration depend on cheese type and size.
Aging (affinage) develops the cheese’s flavor and texture through microbial and enzymatic activity. Raw milk cheeses often require longer aging to ensure safety and flavor complexity.
Typical aging environment conditions include:
| Parameter | Optimal Range |
|---|---|
| Temperature | 50°F to 55°F (10°C to 13°C) |
| Humidity | 80% to 95% |
| Airflow | Moderate |
During aging, cheeses may be turned regularly, washed with brine or alcohol, or brushed to encourage specific rind development.
Safety Considerations in Raw Milk Cheese Production
Producing raw milk cheese involves inherent risks due to potential pathogens in unpasteurized milk. To mitigate these risks, it is crucial to:
- Source milk from healthy, well-managed herds.
- Maintain impeccable hygiene during milking and cheesemaking.
- Monitor pH levels closely during acidification; cheeses aged less than 60 days require strict control.
- Use established starter cultures to outcompete harmful bacteria.
- Adhere to local regulations regarding raw milk cheese production and aging periods.
Regular testing of milk and finished cheese for microbial contaminants is recommended to ensure consumer safety without compromising the unique characteristics of raw milk cheese.

Step-by-Step Process for Making Raw Milk Cheese
The transformation from raw milk to cheese involves controlled biochemical changes. Each phase requires attention to detail to maintain safety and achieve desired texture and flavor.
Milk Preparation and Acidification:
Begin by gently warming the raw milk to the target temperature, typically between 30°C and 37°C (86°F–99°F), depending on the cheese type. Add starter cultures evenly and allow the milk to ripen for 30 to 60 minutes. This acidification lowers pH, preparing the milk for coagulation.
Coagulation:
Add rennet to the acidified milk and stir gently. Let the mixture rest undisturbed for 30 to 60 minutes until a clean break in the curd forms. Temperature control during this phase is critical to ensure proper enzyme activity.
Cutting the Curd:
Using a long knife, cut the curd into small cubes, usually 1–2 cm in size. Smaller curds release whey more efficiently, influencing moisture content and texture.
Cooking and Stirring:
Gradually heat the curds to a higher temperature (often 38°C to 54°C) while stirring gently. This step helps expel whey and firms the curd. The exact temperature and duration vary according to cheese type.
Draining and Molding:
Transfer curds into cheesecloth-lined molds to drain whey. Depending on the cheese style, apply moderate pressure using a cheese press. The pressing time and pressure regulate moisture and texture.
Salting:
Salt can be applied by dry rubbing, mixing with curds, or brining. Salt controls microbial growth, enhances flavor, and assists rind formation.
Ripening:
Age the cheese in a controlled environment with regulated temperature (typically 8–15°C) and humidity (75–95%). Ripening duration ranges from days to months, during which biochemical transformations develop flavor and texture.
