Proper storage is crucial for maintaining black tea's flavor and freshness:
Quality black tea can last 18-24 months when stored properly. Signs of spoilage include musty smell, visible mold, or loss of aroma. Tea bags typically have a shorter shelf life than loose leaf tea due to their smaller particle size. Consider using glass or ceramic containers with tight-fitting lids, and avoid storing tea in the refrigerator as condensation can affect quality.
