Making raw cheese from raw milk is a time-honored tradition that connects us to the roots of artisanal food craftsmanship. In an era dominated by mass-produced dairy products, creating cheese from raw milk offers a unique opportunity to explore rich flavors, natural textures, and the authentic character that only minimally processed ingredients can provide. Whether you are a curious food enthusiast or an aspiring cheesemaker, understanding the basics of raw cheese production opens the door to a rewarding culinary adventure.
Raw milk, straight from the farm, carries a complex array of natural bacteria and enzymes that contribute to the distinctive taste and texture of raw cheese. Unlike pasteurized milk, which undergoes heat treatment to eliminate microbes, raw milk preserves these elements, allowing for a more vibrant and nuanced cheese profile. However, working with raw milk also requires careful attention to hygiene and technique to ensure safety and quality, making the cheesemaking process both an art and a science.
Embarking on the journey of making raw cheese involves appreciating the delicate balance between tradition and precision. From selecting the freshest raw milk to nurturing the curds as they transform into cheese, each step plays a crucial role in shaping the final product. This sets the stage for a deeper exploration of the methods, considerations, and joys of crafting raw cheese from raw milk
Preparing Raw Milk for Cheesemaking
Before beginning the cheesemaking process, it is essential to prepare the raw milk properly to ensure optimal curd formation and flavor development. First, the raw milk should be strained through a fine mesh or cheesecloth to remove any debris or impurities. This step does not affect the natural microflora critical for raw cheese but enhances cleanliness.
Next, allow the milk to reach the appropriate temperature for the culture and rennet addition. Typically, raw milk is heated gently to between 30°C and 37°C (86°F to 98.6°F), depending on the type of cheese being made. Avoid overheating, as excessive heat can kill beneficial bacteria and enzymes naturally present in the raw milk.
If you choose to add starter cultures, select strains compatible with raw milk to encourage proper acidification and flavor development. Although raw milk contains native bacteria, starter cultures help control the fermentation process and improve consistency.
Key points to consider during preparation:
Use fresh, high-quality raw milk from healthy animals.
Strain milk carefully to maintain microbial integrity.
Monitor temperature precisely with a dairy thermometer.
Select starter cultures based on cheese type and milk characteristics.
Coagulating Raw Milk
Coagulation is the critical step in transforming liquid raw milk into curds. This process typically involves adding rennet, an enzyme complex that acts on the milk protein casein, causing it to clot. The choice of rennet (animal, vegetable, or microbial) depends on the desired cheese style and dietary preferences.
Add rennet diluted in cool, non-chlorinated water to the milk once it reaches the ideal temperature. Stir gently to distribute the enzyme evenly, then allow the milk to rest undisturbed. The coagulation time varies but generally takes 30 to 60 minutes. The resulting gel-like curd should have a clean break when tested with a knife or finger.
Factors influencing coagulation include:

Cutting and Cooking the Curd
Once the curd has set firmly, it must be cut to release whey and begin shaping the cheese texture. Use a clean knife or curd cutter to slice the curd into uniform cubes, typically ranging from 0.5 cm to 2 cm depending on the cheese style. Smaller curd pieces yield firmer cheese by expelling more whey.
After cutting, gently stir the curds to prevent clumping and promote even whey expulsion. Some cheese recipes call for cooking the curds by gradually raising the temperature, usually up to 38°C to 45°C (100°F to 113°F). This step encourages further whey separation and curd contraction, influencing moisture content and final texture.
Important considerations during cutting and cooking:
Cut curds evenly for consistent moisture and texture.
Stir gently to avoid breaking curds excessively.
Control heating rate and final temperature precisely.
Monitor curd texture frequently to avoid overcooking.
Draining and Pressing the Curds
After sufficient whey has been expelled, the curds are transferred to molds lined with cheesecloth for draining. Gravity draining allows residual whey to escape naturally, enhancing firmness and flavor concentration. The length of draining varies with the cheese type.
Pressing is often necessary to compact the curds and eliminate trapped whey. The pressure applied and duration depend on the desired moisture content and cheese style. Pressing can be done using a cheese press or by applying weights. Proper pressing develops the cheese’s structure and influences texture, from soft to hard cheeses.
Guidelines for draining and pressing:
Use clean cheesecloth and molds to maintain hygiene.
Adjust pressing pressure according to cheese moisture goals.
Turn the cheese regularly during pressing for uniform shape.
Avoid excessive pressure that may cause a dense or dry texture.

Preparing Raw Milk for Cheesemaking
Before beginning the cheesemaking process, it is essential to ensure the raw milk is of high quality and properly prepared. Raw milk straight from the source contains natural enzymes and beneficial bacteria critical for authentic raw cheese production, but it must be handled with care.
Source high-quality raw milk: Obtain milk from healthy animals that have not been treated with antibiotics or hormones. Confirm that the milk is fresh, clean, and free from contaminants.
Filter the milk: Use a fine mesh strainer or cheesecloth to remove any debris such as hair or dirt particles.
Bring milk to the proper temperature: Gently warm the raw milk to 85°F–90°F (29°C–32°C), which is an optimal range for adding starter cultures and rennet. Use a double boiler or a water bath for gradual heating to preserve beneficial microbes.
Measure milk volume: Knowing the exact volume of milk helps calculate the proper quantities of starter culture and rennet needed for consistent results.

Adding Starter Culture and Coagulating the Milk
The addition of starter culture and rennet initiates milk fermentation and coagulation, transforming liquid milk into curd, the fundamental step in cheesemaking.
Starter Culture: Introduce a mesophilic or thermophilic starter culture depending on the cheese style desired. Mesophilic cultures thrive at moderate temperatures (around 86°F/30°C) and are commonly used for cheeses like cheddar and gouda. Thermophilic cultures perform well at higher temperatures (104°F/40°C) and are typical for cheeses such as mozzarella and parmesan.
Inoculation: Sprinkle the starter culture evenly over the milk surface and allow it to rehydrate for 2–3 minutes. Then gently stir it into the milk to distribute the bacteria uniformly.
Ripening the Milk: Let the inoculated milk rest for 30–60 minutes at the target temperature to allow acidification. The bacteria begin converting lactose into lactic acid, lowering the pH and preparing the milk for coagulation.
Adding Rennet: Dilute the rennet in cool, non-chlorinated water (typically 1:10 ratio) to ensure even distribution. Stir the diluted rennet into the milk gently but thoroughly for about 30 seconds.
Coagulation Time: Allow the milk to set undisturbed for 30–60 minutes until a firm curd forms. The coagulation time varies depending on milk freshness, temperature, and rennet strength.

Cutting and Cooking the Curd
Once the milk has set into a firm curd, the next phase is cutting and cooking the curd to release whey and develop the desired cheese texture.
Cutting the Curd: Using a long knife or curd cutter, slice the curd vertically and horizontally into small cubes approximately 1/2 to 3/4 inch in size. Cutting increases the surface area for whey expulsion.
Resting: Allow the curds to rest for 5–10 minutes after cutting to firm up slightly and start whey separation.
Cooking the Curd: Slowly heat the curds to a target temperature depending on the cheese style. For example, cheddar curds are cooked to about 102°F (39°C), while mozzarella curds may only be heated to 105°F (40.5°C).
Stirring: Gently stir the curds during cooking to prevent matting and ensure even heat distribution. This also helps expel whey effectively.
Cooking Time: Gradually raise the temperature over 30–60 minutes, holding it steady once reached to achieve the proper curd texture.
