The ultimate method: How to keep your cheese fresh for weeks
What should be considered when storing and preserving cheese?
Cheese is far more than just a foodstuff – it's a cultural asset, a delicacy, and a genuine natural product. But precisely because it's a living, aging process, proper storage is crucial for flavor, shelf life, and hygiene. To store cheese optimally, you need to understand the specific characteristics of each variety and choose the appropriate packaging materials. This article will tell you everything you need to know about proper cheese storage, the advantages and disadvantages of different packaging materials, and provide practical tips for every type of cheese – including a sustainable and innovative alternative: a cheese wrap made from bioplastic based on starch.
Why store cheese properly?
Cheese is a delicate product. If stored incorrectly, it quickly loses its aroma, dries out, or begins to mold. Storage affects:
- Maturation: Cheese continues to ripen even in the refrigerator. Temperatures that are too high accelerate this process, while temperatures that are too low stop it.
- Humidity: Too much moisture promotes mold growth, too little causes it to dry out.
- Aroma protection: Cheese easily absorbs foreign odors – especially when stored in the open.
- Shelf life: The storage period varies greatly depending on the variety.
The rule of thumb is: the lower the water content, the longer the cheese will keep.
General tips for storing cheese
- Temperature: The ideal temperature is 5–8 °C. The vegetable drawer in the refrigerator usually offers the best conditions.
- Humidity: The optimal humidity is 70–85%. Air that is too dry makes cheese brittle.
- Packaging: Cheese should generally not be packaged airtight. It needs to "breathe." But there are exceptions.
- Separation of varieties: Different types of cheese should be stored separately to avoid mixing of aromas and transfer of mold.
- Hygiene: Always cut cheese with a clean knife. Breadcrumbs or other residue promote mold growth.
Types of cheese and their storage
Hard cheeses like Parmesan, Emmental, or mountain cheese are particularly robust and have a long shelf life. Due to their low water content, they can last for several weeks in the refrigerator without losing quality. Hard cheese is best stored in breathable cheese paper or a beeswax wrap. Alternatively, a starch-based bioplastic bag is also very suitable, as it regulates moisture and protects the aroma. Hard cheese can even be frozen – ideal for use in grated form.
Semi-hard cheeses like Gouda, Tilsiter, or Edam require slightly more careful storage. They should be wrapped in a breathable material and kept in the refrigerator's vegetable drawer. It's important to prevent condensation, as this promotes mold growth. Semi-hard cheeses should be checked regularly and rewrapped as needed. Cheese paper, beeswax wraps, or special natural cheese bags (cornstarch bags) are recommended.
Soft cheeses like Brie, Camembert, or Gorgonzola are particularly delicate. They continue to ripen even in the refrigerator and can quickly become overripe. Storage should be in the lower part of the refrigerator, at around 4–6 °C (39–43 °F). Soft cheeses should not be stored in airtight containers, but should still be protected from strong odors – for example, in a slightly open box, in the original packaging, or in a breathable cornstarch bag/film. An ammonia-like odor is a sign of overripeness.
Fresh cheeses like mozzarella, ricotta, or cottage cheese should be stored in a tightly sealed container, preferably near the top of the refrigerator where it's coldest. Because fresh cheese is highly perishable, it should be consumed within a few days of opening. Important: Always use clean utensils to remove the cheese and prevent bacterial growth.
Packaging materials compared
| Material | Benefits | Disadvantages |
| Plastic film (petroleum-based) | Affordable, flexible, good barrier effect | Airtight, promotes mold, microplastic risk |
| Glass container | Reusable, odorless | Heavy, not breathable |
| aluminum foil | Good barrier, malleable | Reacts with salt, environmental problem |
| cheese paper | Breathable, protects against dehydration | Not always petroleum-based plastic-free |
| beeswax cloth | Natural, reusable, breathable | Not suitable for all varieties |
| Starch film/bag | Compostable, microplastic-free, breathable, pollutant-free | heat sensitive |
Sustainable cheese storage in cheese foil based on starch
The special NaKu cheese sleeping bag is an innovative cheese bag made from bioplastic, produced using non-GMO cornstarch. It is:
- breathable and moisture-regulating
- Compostable according to DIN EN 13432
- free from microplastics and pollutants
- ideal for semi-hard and hard cheeses
Thanks to its special structure, the cheese sleeping bag protects the cheese from drying out and odor transfer without sealing it airtight. This makes it a sustainable alternative to plastic and aluminum foil, especially for environmentally conscious households. It is available in rolls of 10 for home use and in packs of 100 for cheese counters.
FAQ – Frequently asked questions about the optimal storage and preservation of cheese
What is the best way to store cheese in the refrigerator?
Cheese should be stored in the vegetable drawer at 5–8 °C. Breathable packaging such as cheese paper or bioplastic bags is ideal, as it prevents drying out and preserves the aroma.
Why shouldn't cheese be packaged airtight?
Cheese is a living product that continues to mature. Airtight packaging promotes moisture buildup and mold growth. Breathable materials regulate the climate better.
Which packaging is most sustainable for cheese?
Bioplastics based on starch, such as those used in the NaKu cheese sleeping bag, are compostable and microplastic-free. They offer an environmentally friendly alternative to petroleum-based plastics and aluminum foil.
Can I freeze cheese?
Yes, hard cheeses like Parmesan or mountain cheese freeze well – ideal for later use as grated cheese. Soft and fresh cheeses are less suitable.
How can I tell if cheese has gone bad?
Signs include an unpleasant odor (e.g., ammonia), a slimy surface, or visible mold outside the bark. If unsure, it's best to dispose of it.
What is the advantage of the NaKu cheese sleeping bag compared to conventional cheese paper?
The cheese sleeping bag is breathable, moisture-regulating, and compostable. It protects the cheese without petroleum-based plastic.
Which types of cheese are particularly sensitive during storage?
Soft cheeses like Brie or Camembert are sensitive to temperature and humidity. They should be stored separately and not in airtight containers.
How long does cheese keep after opening?
It depends on the type of cheese: hard cheese several weeks, semi-hard cheese about 1–2 weeks, soft cheese a few days, fresh cheese 2–5 days. Always pay attention to the smell and consistency.
Can I store different types of cheese together?
It's best not to. Different varieties affect each other's aroma and can transmit mold. Separating them is more hygienic and makes better use of the flavor.
