Safety first: This guide provides general information. When in doubt, throw it out! Trust your senses and err on the side of caution. If something smells, looks, or tastes off, don't consume it.
Homemade, Refrigerator3-6 months
Signs of Spoilage
Mold growth (fuzzy, discolored spots on the surface or around the rim), yeast growth (bubbly appearance, fermented/alcoholic smell), significant change in color, off-smell (sour, musty, putrid, or unusually vinegary beyond its normal aroma), unusual texture (gummy, stringy, excessively watery, or solidified with lumps).
How to Check
-
Visual: First, check for any mold on the surface or around the rim. Look for cloudiness or unusual particles.
-
Smell: Sniff for any off-odors like sourness, yeastiness, or anything unpleasant.
-
Texture: Observe the consistency. It should be syrupy. If it's too thin, stringy, or lumpy, it's a sign of spoilage.
Storage Tips
Store in a clean, airtight glass container. Ensure the container is thoroughly sterilized before filling to minimize bacterial introduction. Avoid introducing contaminants by using clean utensils. Refrigeration is essential for homemade reductions due to the lack of commercial preservatives.
Unopened Commercial Bottle, Pantry1-2 years (or 'best by' date on packaging)
Signs of Spoilage
Damaged seal, leakage, unusual cloudiness or sediment (if not characteristic of the product), strong off-odor if seal is compromised.
How to Check
Check the 'best by' or 'expiration' date. Visually inspect the bottle for any signs of tampering or damage to the seal. The liquid should be clear or consistent in appearance with the product type. If the seal is bulging or compromised, do not use.
Storage Tips
Store in a cool, dark place away from direct sunlight and heat sources to maintain optimal quality and prevent premature degradation.
Opened Commercial Bottle, Refrigerator6 months - 1 year
Signs of Spoilage
Mold growth (fuzzy, discolored spots on the surface or around the rim), yeast growth (bubbly appearance, fermented/alcoholic smell), significant change in color, off-smell (sour, musty, putrid, or unusually vinegary beyond its normal aroma), unusual texture (gummy, stringy, excessively watery, or solidified with lumps).
How to Check
-
Visual: Inspect the surface and sides of the bottle for any mold, cloudiness, or suspended particles that weren't there originally.
-
Smell: Open and sniff carefully. A fresh reduction has a rich, sweet, tangy aroma. Any sour, yeasty, or unpleasant smell indicates spoilage.
-
Texture: Pour a small amount. It should have a syrupy consistency. If it's unusually thin, stringy, or has solidified with lumps, it's likely spoiled.
Storage Tips
Always ensure the lid is tightly sealed after each use. Use clean utensils or pour directly to avoid introducing contaminants. Refrigeration significantly extends its shelf life and prevents mold/yeast growth once opened.
