Metal Container Aged Cheese
Definition and Scope
Metal container aged cheese refers to cheeses matured within sealed metal vessels during the aging process. This technique creates a controlled anaerobic environment, distinct from traditional cloth-bound or wax-coated aging. It is a modern approach primarily used for certain cheddars and other firm, aged varieties.
The scope of this category is defined by the aging vessel’s material, not the cheese’s base milk or coagulation method. These cheeses are typically aged for several months to multiple years. The method aims to produce a consistent, moisture-retained product with a specific texture profile.
Production Process
Production begins after the initial cheese-making steps of curdling, cutting, and pressing. The young cheese is vacuum-sealed in a food-grade metal container, often a tin or specialized alloy vessel. This sealing process removes all air, preventing the growth of surface molds and controlling moisture loss.
The sealed containers are then transferred to aging caves or rooms with strictly controlled temperature and humidity. During this period, the cheese undergoes proteolysis and lipolysis in the absence of oxygen. This anaerobic environment significantly influences the final cheese’s flavor development and textural properties.
Sensory Profile
Metal container aged cheeses typically exhibit a smooth, firm, and sometimes slightly crumbly texture. They lack the rind development found in traditionally aged cheeses, resulting in a uniform appearance throughout. The paste is often denser due to retained moisture within the sealed environment.
Flavor profiles tend toward clean, sharp, and intensely milky or tangy notes. Common descriptors include pronounced acidity, nutty undertones, and savory umami characteristics. The absence of oxygen prevents certain flavor compounds from developing, yielding a different complexity compared to breathable-wrap aged cheeses.
Culinary Uses
These cheeses are excellent for table consumption, often served as part of cheese boards or for snacking. Their firm texture makes them suitable for grating over pasta, salads, and soups. The consistent quality and moisture content ensure reliable melting properties for cooked applications.
In food manufacturing, metal container aged cheeses are valued for their predictable flavor and functional performance. They are commonly used in processed cheese products, sauces, and ready meals. Their stability and longer shelf life make them practical for commercial kitchens and industrial food production.
Regional Examples
This aging method is prominently used for certain English-style cheddars, particularly those produced for export markets. Some New Zealand and Australian cheddar producers also employ metal container aging to maintain product consistency across long supply chains. These examples highlight the technique’s application in large-scale cheese production.
While less common in traditional European cheesemaking, some modern creameries in the United States have adopted this method for their aged gouda-style cheeses. The approach allows smaller producers to achieve specific textural goals while ensuring product stability during distribution to wider markets.
