Preparing Raw Milk for Cheese Making

Before beginning the cheese-making process, it is essential to ensure that the raw milk is of high quality and properly handled. Raw milk, being unpasteurized, contains natural enzymes and bacteria that can influence the flavor and texture of the cheese. However, it also requires careful handling to avoid unwanted microbial contamination.

Start by filtering the raw milk to remove any debris or impurities. Use a clean, fine mesh sieve or cheesecloth. Then, gently warm the milk to the desired temperature for the specific cheese you are making. This temperature usually ranges between 30°C to 37°C (86°F to 99°F), depending on the type of cheese culture or rennet used.

Keep these points in mind:

  • Use a stainless steel or food-grade plastic pot to avoid any metallic reactions.
  • Stir the milk gently during warming to ensure even heat distribution.
  • Avoid overheating, as temperatures above 40°C (104°F) can kill beneficial bacteria and enzymes.

Adding Starter Cultures and Rennet

The next step involves introducing starter cultures and rennet to the raw milk. Starter cultures are specific bacteria strains that acidify the milk by converting lactose into lactic acid. This acidification is crucial for proper curd formation and flavor development.

Rennet is an enzyme that coagulates the milk proteins, forming the curd. There are different types of rennet, including animal-derived, microbial, and vegetable-based. The choice depends on the cheese variety and dietary preferences.

Guidelines for Adding Cultures and Rennet:

  • Starter Cultures:
  • Measure the recommended amount based on the volume of milk.
  • Sprinkle the culture evenly over the surface of the warmed milk and allow it to hydrate for a few minutes before stirring gently in.
  • Rennet:
  • Dilute rennet in cool, non-chlorinated water (usually 1:10 ratio) before adding.
  • Stir the diluted rennet gently into the milk for about 30 seconds.
  • Stop stirring and allow the milk to set undisturbed until a firm curd forms (usually 30-45 minutes).
Cheese Type Culture Temperature (°C) Rennet Amount (ml per 4L milk) Setting Time
Cheddar 32-33 1.5 35-45 minutes
Camembert 30-32 1.0 30-40 minutes
Feta 32-35 1.0 30-40 minutes
Paneer (acid-set) Boiling, then cooled N/A (acid coagulation) Immediate upon acid addition

Cutting and Cooking the Curd

Once the curd has set firmly, the next phase involves cutting the curd to release whey and begin the process of forming cheese texture. Use a long, thin knife or curd cutter to slice the curd into uniform cubes, typically about 1 to 2 cm in size. The size of the curd cubes influences moisture retention—smaller cubes lead to drier cheese.

After cutting, the curds are gently cooked by gradually raising the temperature while stirring. Cooking encourages further whey expulsion and firmer curd texture. The exact temperature and duration depend on the cheese style being produced.

Key points for cutting and cooking:

  • Cut the curd slowly and evenly to avoid breaking it into tiny pieces.
  • Stir gently during cooking to prevent curds from matting.
  • Increase temperature slowly, usually at a rate of 1°C every 5 minutes.
  • Cooking times range from 20 to 60 minutes, depending on desired cheese firmness.

Draining and Pressing the Cheese

Once the curds have been cooked and reached the desired firmness, the whey must be drained. Pour the curds and whey into a cheesecloth-lined colander or mold to separate the solid curds from the liquid whey. Allow whey to drain naturally, then fold the cheesecloth over the curds to prepare for pressing.

Pressing expels additional whey and helps the curds knit together to form a solid cheese mass. The amount of pressure and duration vary based on cheese type and moisture content goals.

Typical pressing guidelines:

  • Use weights or a mechanical press to apply consistent pressure.
  • Begin with light pressure to avoid excessive whey loss.
  • Increase pressure gradually over several hours.
  • Total pressing time can range from 2 hours to overnight.

Salting and Aging

After pressing, the cheese is salted either by rubbing dry salt onto its surface, mixing salt into the curds before pressing, or soaking the cheese in a brine solution. Salt enhances flavor, controls moisture, and acts as a preservative by inhibiting unwanted microbial growth.

Aging or affinage is the process where cheese matures under controlled temperature and humidity conditions. During this stage, complex biochemical changes develop the cheese’s flavor, aroma, and texture. Aging times vary widely, from a few days for fresh cheeses to several months or years for hard cheeses.

Factors influencing aging:

  • Temperature: Typically between 8°C and 15°C (46°F to 59°F).
  • Humidity: Maintained around 80-95% to prevent drying.
  • Airflow: Moderate airflow prevents mold overgrowth.
  • Turning: Regularly turning the cheese ensures even maturation.

Preparing and Testing Raw Milk for Cheese Making

Before beginning the cheese-making process, it is essential to ensure that the raw milk is suitable for consumption and cheese production. Raw milk can harbor bacteria, so proper handling and testing are critical to achieve safe and high-quality cheese.

Start by sourcing fresh raw milk from a trusted dairy farm with good animal health and sanitation practices. Milk should be collected in sterile containers and kept refrigerated at 4°C (39°F) or below until use.

Conduct the following tests and preparations:

  • Visual and Olfactory Inspection: Check for any off-colors, unusual odors, or visible contamination. Fresh raw milk should be white or creamy with a mild, pleasant smell.
  • Temperature Control: Maintain milk at a controlled temperature to prevent spoilage. Avoid temperature fluctuations above 7°C (45°F).
  • Microbial Testing: Perform simple tests such as the methylene blue reduction test to estimate bacterial load. If possible, send samples for laboratory microbial analysis.
  • Fat and Protein Content: Use a lactometer and cream test or professional milk analyzers to determine the milk’s composition, which influences cheese yield and texture.

If raw milk passes these initial checks, it can be used directly for cheese-making. However, some cheesemakers prefer light pasteurization to reduce undesirable microbes while preserving natural enzymes and flavors.
