Grated Romano cheese can go bad, but its shelf life depends on several factors, including storage conditions, packaging, and maintenance. Properly stored unopened Romano cheese will last for about 7 to 9 months in the refrigerator, while opened cheese should be used within 3 to 4 weeks. Grated Romano cheese sold unrefrigerated can last for 10 to 12 months in the refrigerator after opening, and freezing it extends its shelf life to 12 to 18 months or even longer. Signs of spoilage include mold, an off odor, changes in texture, and a strong smell.

What You'll Learn
How long does grated Romano cheese last in the fridge?
Grated Romano cheese will last in the fridge for about 5 to 7 days. The precise answer depends on storage conditions. To maximize the shelf life of opened grated Romano cheese, it should be wrapped tightly in plastic wrap or aluminium foil and stored in an airtight container in the refrigerator. This will prevent it from drying out or absorbing odours from the fridge.
Romano cheese is a hard, granular, and salty Italian cheese traditionally made from sheep's milk, though variants made from cow's milk (Vacchino Romano) and goat's milk (Caprino Romano) are also available. The most famous and authentic variety is Pecorino Romano, produced primarily in the regions of Lazio, Sardinia, and Tuscany.
Like any other dairy product, hard cheeses eventually spoil. However, the low water content in hard cheeses like Romano helps them last much longer than soft cheeses. Unopened Pecorino Romano cheese can last for several weeks, and in some cases, even months beyond its "best by" or "use by" date.
Properly stored, an unopened chunk of Romano cheese will last for about 7 to 9 months in the refrigerator, depending on the sell-by date. Once opened, it's best to use it within 3 to 4 weeks.
If you want to extend the shelf life of your grated Romano cheese, you can freeze it. Place the grated cheese in covered airtight containers or heavy-duty freezer bags. Frozen Romano cheese may lose some of its texture and flavour, so it is best suited to cooked dishes such as sauces, soups, and casseroles. Properly stored, grated Romano cheese will maintain its best quality for about 12 to 18 months in the freezer, but will remain safe beyond that time.

Signs of Spoilage
It is important to regularly check your stored grated Romano cheese for any signs of spoilage. The cheese may go bad due to exposure to air, moisture, temperature fluctuations, or improper storage. Here are some signs that your grated Romano cheese may have gone bad:
- Mold: If you notice any excessive mold or mold of an unusual colour, such as pink, green, or black, discard the cheese immediately.
- Odour: If the cheese develops an unpleasant, sour, or off-putting smell, it has likely gone bad and should be discarded.
- Texture: If the texture of the cheese becomes excessively soft, gooey, crumbly, or slimy, it may have deteriorated and should be discarded.

Signs that grated Romano cheese has gone bad
Grated Romano cheese can go bad, and there are several factors that can contribute to its spoilage, such as exposure to air, moisture, temperature fluctuations, and improper storage. The shelf life of grated Romano cheese can vary depending on storage conditions, packaging, and maintenance. Here are some signs that your grated Romano cheese has gone bad:
Mould
While some cheeses have mould as part of their natural ageing process, an excessive amount of mould or mould of an unusual colour may indicate spoilage. If you notice pink, green, blue, white, or black mould on the cheese, it is best to discard it. Don't be tempted to cut off the mouldy part and eat the rest, as mould can produce harmful toxins and bacteria.
Off Odour
If the grated Romano cheese emits an unpleasant, sour, or otherwise off smell, it is likely a sign of spoilage. Fresh Pecorino Romano should have a distinctive nutty aroma, and any deviation from this could indicate deterioration.
Changes in Texture
If the texture of the grated Romano cheese becomes excessively soft, gooey, crumbly, or slimy, or hard, it may be a sign that the cheese has gone bad.
Appearance
Romano cheese that has gone bad may also exhibit changes in appearance, such as darkening in colour or developing a strange appearance.
It is important to note that grated Romano cheese can be stored in the refrigerator for 5 to 7 days, and its shelf life can be extended by freezing it in airtight containers or freezer bags. However, freezing may cause changes in texture and flavour, making the cheese more suitable for cooked dishes.

Can you freeze grated Romano cheese?

Romano cheese has a lower moisture content than other cheeses, which means it will freeze and thaw with little impact on its texture or taste. If you choose to freeze grated Romano cheese, it can last up to 6 months in the freezer.
When thawing frozen grated Romano cheese, it is best to let it defrost slowly in the refrigerator. Once thawed, the cheese may crumble more quickly, so it is ideal when used in recipes that call for grated or shredded cheese.
