opened refrigerator5-7 days for optimal quality, up to 2 weeks if stored properly and no signs of spoilage.
Signs of Spoilage
Visible mold (white, green, black fuzzy spots, even small specks), sour, yeasty, or strong ammonia-like smell, slimy or excessively hard/dry texture, off-white or yellowish discoloration, or a chalky appearance.
How to Check
Visually inspect all the cheese for any mold growth. Perform a sniff test immediately after opening the bag or container – if it smells sour, rancid, like old milk, or has an unpleasant yeasty odor, it's likely bad. Touch a small amount – if it feels slimy or unusually hard and dry, discard it. For shredded cheese, if you find mold, it's best to discard the entire bag as mold spores can spread easily throughout due to its increased surface area. Do not taste if any of these signs are present.
Storage Tips
Re-seal the original bag tightly, or transfer the cheese to an airtight container or a heavy-duty freezer bag, pressing out as much air as possible. Air exposure is the primary enemy of freshness for shredded cheese. Avoid cross-contamination by using clean utensils and surfaces. Discard the entire bag if mold is found; unlike hard block cheese, you cannot simply cut off the mold from shredded cheese due to the high surface area.
unopened refrigeratorUntil "Best By" or "Use By" date on the package. Generally 1-2 months from purchase if well before the date.
Signs of Spoilage
Visible mold (white, green, black fuzzy spots), strong sour or ammonia-like smell, significant discoloration (yellowing or browning) through the packaging, or a bloated package (indicating gas production from spoilage).
How to Check
Always check the "Best By" or "Use By" date first. Visually inspect the cheese through the packaging for any signs of mold, discoloration, or sliminess. If the package appears bloated, it's a strong indicator of spoilage. Avoid purchasing or consuming if any of these signs are present.
Storage Tips
Store in the coldest part of your refrigerator (typically the back of the main compartment). Keep the package sealed until you are ready to use it to prevent air exposure and absorption of other odors.
freezer3-6 months for best quality; safe indefinitely but quality degrades over time.
Signs of Spoilage
Freezer burn (dry, discolored patches, often lighter in color), significant change in texture (becomes very crumbly, less pliable even after thawing), or an off-flavor after thawing (though usually still safe to eat).
How to Check
Visually check for freezer burn before and after thawing. After thawing, note the texture – it may be more crumbly and not melt as smoothly as fresh cheese. The smell should still be cheesy, not off or rancid.
Storage Tips
Freezing can alter the texture of shredded cheese, making it more crumbly and less smooth when melted. It's best used in cooked dishes where texture is less critical (e.g., casseroles, sauces, baked goods, pizzas). For best results, portion cheese into smaller, usable amounts before freezing. Store in airtight, freezer-safe bags or containers, pressing out all excess air to prevent freezer burn. Thaw frozen cheese in the refrigerator overnight before use. Do not refreeze thawed cheese.
