Blue cheese, with its distinctive aroma and pungent flavor, is a culinary adventure in every bite. But did you know you can embark on this adventure yourself, right in your own kitchen? Making blue cheese at home is a rewarding process that allows you to control every aspect of the cheese, from the milk source to the intensity of the blue veins. This comprehensive guide will walk you through each step, offering insights and tips to help you create a truly remarkable blue cheese.
Understanding Blue Cheese: A Journey into Flavor and Mold
Blue cheese isn’t just any cheese; it’s a testament to the power of controlled mold growth. The characteristic blue veins are caused by Penicillium cultures, typically Penicillium roqueforti or Penicillium glaucum, which are introduced during the cheesemaking process. These molds thrive in the cheese’s interior, breaking down proteins and fats to create the unique flavors and textures we associate with blue cheese.
The Science Behind the Blue: What Makes it Special?
The magic of blue cheese lies in the way the Penicillium molds interact with the cheese. These molds require oxygen to grow, which is why blue cheeses are often pierced with needles or wires during aging. This creates tiny air channels throughout the cheese, allowing the mold to flourish and develop its distinctive blue-green veins. As the mold grows, it produces enzymes that break down the cheese’s fats and proteins. This process releases volatile compounds that contribute to the cheese’s pungent aroma and complex flavor profile, ranging from tangy and salty to earthy and sometimes even slightly sweet.
Different Types of Blue Cheese: Exploring the Spectrum of Flavor
The world of blue cheese is incredibly diverse, with each type offering a unique sensory experience. Roquefort, made from ewe’s milk and aged in the Roquefort caves of France, is perhaps the most famous. Gorgonzola, an Italian blue cheese made from cow’s milk, is known for its creamy texture and milder flavor compared to Roquefort. Stilton, a British blue cheese, boasts a rich, tangy flavor and a crumbly texture. Other notable blue cheeses include Bleu d’Auvergne, Danish Blue, and many artisanal varieties. The type of milk used, the specific Penicillium culture employed, and the aging conditions all contribute to the unique characteristics of each blue cheese.
Gathering Your Supplies: The Essential Toolkit for Cheesemaking
Before you begin your blue cheese-making adventure, you’ll need to assemble the necessary equipment and ingredients. Investing in quality supplies will significantly increase your chances of success and ensure a safe and enjoyable cheesemaking experience.
Essential Equipment: Setting Up Your Cheesemaking Station
A successful cheesemaking operation relies on having the right tools at your disposal. These are some of the must-have items:

- Measuring spoons and cups: Precise measurements are essential for adding cultures and rennet.
- A long, stainless steel knife: Used for cutting the curd evenly.
- A cheesecloth: Used for draining the whey and shaping the cheese. Choose a tightly woven cheesecloth to prevent the curd from escaping.
- A cheese mold: This provides the shape for your blue cheese. A mold with drainage holes is ideal.
- A sanitizing solution: Use a food-grade sanitizing solution to clean all your equipment thoroughly before and after use.
- Needles or wires: For piercing the cheese to allow oxygen to reach the Penicillium mold.
- A container for aging: A plastic container with a lid that allows some airflow is suitable for aging blue cheese.
- Optional items: A pH meter can be helpful for monitoring the acidity of the milk, but it’s not essential for beginners.
Key Ingredients: Sourcing the Best for Optimal Flavor
The quality of your ingredients will directly impact the flavor and texture of your blue cheese. Here’s what you’ll need:
- High-quality milk: Raw milk is often preferred for its rich flavor and natural enzymes, but pasteurized milk can also be used. If using pasteurized milk, opt for non-ultra-pasteurized milk. Cow’s milk is the most common choice, but goat’s or sheep’s milk can also be used to create unique blue cheese variations.
- Cheesemaking cultures: These cultures are essential for acidifying the milk and developing the desired flavor profile. A mesophilic starter culture is typically used.
- Penicillium Roqueforti or Penicillium Glaucum: This is the magic ingredient that creates the blue veins. It’s available from cheesemaking supply stores.
- Rennet: Rennet is an enzyme that coagulates the milk, forming the curd. Vegetable rennet, animal rennet, or microbial rennet can be used. Follow the manufacturer’s instructions for dosage.
- Calcium chloride (optional): This can be added to pasteurized milk to improve curd formation.
- Salt: Use non-iodized salt to season the cheese and control moisture levels.
The Cheesemaking Process: A Step-by-Step Guide
Now that you’ve gathered your supplies and ingredients, it’s time to dive into the cheesemaking process. This detailed guide will walk you through each step, providing clear instructions and helpful tips to ensure a successful outcome.
Step 1: Preparing the Milk
Begin by sanitizing all your equipment thoroughly. Pour the milk into the stainless steel pot and gently heat it to 86-90°F (30-32°C), stirring occasionally to ensure even heating. Maintaining the correct temperature is crucial for optimal culture activity.
Step 2: Adding Cultures and Penicillium
Once the milk reaches the desired temperature, remove it from the heat. Add the mesophilic starter culture and the Penicillium Roqueforti or Penicillium Glaucum, following the instructions on the culture packets. Gently stir the cultures into the milk for a few minutes to ensure even distribution. It’s crucial to evenly distribute the Penicillium for consistent veining.
Step 3: Coagulation with Rennet
Dilute the rennet in a small amount of cool, non-chlorinated water. Gently stir the diluted rennet into the milk for about one minute. Cover the pot and let it sit undisturbed for 60-90 minutes, or until a firm curd forms. You can test the curd by inserting a clean finger into the milk at an angle and lifting it gently. If the curd breaks cleanly, it’s ready to be cut.
Step 4: Cutting the Curd
Using a long, stainless steel knife, cut the curd into 1/2-inch cubes. The smaller the cubes, the drier the final cheese will be. Cut slowly and carefully to avoid shattering the curd.
Step 5: Stirring and Heating the Curd
After cutting the curd, gently stir it for 15-20 minutes, maintaining the temperature at 86-90°F (30-32°C). This helps to expel whey from the curd and firm it up.
Step 6: Draining the Whey
Line a colander with cheesecloth and carefully pour the curd and whey mixture into the cheesecloth. Let the whey drain for several hours, or until the curd has formed a solid mass. You can gently press the curd with a weight to speed up the draining process.
Step 7: Salting the Curd
Once the curd has drained sufficiently, remove it from the cheesecloth and crumble it into a bowl. Add salt to the crumbled curd, using about 2-3% salt by weight of the curd. Mix the salt in thoroughly. Salting is crucial for flavor development, moisture control, and inhibiting unwanted bacteria growth.
Step 8: Molding the Cheese
Pack the salted curd into a cheese mold lined with cheesecloth. Gently press the curd to remove any remaining air pockets. Place the mold in a cool, humid place (around 50-55°F or 10-13°C) for several days, turning it regularly to ensure even drainage.
Step 9: Piercing the Cheese
After a few days, when the cheese has formed a firm shape, it’s time to pierce it to allow oxygen to reach the Penicillium mold. Use sterilized needles or wires to create several holes throughout the cheese, spacing them about an inch apart. This step is essential for the development of the blue veins.
Step 10: Aging the Cheese
Place the pierced cheese in a container suitable for aging, such as a plastic container with a lid that allows some airflow. Maintain a temperature of 50-55°F (10-13°C) and a humidity level of 85-95%. Age the cheese for 2-4 months, or longer, depending on your desired flavor intensity. Turn the cheese regularly during aging to ensure even mold growth.
Troubleshooting: Addressing Common Cheesemaking Challenges
Even with careful attention to detail, cheesemaking can sometimes present challenges. Here are some common issues and how to address them:
- Weak curd formation: This can be caused by using milk that is too old, insufficient rennet, or incorrect milk temperature. Try using fresher milk, increasing the amount of rennet slightly, or ensuring the milk temperature is within the recommended range. Calcium chloride can also help improve curd formation in pasteurized milk.
- Insufficient blue veining: This can be due to inadequate piercing, low humidity, or insufficient Penicillium culture. Make sure to pierce the cheese thoroughly, maintain a high humidity level during aging, and use a fresh, viable Penicillium culture.
- Off-flavors: Off-flavors can be caused by contamination, incorrect aging conditions, or using poor-quality ingredients. Ensure all equipment is thoroughly sanitized, maintain proper temperature and humidity levels during aging, and use high-quality milk and cultures.
- Excessive mold growth on the surface: This can be controlled by wiping the cheese with a brine solution (saltwater) or a vinegar solution.

What specific type of milk is best for making blue cheese?
The best type of milk to use for making blue cheese is whole milk from cows, sheep, or goats. Each milk type will impart a slightly different flavor profile to your final cheese. Cow’s milk is the most common and readily available, resulting in a milder, creamier blue cheese. Sheep’s milk produces a richer, nuttier flavor, while goat’s milk yields a tangier and more assertive cheese.
Regardless of the animal source, the milk should be fresh, unpasteurized if possible (though pasteurized milk can be used), and of high quality. Avoid using ultra-pasteurized milk, as the intense heat treatment can damage the milk proteins necessary for proper curd formation. Fresh, high-fat milk will lead to a smoother, more flavorful blue cheese.
What is Penicillium Roqueforti and why is it essential for blue cheese?
Penicillium Roqueforti is a specific mold culture that is absolutely essential for creating blue cheese. It’s what gives blue cheese its distinctive blue or green veins and characteristic tangy, pungent flavor. Without Penicillium Roqueforti, you simply wouldn’t have blue cheese; you’d have a different type of cheese altogether.
This mold works by breaking down the fats and proteins in the cheese during the aging process. This breakdown, facilitated by enzymes released by the mold, produces the unique aromas and flavors associated with blue cheese. It also contributes to the cheese’s softer texture as the structure is weakened.
How do I ensure proper mold growth inside the cheese?
To encourage proper mold growth inside your blue cheese, you need to create the right environment for Penicillium Roqueforti to thrive. This involves several crucial steps. Firstly, the cheese curds need to be loosely packed, creating air pockets throughout the cheese. These air pockets are essential for the mold to access oxygen, which it needs to grow.
Secondly, piercing the cheese with sterile needles after forming allows oxygen to penetrate deeper into the interior. Make these piercings strategically, spacing them evenly across the surface of the cheese. Finally, maintaining a humid and cool aging environment (typically around 90-95% humidity and 50-55°F) is crucial. These conditions prevent the cheese from drying out and encourage mold growth.
What are the risks of making blue cheese at home, and how can I mitigate them?
One of the primary risks of making blue cheese at home is contamination with unwanted molds or bacteria. This can lead to off-flavors, spoilage, or, in rare cases, the production of harmful toxins. Therefore, sanitation is paramount. Ensure all equipment, including pots, spoons, molds, and needles, is thoroughly sterilized before use.
To mitigate these risks, use a reputable source for your Penicillium Roqueforti culture and follow the recipe meticulously. Maintain a clean working environment and monitor the cheese carefully during aging for any signs of unwanted mold growth (e.g., colors other than blue or green). If you suspect contamination, discard the cheese immediately.
How long does it take to make blue cheese from start to finish?
The entire process of making blue cheese, from preparing the milk to enjoying the final product, typically takes several weeks to a few months. The active cheesemaking phase, including curd formation and shaping, takes only a day or two. However, the crucial aging process is what dictates the total time.
Aging allows the Penicillium Roqueforti mold to develop and impart its characteristic flavors and textures. This process can take anywhere from 6 weeks to 3 months or even longer, depending on the desired intensity of flavor. Regularly monitoring the cheese during aging is important to ensure proper development and prevent spoilage.
What are some signs that my blue cheese has gone bad?
Several signs can indicate that your homemade blue cheese has gone bad and should be discarded. Obvious indicators include the presence of unwanted molds, such as pink, orange, or black molds, on the surface or inside the cheese. These molds can be harmful and indicate spoilage.
Other warning signs include a strong ammonia smell, a slimy or excessively sticky texture, or a dramatically altered flavor profile that is unusually bitter or off-putting. If you observe any of these signs, it’s best to err on the side of caution and discard the cheese to avoid potential health risks.
Can I use different types of rennet when making blue cheese?
Yes, different types of rennet can be used when making blue cheese, but the choice can subtly influence the final product. Traditionally, animal rennet, derived from the stomach lining of young ruminant animals, was the standard. Animal rennet generally produces a firmer curd and a more complex flavor profile.
Vegetarian rennet, derived from plant sources or microbial fermentation, is a suitable alternative for those who prefer not to use animal products. These rennets often create a slightly softer curd and may result in a milder flavor. Ultimately, the best type of rennet to use depends on your personal preferences and dietary restrictions.
