Glass cheese preservers are containers designed to keep cheese fresh for longer. They were manufactured in three sizes: two for home use (1.5 lb and 3 lb) and one for commercial use (30 lb). The home-sized models came in round and square shapes. The glass cheese preserver is believed to have been first manufactured by the U.S. Glass Company from 1928 until 1939, after which The Cambridge Glass Co. of Cambridge, Ohio, took over production from 1940 to 1953. To use a glass cheese preserver, a mixture of vinegar, salt, and water is placed at the bottom of the container, with the cheese held above the liquid on raised portions. The container is then kept in a cool place, such as a refrigerator or basement.

What You'll Learn
Use a mild solution of vinegar
Using a glass cheese preserver with a mild solution of vinegar is a great way to extend the shelf life of your cheese. This method is believed to inhibit mould growth, keeping your cheese fresh for longer.
To use this method, start by preparing a mild vinegar solution. White vinegar is preferred, and you should aim for a solution that comes about a third of the way up the glass bottom rests. The recommended amount is one-third pint of vinegar with one tablespoon of salt, diluted with water. This solution is then placed in the glass cheese preserver.
Next, place your cheese in the preserver, ensuring that it is raised above the vinegar solution. The preserver is designed with portions raised at the bottom to keep the cheese out of the solution. The vinegar solution creates an environment that discourages mould growth, helping to preserve your cheese.
It is important to note that this preservation method works best with hard or semi-hard cheeses, such as cheddar, gouda, parmesan, and Monterey Jack. These cheeses have a low moisture content, which makes them ideal for this preservation method. Softer cheeses may become mushy due to the introduction of additional moisture.
Additionally, it is recommended to keep your glass cheese preserver in a cool place, such as a pantry, kitchen, basement, or refrigerator. This further helps to extend the shelf life of your cheese.

Keep the preserver in a cool place
Glass cheese preservers are thick glass chambers with portions raised at the bottom to hold cheese above a mixture of vinegar, salt, and water, which is believed to help preserve the cheese. They were manufactured in three sizes: two home-sized models (1.5 lb and 3 lb) and one commercial-sized model (30 lb). The home-sized models came in round and square shapes.
To keep the preserver in a cool place, it is recommended to store it in a refrigerator, basement, pantry, or kitchen. The preserver should be kept in a cool, dark, and humid place, such as the produce storage container of a refrigerator. However, it is important to note that when stored in the refrigerator, the lid of the preserver may collect moisture and drip onto the cheese, affecting its flavour. To prevent this, ensure that the lid is removed daily to allow the cheese to receive fresh air.
Additionally, it is recommended to use mild or white vinegar in the preserver, as higher acidity levels may contribute to mould formation. Mild or fresh cheese should also be avoided due to its higher moisture content, which makes it more susceptible to mould growth. Instead, aged or harder cheeses are more suitable for storage in glass cheese preservers.
Overall, maintaining a cool temperature for the glass cheese preserver is crucial to prevent mould and maintain the quality of the cheese.

Prevent mould by using fresh cheese
A glass cheese preserver is a thick glass chamber with portions raised at the bottom to hold cheese above a mixture of vinegar, salt, and water, which is believed to help preserve the cheese.
To prevent mould by using fresh cheese, follow these steps:
Firstly, it is important to note that mild new cheese (not aged) has a higher moisture content and therefore moulds more quickly. Processed cheese is also not suitable for preservation due to the additional ingredients. To prevent mould, control the moisture around the cheese—it should not be too dry or too wet. When storing cheese, ensure that it is wrapped tightly to prevent exposure to air, as oxygen accelerates mould growth. You can use a vacuum sealer, plastic wrap, or cheese storage paper, with an additional layer of aluminium foil for extra protection. Minimise contact with your hands, as trace amounts of bacteria can be transferred to the cheese, encouraging mould growth. Instead, use food preparation gloves or a piece of plastic wrap as a barrier when handling the cheese.
Additionally, consider investing in a reusable cheese storage bag or wrapping it in parchment paper designed for cheese preservation. For soft cheeses like mozzarella, ricotta, and chèvre, keep them sealed in their original containers. However, for larger pieces of mozzarella, removing it from the brining solution and wrapping it in plastic can extend its freshness by up to 7 days in the refrigerator.
To further prevent mould, change the packing solution on fresh cheeses if it becomes contaminated. Use clean utensils to avoid contamination, and only change the solution if it looks or smells funny. If contamination occurs, replace it with a saltwater brine made by dissolving 1 tablespoon of salt in a few cups of water.

Avoid processed cheese
Glass cheese preservers are thick glass chambers with portions raised at the bottom to hold cheese above a mixture of vinegar, salt, and water. This mixture is believed to help preserve the cheese. The original cheese preservers were made by the U.S. Glass Company from 1928 until around 1939. From 1940 to 1953, they were made by The Cambridge Glass Co. of Cambridge, Ohio.
Processed cheese is not suitable for use in glass cheese preservers because of the ingredients added to milk during its production. In addition, mild, fresh cheeses have a higher moisture content and are more likely to become mouldy.
To avoid processed cheese, it is recommended to buy blocks of cheese and shred them yourself. This ensures that you know exactly what you are getting. It is best to avoid processed cheese slices, which are often packaged and individually wrapped. These slices may be convenient, but they often contain anti-caking agents and other additives. Instead, opt for real cheese, such as cheddar, havarti, or gouda. If you can afford it, organic cheese is always a better option.
Some other types of cheese to avoid include low-fat or non-fat cheeses, which are highly processed. Additionally, spray cheese is another heavily processed cheese product that is best avoided. This type of cheese is delivered from a pressurized can and contains unhealthy ingredients such as canola oil, sodium phosphate, and excessive amounts of salt.

Remove the lid daily
The glass cheese preserver is a thick glass chamber with portions raised at the bottom to hold cheese. The cheese is kept separate from a mixture of vinegar, salt, and water, which helps to preserve it. The lid is also made of glass and has a rim that sits loosely on the cheese chamber.
The lid of the glass cheese preserver must be removed daily. This is because the cheese needs to be exposed to fresh air. If the preserver is stored in the refrigerator, the lid may collect moisture, which can then drip onto the cheese and affect its flavour. Therefore, it is important to remove the lid every day, even if the preserver is kept in a cool place.
The glass cheese preserver was on the market for around 25 years, from the late 1920s to the early 1950s. During this time, it was manufactured in three sizes: two home-sized models (1.5 lb and 3 lb) and one commercial-sized model (30 lb). The home-sized models were available in round and square shapes.
To use the glass cheese preserver effectively, it is recommended to use mild vinegar, preferably white vinegar, and to fill the glass bottom rests with the vinegar solution to about one-third of the way up. The preserver should be kept in a cool place, such as a refrigerator, basement, or pantry.
