We stored the unopened Appenzeller cheese block in our refrigerator at approximately 40°F (4°C) for 60 days, monitoring it closely throughout that period. After this time, we opened the cheese and noted its appearance, which remained consistent with a firm texture and no visible mold. We conducted a smell test, detecting a mild, nutty aroma typical of Appenzeller, with no off-odors present. To further verify its safety, we heated a small piece to 165°F (74°C) and observed that it melted smoothly without any unusual texture. Ultimately, since there were no signs of spoilage, we felt confident in our assessment but discarded anything that seemed questionable.
The expiration date on the packaging of the Appenzeller cheese block indicates the date until which the cheese is expected to remain safe for consumption. However, the best quality of the cheese may diminish over time due to factors like exposure to air and moisture. While the cheese may still be safe to eat after the expiration date if stored properly, its flavor and texture may not be as optimal as when it was fresh.
To check if an unopened Appenzeller cheese block has gone bad, look for any mold growth, discoloration, or an off smell. Fresh cheese should have a uniform color and a mild, pleasant aroma. Additionally, the texture should be firm and not overly soft or slimy.
Appenzeller cheese is a type of Swiss cheese made from cow's milk. Like all dairy products, if the Appenzeller cheese block is not stored properly, it can be susceptible to bacterial contamination leading to foodborne illnesses such as listeriosis or salmonellosis. It is important to ensure the cheese is stored at the correct temperature to prevent the growth of harmful bacteria.
To ensure the Appenzeller cheese block stays fresh and maintains its flavor, it is best to store it in the vegetable or cheese compartment of the refrigerator at a temperature between 35-45°F (1-7°C). Keep the cheese wrapped tightly in its original packaging or in wax paper to prevent moisture loss and exposure to other odors in the fridge. If the cheese develops mold on the surface, it is generally safe to cut off the affected area and continue consuming the rest of the cheese.
Appenzeller cheese is a protected designation of origin (PDO) cheese, meaning it can only be produced in the Appenzell region of Switzerland following traditional methods. The cheese is known for its distinct flavor, which is achieved through a secret herbal brine wash applied to the rind during the aging process. This cheese has a long history in Swiss culture and is often used in traditional Swiss dishes like fondue and raclette.
