  • Salt (for flavor and preservation)
  • Calcium chloride (optional, to improve curd formation in pasteurized milk, usually not needed with raw milk)

Step-by-Step Process to Make Cheese from Raw Milk

The cheese-making process involves multiple stages to transform raw milk into a solid curd that can be aged or consumed fresh. Each step requires careful temperature control and timing.

Heating the Milk:
Begin by pouring raw milk into the stainless steel pot. Heat it slowly to the desired temperature, typically between 86°F to 95°F (30°C to 35°C), depending on the cheese variety. Use the thermometer to monitor temperature consistently.

Adding Starter Culture:
Once the milk reaches the target temperature, sprinkle the starter culture evenly across the surface. Allow it to rehydrate for 1 to 2 minutes before stirring gently into the milk. The culture will acidify the milk, crucial for curd formation and flavor development.

Ripening the Milk:
Maintain the milk at the set temperature for 30 to 60 minutes to let the bacteria multiply and lower the pH. This stage is called “ripening” and prepares the milk for coagulation.

Adding Rennet:
Dilute the rennet in a small amount of cool, non-chlorinated water. Stir the diluted rennet gently into the milk for about 30 seconds. Then stop stirring and let the milk sit undisturbed to coagulate, usually 30 to 60 minutes. The milk should form a firm curd that breaks cleanly when cut.

Cutting the Curd:
Using a long knife, cut the curd into small cubes (approximately 1/2 inch or 1.3 cm) to allow whey to separate. The size of the cut curd influences the moisture content of the final cheese.

Cooking and Stirring the Curd:
Gradually heat the curds by increasing the temperature by 2°F to 4°F (1°C to 2°C) over 30 minutes while gently stirring. This process helps expel whey and firms up the curds.

Draining the Whey:
Pour the curds and whey into a colander lined with cheesecloth. Allow the whey to drain naturally or apply gentle pressure to speed the process, depending on the cheese type.

Salting and Pressing the Cheese

Salting is essential for flavor, preservation, and controlling moisture content. Depending on the cheese style, salt may be added directly to the curds or applied externally.

  • Dry salting: Sprinkle salt over the curds before pressing.
  • Brining: Soak the formed cheese in a saltwater solution after pressing.

Pressing shapes the cheese and expels additional whey. Use a cheese press or apply a weighted plate over the cheese mold.

Cheese Type Pressing Time Pressing Weight Salt Application Method
Fresh Cheese (e.g., Ricotta) Minimal or none None Mixed in curds
Semi-Hard Cheese (e.g., Cheddar) 6-12 hours 10-20 lbs (4.5-9 kg) Dry salting before pressing
Hard Cheese (e.g., Parmesan) 12-24 hours 20-50 lbs (9-23 kg) Brining after pressing

Aging and Storage Considerations

Many cheeses benefit from aging, also known as affinage, which develops texture and flavor complexity. Aging requires controlled temperature, humidity, and ventilation.

  • Ideal aging temperature: 50°F to 55°F (10°C to 13°C)
  • Relative humidity: 80% to 90%
  • Regular turning: To ensure even moisture distribution and prevent mold buildup
  • Monitoring for unwanted molds or defects

Fresh cheeses can be consumed immediately or stored refrigerated for several days. Hard and semi-hard cheeses can be aged from a few weeks to several months or years depending on the recipe.

Proper packaging after aging, such as wax coating or vacuum sealing, helps maintain quality during storage. Always label cheeses with the date of production and aging duration to track progress.

Maintaining sanitary conditions throughout the process, especially when working with raw milk, is critical to avoid contamination and ensure a safe final product.

Preparing Raw Milk for Cheese Making

To make cheese from raw milk, it is crucial to begin with properly handled and prepared milk to ensure safety and quality. Raw milk contains natural bacteria and enzymes that contribute to cheese flavor development but also requires careful handling.

Steps for preparing raw milk:

  • Source high-quality raw milk: Obtain milk from healthy animals that have been milked hygienically. Freshness is key; use the milk within 24 hours of collection.
  • Filter the milk: Remove any debris or hair by passing the milk through a fine mesh or cheesecloth.
  • Standardize the milk (optional): Adjust fat content if desired by skimming cream or adding cream to achieve consistent cheese texture.
  • Warm the milk: Slowly heat the raw milk to the target temperature for your cheese type, typically between 30°C and 37°C (86°F to 99°F). Use a double boiler or a stainless steel pot over low heat to avoid scorching.
  • Check milk acidity: Measure the pH or titratable acidity. Ideal starting pH for most cheeses ranges from 6.5 to 6.8.
  • Add starter cultures: Introduce specific bacterial cultures to acidify the milk and develop flavor. Even though raw milk contains native bacteria, starter cultures help control fermentation.

Coagulating the Milk

Coagulation transforms liquid milk into a gel-like curd by causing milk proteins (casein) to clump together. This is essential for cheese formation.

Key elements of coagulation:

  • Rennet addition: Add animal, vegetable, or microbial rennet to the warmed milk after starter cultures have been incorporated and allowed to ripen (usually 30–60 minutes). Rennet contains enzymes that cleave casein proteins.
  • Ripening time: Allow the milk to rest undisturbed at the target temperature for 30 to 60 minutes, or until a firm curd forms. The curd should break cleanly when tested.
  • Temperature control: Maintain a consistent temperature during coagulation. Sudden temperature drops can lead to weak curds.

Cutting and Cooking the Curd

Once the curd has formed, it is cut to release whey and develop the desired cheese texture.

Cutting the curd:

  • Use a curd knife or long blade to cut the curd into uniform cubes, typically 1 to 2 cm in size, depending on cheese type.
  • Smaller curd size results in drier cheeses by releasing more whey.

Cooking the curd:

  • Slowly heat the curds while gently stirring to encourage further whey expulsion.
  • Cooking temperature and duration vary based on the cheese style; for example, hard cheeses may be cooked to 38–42°C (100–108°F) for 30–60 minutes.
  • Maintain gentle agitation to prevent curd clumping and uneven cooking.

Draining Whey and Molding the Cheese

After cooking, the curds must be separated from the whey and shaped.

Step Description Tips
Draining Pour the curds and whey into a cheesecloth-lined colander to separate the liquid whey. Save whey for other uses such as ricotta or animal feed.
Molding Transfer drained curds into cheese molds to shape the cheese. Use appropriate molds depending on cheese type; apply gentle pressure to compact the curds.
Pressing Apply pressure to expel additional whey and form a solid cheese block. Press for a few hours to several days, depending on cheese style and firmness desired.

Salting and Aging the Cheese

Salt enhances flavor, controls microbial growth, and aids in rind development. Aging develops texture and complex flavors.

Salting methods:

  • Dry salting: Rub salt directly onto the cheese surface or mix salt with curds before molding.
  • Brining: Soak cheese in a saltwater solution for several hours to days depending on cheese size.

Aging conditions:

  • Store cheese in a controlled environment with temperatures between 10°C and 15°C (50°F to 59°F) and humidity around 80–90%.
  • Turn the cheese regularly to ensure even aging and rind formation.
  • Aging duration varies widely from a few weeks to several months or years, depending on the cheese variety.
