Storage Shelves and Supports
Proper storage shelves and supports serve as the foundation of a successful cheese cave setup. You'll need to use a combination of tight pine and ash wood boards, with pine being particularly effective for moisture absorption during the drying process.
Select boards that are 3/4" thick for cheeses under 10 pounds, but opt for thicker shelves if you're aging heavier varieties.
When constructing your shelves, pre-drill holes and use small brass nails for assembly. You can incorporate dowel rods for sides and supports, ensuring the wooden components have been air-dried for several seasons before use.
Avoid pine boards with numerous knots or resin spots, as these can stain your cheese.
To maximize airflow, maintain adequate spacing between cheese rows and walls. Place cheese mats underneath each wheel to promote proper air circulation, especially vital for aged cheeses with firm rinds.
If you're planning to stack cheeses, only do so with very firm, dry varieties. For efficient transport, consider building deeper racks that can hold multiple boards at right angles.
Remember to keep proper spacing between shelves to prevent mold growth from poor air circulation.
Humidity and Temperature Management
Successfully aging cheese depends heavily on precise control of both humidity and temperature levels within your cheese cave.
You'll need to maintain humidity between 70% to 90% and keep temperatures at 10-13°C (50-55°F) for ideal results. Install a digital hygrometer thermometer to monitor both conditions consistently.
To manage humidity, you've got several effective options. You can use humidifiers with ultrasonic misting technology, set up a fountain mister, or place water trays in your cave.
For precise control, consider using a saturated salt solution like sodium chloride, which maintains humidity around 75%. If you need quick adjustments, damp paper towels or sponges can boost moisture levels temporarily.
Temperature control starts with proper cave location – choose a spot that minimizes solar gain, preferably on the north side of your structure.
You'll want to insulate walls and ceilings thoroughly to maintain stable temperatures. Install a temperature controller to regulate conditions automatically, and if necessary, add heating or cooling units.
Don't forget to use containers with adjustable vents for your cheese storage, and clean your cave regularly to prevent unwanted mold growth.
Proper Airflow and Ventilation
Your cheese cave's ventilation system needs to move air gently from bottom to top, using PVC pipes and fans to control the flow without drying out your cheeses.
You'll want to install inlet pipes buried in the ground to pre-cool incoming air, along with outlet pipes fitted with goose neck caps to manage air exchange effectively.
Opening the door periodically and using filtered vents will help maintain fresh air circulation while removing unwanted gases and preventing mold buildup.
Airflow Direction and Speed
Inside a cheese cave, air movement and direction play essential roles in successful aging. You'll want to maintain a gentle breeze that's strong enough to prevent mold buildup but not so powerful that it dries out your cheese. The ideal air velocity typically ranges from 0 to 1.3 feet per second, depending on your cheese type.
To achieve proper airflow, you can use small computer fans or muffin fans if your humidifier doesn't include one. Position these to create consistent air movement across each cheese piece, and remember to rotate your cheeses on the racks regularly to prevent dead spots.
The air should flow evenly throughout your cave, avoiding any temperature or humidity stratification.
You'll need to exchange stale air with fresh air to remove CO2 and ammonia buildup. For small caves, opening the door once or twice daily is sufficient. In larger setups, consider installing filtered air intakes. You can even use buried PVC pipes to bring in geothermally regulated fresh air.
The key is maintaining uniform conditions while ensuring your cheeses receive adequate ventilation without experiencing excessive air movement.
Ventilation System Components
A complete ventilation system encompasses several interconnected components that work together to maintain ideal cheese aging conditions.
You'll need to start with a filtered air intake system that prevents contaminants from entering your cave while allowing fresh air to circulate. Install high-quality filters at the intake points and make certain they're easily accessible for regular maintenance.
For the exhaust component, you'll want to incorporate vents that efficiently remove unwanted gases like CO2 and ammonia. Pair these with controllable fans that you can adjust based on your cave's specific needs.
You'll also need a reliable humidifier with a built-in fan to maintain proper moisture levels between 85-95%. Choose models that don't produce steam to avoid over-humidification.
Temperature control components should include an air conditioner or mini-split system with a Coolbot for precise regulation between 50-55°F.
