Yes, you can use a vacuum sealer to age cheese at home. For beginners, it’s one of the most practical methods available. Known as vac-aging or plastic aging, the process locks in moisture, reduces unwanted mould growth, and removes most of the ongoing maintenance required by waxing or natural rind ageing. It works best with hard and semi-hard cheeses, and getting good results comes down to using the right cheese, the right preparation, compatible bags and safe storage conditions.
To successfully age and mature cheese, you need to understand how vacuum packing works, how to prepare and seal it correctly, which bags to use, and how to monitor your cheese safely throughout the ageing process.
Quick guide to vacuum sealing cheese:
- Best for hard and semi-hard cheeses: cheddar, gouda, parmesan, colby
- Dry the surface before sealing; no excess moisture inside the bag
- Label every vacuum pack: cheese type, creation date and planned check date
- Store at or below 5°C in a fridge or cheese cave
- Not suitable for fresh, soft or blue-veined cheeses
Can You Age Cheese in a Vacuum-Sealed Bag?
Yes, hard and semi-hard cheeses can be aged in a vacuum-sealed bag. The cheese itself contains enough internal oxygen for ripening to continue in the bag, and the sealed environment slows unwanted mould growth and prevents the rind from drying out unevenly.
The main trade-off is flavour. Vacuum packaging limits the cheese’s exposure to its surrounding environment, including the humidity, airflow, and microflora of a cheese cave, which changes how it develops compared to naturally aged cheese. Many home cheesemakers manage this with a hybrid approach: ageing the cheese unwrapped for a few weeks to develop rind character, then vacuum-sealing it for the remainder of maturation.
For store-bought and homemade cheese alike, vacuum packaging offers a cleaner, lower-maintenance path to maturation and longer storage.
Vacuum Sealing vs Waxing vs Natural Rind Ageing
For a home cheese maker, the choice between vacuum sealing, waxing and natural rind ageing comes down to maintenance, environment and the type of cheese you’re making.
| Method | Best For | Main Benefit | Main Limitation |
| Vacuum sealing | Hard and semi-hard cheeses | No humidity control needed; clean, consistent seal | Less rind development; different flavour profile |
| Waxing | Traditional hard cheeses | Waxed cheese ages with some breathability | Waxing is messy; mould can develop under wax if the seal is imperfect |
| Natural rind | Artisan-style cheese | Full flavour from the ageing environment | Requires humidity control, regular turning and mould monitoring |
| Cheese paper or wrap | Opened portions | Short-to-medium fridge storage | Not suitable for longer maturation |
Waxing requires melted cheese wax, multiple dipping coats and regular seal checks throughout ageing. Even a well-waxed cheese can develop mould beneath the coating if a fault or crack forms, and waxing becomes increasingly time-consuming when working with more than one or two wheels. Many home cheesemakers switch from waxing to vacuum sealing after running into cracked wax or mould beneath the coating. Natural rind ageing calls for a properly controlled cheese cave, consistent humidity levels and hands-on attention throughout, and vacuum sealing removes most of that ongoing work. That said, waxing still has a place for shorter maturation periods and produces genuinely good results in the right hands.
Which Cheeses Are Best Suited to Vac-Aging?
Vacuum bags work best with firm, relatively dry cheeses. Excess moisture inside the bag can compromise the seal, encourage mould growth and leave you with a softer, wetter result than intended.
Suitable for vacuum sealing:
- Hard cheeses: cheddar-style, parmesan-style, aged gouda-style
- Semi-hard cheeses: Colby, Edam-style, farmhouse cheddar
- Store-bought block cheese for portioning and cheese preservation
- Shredded cheese portions for fridge or freezer use
- Homemade firm cheese after pressing, brining, and air drying is complete
Not suitable for longer maturation:
- Fresh cheeses: ricotta, cottage cheese, fresh mozzarella
- Soft rind cheeses, such as brie and camembert, need oxygen to ripen and can become overly acidic in a vacuum bag
- Blue-veined cheeses: mould development requires air exposure
If you’re working with raw milk cheese, exercise extra caution. Raw milk dairy carries a higher risk of harmful bacteria, including Listeria and is not recommended for pregnant women, the elderly or young children.
Food Safety Before Vacuum Sealing Cheese
Dairy products are generally classified as potentially hazardous foods under Australian food safety standards and should be stored at 5°C or below to minimise bacterial growth. Vacuum sealing may help extend shelf life, but it does not remove the need for refrigeration for products that require chilled storage.
Before sealing any cheese:
- Use clean hands, clean tools and clean bags to avoid cross-contamination
- Never seal spoiled cheese; sealing locks in the problem rather than correcting it
- Remove any surface moisture before placing cheese in the package
- Label every package: cheese type, date sealed and planned check date
- Check your fridge or maturation fridge temperature with a thermometer
- Discard any package showing gas build-up, slimy texture or a failed seal; if a bag releases an ammonia-like odour (this can smell like urine, cat litter, sweat, and pungent hair dyes) when opened, air the cheese for a few hours and reassess before consuming
For food businesses, Food Standards Australia New Zealand (FSANZ) provides guidance under Standard 3.2.2 for storing potentially hazardous dairy foods.
Vacuum-sealed cheese must always be refrigerated. Room-temperature storage is not safe, particularly in Australia’s warmer climates.
How to Prepare and Vacuum Seal Cheese Step by Step
Getting the prep right matters as much as the seal itself. Sealing wet or underprepared cheese is the most common reason vacuum-packed cheese fails.
Prepare the cheese:
- Confirm the cheese is a hard or semi-hard variety suitable for vacuum sealing
- For homemade cheese, complete all pressing, brining and rind drying steps; the surface must be dry to the touch before you vac pack
- Wipe away excess moisture with a clean, dry cloth
- Pre-season the rind if needed; a light brine wipe helps manage surface bacteria before sealing
- Portion into practical sizes and check that the bag has adequate headspace around the cheese
Seal the cheese:
- Select the correct bag type for your machine (see guide below)
- Place cheese inside without touching or smearing the seal area
- Use a gentle or manual vacuum mode for softer semi-hard cheeses if your vacuum sealer offers it; the VS105 and VS603 both include a pulse function that gives you control over vacuum pressure
- Create a clean, even seal. Use a double seal for longer maturation, larger pieces or firmer-edged cheese.
- Label the package immediately: cheese type, date sealed, planned check date
- Store in the fridge or cheese cave straight away
- Turn and check the seal every one to two weeks during early maturation
After opening: Let the cheese rest for a few hours before eating so it can find equilibrium in the new environment and air out any stronger flavours built up during the sealed ageing process. A small amount of whey in the package is normal; the pressure of vacuum sealing draws a little liquid from the cheese. Significant pooling, bag swelling or a strong off-odour needs careful assessment before consuming.
Important: the VS105 and VS603 are rated for dry foods only. If your cheese is weeping visible liquid before sealing, pat it thoroughly dry before placing it in the bag to avoid liquid being drawn into the machine.
Choosing the Right Vacuum Sealer Bags for Cheese
The bag type must match your machine, and using the wrong bag is a common, easily avoidable mistake.
For domestic out-of-chamber vacuum sealers such as the Pac Food VS105 or VS603, you must use microchannel bags or embossed microchannel bags. The textured channel structure allows the external suction sealer to draw air out through the bag. Standard flat commercial vacuum sealer bags will not work in these machines.
For commercial chamber vacuum sealers, flat commercial bags are the right choice. Pac Food stocks 70-micron and 100-micron commercial vacuum sealer bags for in-chamber machines used in commercial kitchens.
Pac Food’s standard micro channel bags are 85-micron, BPA-free, food-safe, and designed to work with every vacuum sealer on the market. The embossed micro channel bags are 100 microns, offering a stronger barrier and faster vacuum speed, making them a good choice for firmer cheeses with harder edges.
| User Type | Machine Type | Recommended Bag |
| Home user | Domestic out-of-chamber (VS105, VS300, VS603) | Micro channel bags or embossed micro channel bags |
| Frequent home user | Domestic/semi-commercial | Embossed micro channel bags or rolls |
| Commercial kitchen | Chamber vacuum sealer | 70 or 100 micron commercial vacuum sealer bags |
The VS603 is Pac Food’s best-selling domestic model, suited to medium-to-heavy home use and small-scale production. The VS105 is the more economical option for smaller and less frequent home use.
How Long Can You Mature Vacuum Sealed Cheese?
Maturation time depends on cheese type, moisture content, salt, acidity, storage temperature and hygiene throughout the process. Some hobby cheesemakers vacuum-pack after rind formation and age for several months with good results; others use it primarily for shorter-term cheese preservation and storage rotation of store-bought blocks.
A practical starting point is to check the package weekly for the first month, then fortnightly once the seal and cheese behaviour appear stable.
Signs the cheese is maturing well:
- Seal remains tight with no swelling
- No significant liquid pooling inside the package
- Firm, consistent texture when pressed
- Cheese-like aroma after a short airing period when opened
Warning signs to act on:
- Bag swelling or gas build-up
- Slimy or unusually soft texture
- Leaking or failed seal
- Strong rotten or ammonia odour that doesn’t clear after airing
- Unusual discolouration or visible mould inside the sealed package
If in doubt, throw it out!
Common Mistakes When Vacuum Sealing Cheese
- Sealing before the surface is dry is the most common reason vacuum packing cheese fails
- Using flat commercial bags in a domestic out-of-chamber vacuum sealer
- Forgetting to label every package with the cheese type and date
- Leaving cheese at unsafe temperatures before or after sealing
- Over-vacuuming softer semi-hard cheeses, compressing and damaging the texture
- Using bags too small for the cheese, forcing it against the seal area
- Skipping regular bag checks after sealing
- Assuming vacuum sealing will correct poor hygiene or salvage already-spoiled cheese
- Treating waxed cheese, natural rind cheeses and vacuum-sealed cheese the same; each ages differently and needs different handling
Is Vacuum Sealing Cheese Worth It?
For most home users, yes. Vacuum sealing is practical for reducing waste, portioning bulk cheese, extending freshness, and simplifying cheese ageing without the preparation and mess of waxing. It’s also a solid option for small food businesses that need clean, consistent, labelled packaging.
It’s not the right method for every type of cheese, but for firm varieties handled properly, vacuum sealing is a reliable and accessible food preservation method for Australian home cooks and hobby cheesemakers.

Frequently Asked Questions
Can you vacuum-seal cheese to age? Yes. The process is known as vac-aging or plastic aging. Hard and semi-hard cheeses continue to ripen in the bag, using the oxygen and active bacteria already present in the cheese. The flavour profile will differ from waxed cheese or natural rind ageing, but the cheese aging process does occur.
How do you age cheese at home for beginners? Vac-aging is one of the most practical starting points for firm cheeses. Dry the surface of the cheese, place it in a micro channel vacuum bag, create a clean seal, label the package with the date, and store it in the fridge at 5°C or below. Check it regularly for seal integrity, excess moisture, gas build-up, unusual odours or mould.
How long will cheese last if I vacuum-seal it? There’s no fixed answer. It depends on the type of cheese, moisture level, salt content, acidity, and storage conditions. Monitor every package for swelling, failed seals and off-odours rather than relying on a set timeframe.
Is it a good idea to vacuum-seal cheese? For hard and semi-hard cheeses, yes. Vacuum sealing prevents unwanted mould growth, eliminates the need for strict humidity control, and simplifies cheese preservation compared with waxing or natural rind methods. It’s not suitable for every type of cheese, but for most firm varieties, it’s a practical, effective option.
