Tea bags found tucked away in kitchen cupboards past their expiration date are generally safe to drink if stored correctly, according to experts from specialty retailers The Republic of Tea and Brooklyn Tea.
Speaking to lifestyle outlet Martha Stewart, tea specialists explained that consumers who stock up on different varieties often discover long-expired boxes. However, an expiration date marks when a product passes its peak quality rather than when it becomes dangerous to consume. Over time, tea gradually loses its aroma and flavour, resulting in a less vibrant cup.
Jamila and Alfonso Wright, co-founders of Brooklyn Tea based in New York, stated that most tea varieties can remain relatively rich for up to two years when stored in an airtight container away from sunlight and moisture.
The Republic of Tea, founded in 1992, and Brooklyn Tea are American specialty tea companies known for loose-leaf blends and consumer tea education.
Signs of tea spoilage
The Wrights noted that manufacturers calculate expiration dates to signal peak quality. Consumers should check for physical signs of spoilage rather than relying solely on printed dates.
Kristina Tucker of The Republic of Tea stated that tea should be thrown away if it develops an off or musty smell, or shows any signs of mould, discolouration, or moisture damage. If the tea looks and smells as expected, it can usually be brewed safely.
The Wrights warned that using tea in poor condition or storing it incorrectly carries risks. Using a wet spoon in a container of loose tea can cause mould to grow quickly, making the product potentially dangerous.
After brewing, tea that appears faded, lacks aroma, and tastes watery should be discarded, according to the Wrights. They added that old tea is well suited for compost.
Best storage methods
Proper storage preserves flavour and extends shelf life. Tucker advised storing tea bags in a cool, dry place away from heat, moisture, and direct sunlight.
Tucker explained that moisture is the primary threat to tea quality because damp tea bags can grow mould and should not be consumed. She added that airtight packaging plays a vital role in protecting delicate flavours and aromas.
The Wrights noted that original packaging is suitable if it provides adequate protection against external elements. However, once a package is opened or if the original box offers insufficient protection, transferring tea to an opaque, airtight container keeps it fresh for longer.
