Beginner’s Guide to Making Brine for Cheese
Why Brine is Needed
Brining is an essential step in the cheesemaking process, particularly for hard cheeses that require a short aging period. The primary reasons for using brine in cheesemaking include:
- Flavor Enhancement: Brining adds a salty flavor to the cheese.
- Preservation: The high salinity of the brine helps to inhibit the growth of undesirable bacteria and molds.
- Moisture Control: Brine helps to draw out whey from the cheese, reducing its moisture content.
- Rind Development: Brining aids in the formation of a rind on the cheese, which is crucial for aging.
What Brine Does to Cheese
When cheese is soaked in a brine solution, several important processes occur:
- Salt Absorption: The cheese absorbs salt from the brine, which helps to enhance its flavor and preserve it.
- Whey Expulsion: The salt in the brine draws moisture (whey) out of the cheese, which helps to firm up the cheese and develop a rind.
- Microbial Control: The high salt concentration in the brine inhibits the growth of unwanted bacteria and molds, ensuring the cheese remains safe to eat.
Brine Solution Ratio
Here is a beginner-friendly table for common brine solution ratios:
| Brine Concentration | Salt (grams) | Water (liters) |
|---|---|---|
| 10% | 100 | 1 |
| 12% | 120 | 1 |
| 18% | 180 | 1 |
| 20% | 200 | 1 |
| 24% | 240 | 1 |
| 26% (Saturated) | 260 | 1 |
This table shows how many grams of salt you need to add to 1 liter of water to make different brine concentrations.
For example, to make an 18% brine solution, you would add 180 grams of salt to 1 liter of water.
The 26% concentration is considered a saturated brine, meaning no more salt can dissolve in the water at that point.
Using this simple ratio of salt to water makes it easy to scale the brine solution up or down depending on how much you need. Just multiply the salt and water amounts by the desired number of liters.
Different brine concentrations are used for different types of cheeses and purposes in the cheesemaking process. Here’s a table that explains why you might use various brine concentrations:
| Brine Concentration | Purpose/Type of Cheese | Explanation |
|---|---|---|
| 10% | Fresh Cheeses (e.g., Feta) | A lower concentration is used for fresh cheeses to avoid over-salting and to maintain a softer texture. |
| 12% | Semi-Hard Cheeses (e.g., Gouda) | Slightly higher concentration helps in developing a firmer texture while still being gentle enough for semi-hard cheeses. |
| 18% | Hard Cheeses (e.g., Cheddar) | Higher concentration is used for hard cheeses to ensure proper rind formation and moisture control. |
| 20% | Hard Cheeses (e.g., Parmesan) | Used for very hard cheeses that require a strong rind and significant moisture reduction. |
| 24% | Specialty Cheeses (e.g., Swiss) | High concentration for cheeses that need a robust rind and intense flavor development. |
| 26% (Saturated) | Long-Aged Cheeses (e.g., Pecorino) | Saturated brine is used for cheeses that will age for a long time, ensuring maximum moisture removal and microbial control. |
Why Different Brine Concentrations are Needed
- Fresh Cheeses: Fresh cheeses like Feta require a lower salt concentration (10%) to avoid becoming too salty and to maintain their soft texture.
- Semi-Hard Cheeses: Cheeses like Gouda benefit from a slightly higher concentration (12%) to help develop a firmer texture without over-salting.
- Hard Cheeses: Hard cheeses such as Cheddar need a higher concentration (18%) to ensure proper rind formation and to draw out more moisture.
- Very Hard Cheeses: Cheeses like Parmesan require even higher concentrations (20%) to develop a strong rind and reduce moisture content significantly.
- Specialty Cheeses: Some cheeses, like Swiss, need a very high concentration (24%) for robust rind development and intense flavor.
- Long-Aged Cheeses: For cheeses that will age for a long time, such as Pecorino, a saturated brine (26%) is used to ensure maximum moisture removal and microbial control.
By using the appropriate brine concentration for each type of cheese, you can achieve the desired texture, flavor, and preservation characteristics.
Saturated Brine
A saturated brine solution is one where the salt concentration is so high that no more salt can dissolve in the water. This typically occurs at around 26% salt concentration. Saturated brine is important because:
- Consistent Salt Levels: It ensures a consistent salt level in the cheese.
- Quick Moisture Removal: It pulls moisture from the cheese surface quickly, aiding in rind formation.
- Microbial Control: It provides a hostile environment for unwanted bacteria and molds.
Why Calcium Chloride is Added to Brine
Calcium chloride is added to brine to maintain the calcium balance between the brine and the cheese. This is important because:
- Prevents Softening: Without calcium chloride, calcium can leach out of the cheese into the brine, causing the cheese to become soft and slimy.
- Maintains Texture: It helps to maintain the firm texture of the cheese by ensuring the proteins remain bonded.
Step by step guide on how to make brine for cheese
| Step | Description | Details |
|---|---|---|
| 1 | Gather Ingredients | – Non-iodized salt – Water – Calcium chloride (30% solution) – White vinegar (optional, for pH adjustment) |
| 2 | Prepare Water | – Boil the water to sterilize it. – Let the water cool to room temperature. |
| 3 | Measure Salt | – Refer to the brine concentration table to determine the amount of salt needed. – Example: For an 18% brine, measure 180 grams of salt per liter of water. |
| 4 | Dissolve Salt | – Add the measured salt to the cooled water. – Stir until the salt is completely dissolved. |
| 5 | Add Calcium Chloride | – Add 1.5-2 teaspoons of calcium chloride per liter of brine. – Stir well to ensure it is evenly distributed. |
| 6 | Adjust pH (if needed) | – Use pH testing strips to measure the pH of the brine. – The pH should be around 5.4-4.9. – Add small amounts of white vinegar to lower the pH if necessary. |
| 7 | Cool the Brine | – Chill the brine to the desired temperature, typically 10-12°C (50-54°F). |
| 8 | Brine the Cheese | – Submerge the cheese in the brine for the recommended time based on the type of cheese. |
| 9 | Reuse and Store Brine | – Strain the brine to remove particles. – Boil and cool the brine to sterilize it. – Add more salt if needed to maintain concentration. – Store in a sealed container in the refrigerator. |
Why pH is Important
The pH of the brine is important because it affects the texture and microbial stability of the cheese. A pH that is too high or too low can lead to undesirable changes in the cheese, such as sliminess or excessive hardness.
How to Adjust and Read pH
- Adjusting pH: Add small amounts of white vinegar to lower the pH or a mild base to raise it.
- Reading pH: Use pH testing strips to measure the pH of the brine. Dip the strip into the brine and compare the color change to the provided scale.

Cheese Brine Temperature
The temperature of the brine should be around 10-12°C (50-54°F). This temperature range ensures optimal salt absorption and moisture removal from the cheese.
Reusing Brine
Brine can be reused multiple times, but it needs to be maintained properly:
- Strain and Boil: Strain the brine to remove any particles and boil it to kill any unwanted bacteria.
- Add Salt: Add more salt to maintain the desired concentration.
- Store Properly: Store the brine in a sealed container in the refrigerator.
Storage of Brine
- Container: Use a non-reactive container, such as plastic or glass.
- Temperature: Store the brine at a cool temperature, ideally in the refrigerator.
- Maintenance: Regularly check the salt concentration and pH, and adjust as needed.
By following these steps and guidelines, you can create and maintain an effective brine solution for your cheesemaking projects, ensuring your cheese develops the desired flavor, texture, and microbial stability.
