How to make raw whey? A simple guide to homemade liquid protein

Did you know that raw milk, when left to ferment, naturally separates into two nutrient-dense components: curds and whey? Learning how to make raw whey at home is a traditional process that allows you to create a pure, additive-free liquid rich in protein and beneficial compounds.

Quick Summary

This guide provides step-by-step instructions for producing raw whey from either raw milk or yogurt. It covers the necessary equipment, the simple fermentation process, and tips for proper straining and storage, helping you create your own natural protein source.

Key Points

• Natural Separation: Raw milk naturally ferments and separates into curds and liquid whey at room temperature, a process known as clabbering.

• Easy Alternatives: You can also produce whey quickly and simply by straining plain yogurt or kefir overnight in the refrigerator.

• Preserves Nutrients: The minimal heat and processing involved in making raw whey preserve beneficial enzymes, fats, and immunoglobulins, unlike high-heat commercial methods.

• Versatile Use: Homemade whey is a tangy liquid that can be used in smoothies, fermented drinks, baked goods, and as a starter culture for vegetables.

• Control Ingredients: Making your own raw whey ensures a product free from the additives, fillers, and artificial sweeteners common in commercial supplements.

• Different Digestion: Unlike rapid-digesting whey isolates, raw whey contains lactose and other components that lead to a slower, more sustained release of nutrients.

• Utilize Byproducts: The leftover curds from the process can be used to make fresh cheese, spreads, or dips.

Introduction to Homemade Raw Whey

Creating your own raw whey at home is a process that reconnects you with traditional food preservation methods. Unlike the heavily processed commercial whey powders, homemade raw whey is a liquid byproduct of fermentation that retains more of its natural enzymes, probiotics, and immunoglobulins. The final product is a tangy, nutrient-dense liquid that can be used in a variety of recipes, from smoothies to fermenting vegetables. The primary difference between a store-bought supplement and homemade raw whey lies in the processing; commercial powders undergo high heat and filtration, which strips away some beneficial components, while the home method is a low-temperature, minimal-intervention approach.

Method 1: Using Raw Milk for Natural Clabbering

This is the most traditional method, relying on the natural bacteria present in unpasteurized milk to do the work of separating the curds and whey. This process, known as clabbering, is a clear sign that the milk is alive and rich in beneficial microorganisms.

Ingredients and Equipment

• Raw, unpasteurized milk
• Large, clean glass jar
• A breathable cover (like a cheesecloth or towel)
• Large bowl
• Unbleached cheesecloth
• Strainer

Step-by-Step Instructions

1. Pour the Milk: Pour the desired amount of raw milk into your clean glass jar. Do not fill it completely, leaving some room for expansion.
2. Cover: Cover the jar loosely with a cheesecloth or a clean tea towel. This allows air to circulate while keeping out dust and insects.
3. Ferment: Leave the jar at room temperature, away from direct sunlight. The fermentation time can vary from 4 to 7 days, depending on the ambient temperature. In warmer conditions, the process will be faster.
4. Observe Separation: Watch for the milk to thicken and separate. You will see solid white curds forming and a yellowish liquid, the whey, collecting around them. The milk will develop a tangy, slightly sour smell.
5. Strain: Once a clear separation has occurred, place your strainer over a large bowl and line it with the cheesecloth. Gently pour the clabbered milk mixture into the cheesecloth.
6. Collect the Whey: Allow the whey to drip into the bowl. This can take several hours. For a clearer whey, you can let it strain longer. Refrigerate the collected whey in a sealed jar.

Method 2: Using Yogurt or Kefir for Quick Whey

If you don't have access to raw milk or want a faster process, you can get high-quality whey by straining plain, unsweetened yogurt or kefir. This method yields whey with a slightly different flavor profile and consistency.

Ingredients and Equipment

• Plain, full-fat yogurt or kefir (store-bought or homemade)
• Cheesecloth
• Strainer
• Bowl

Step-by-Step Instructions

1. Prepare Strainer: Set up your strainer over a bowl and line it with a piece of unbleached cheesecloth.
2. Add Yogurt: Spoon the yogurt or kefir into the lined strainer.
3. Strain: Cover the setup with a lid or towel and place it in the refrigerator. Allow the whey to drip out over 12 to 24 hours. The longer it drains, the thicker the remaining yogurt cheese will be, and the more whey you'll collect.
4. Store the Whey: Pour the liquid whey into a clean jar and store it in the fridge for future use.

Raw vs. Commercial Whey: A Comparison

To highlight the key differences, here is a comparison of homemade raw whey versus typical commercial whey protein powders.

Feature	Homemade Raw Whey (Liquid)	Commercial Whey (Powder)
Processing	Minimal; relies on natural fermentation	High; uses heat, acid, and filtration
Nutrient Profile	Contains natural fats, lactose, enzymes, probiotics, immunoglobulins	Concentrated protein, often isolated; other nutrients removed
Additives	None; pure and natural	Often includes flavorings, artificial sweeteners, preservatives, and thickeners
Form	Tangy, yellowish liquid	Sweet, flavored powder
Digestion	Slower, sustained release of nutrients	Fast absorption; often taken post-workout
Control	Full control over ingredients; you know exactly what's in it	Rely on manufacturer information; composition can vary

How to Use Your Homemade Raw Whey

Your freshly made raw whey is a versatile ingredient that can be incorporated into many aspects of your diet. Its tangy flavor and high nutritional content make it a perfect addition to various recipes.

List of Uses

• Smoothies: Add a splash of whey to your morning smoothie to boost the protein content and add a tangy twist.
• Fermented Drinks: Use it as a starter for making naturally fermented soda, kvass, or other probiotic beverages.
• Soups and Sauces: Add it to soups, stews, or gravies for extra flavor and nutrients. Its acidic nature can tenderize meat.
• Baking: Use whey in place of water or milk in baking recipes for bread, pancakes, or muffins to enhance the protein profile.
• Soaking Grains and Legumes: A small amount of whey can aid in the digestion and nutrient absorption of grains and legumes by activating enzymes during the soaking process.
• Cultured Vegetables: It acts as a great starter culture for fermenting vegetables like pickles or sauerkraut, speeding up the process and ensuring a probiotic-rich result.

Conclusion: The Benefits of Homemade

Making your own raw whey is a rewarding process that provides you with a clean, natural, and nutrient-dense protein source. By opting for the simple method of fermenting raw milk or straining yogurt, you bypass the industrial processing that can degrade the quality of commercial protein powders.

Considerations for Success

To achieve the best results, start with high-quality ingredients. For the raw milk method, ensure your milk comes from a reputable source. For the yogurt method, use plain, full-fat yogurt without added gelatin or pectin. Always use clean equipment and store your finished whey in the refrigerator to maintain freshness. Remember that homemade raw whey is a living food and its flavor will be tart and natural, unlike the sweetened taste of many commercial products. Embrace the process and enjoy the pure, natural nutrition that comes from creating your own whey.

What to Expect

• Flavor: Expect a tangy, slightly sour taste. This is completely normal and indicates a successful fermentation.
• Appearance: Raw milk whey is a yellowish, slightly translucent liquid. The clarity can depend on the fat content of the milk and how long it was strained.
• Consistency: The consistency will be thin, similar to water, but with a slight viscosity depending on the draining time.

Troubleshooting Tips

• No Separation: If your raw milk doesn't separate, it might not be truly raw or could be due to a low ambient temperature. Be patient and ensure the temperature is warm enough.
• Foul Smell: A pleasant, sour smell is expected, but a truly foul or putrid odor indicates spoilage. Discard the batch and try again with fresher milk.
• Cloudy Whey: If your whey is too cloudy, it may contain too much residual fat. Strain it for a longer period in the refrigerator to get a clearer liquid.
