I have black tea bags, they’ve been stored in a sealed container, but the best by date is 2010 (13 years ago) can I still drink it safely? It’s decaffeinated blackberry sage tea. What signs should I look for that would tell me it’s unsafe?
How about 30 years? https://taiwanleaftea.com/rare-tea/30-years-aged-oolong-lao-cha As others have said, make sure it was dry the whole time.
I am not an expert but I love all kinds of teas. I wouldn't care about dried tea. But if the blackberry taste is a chemical substance, then I would pay attention to expiration dates... I would check the ingredients to find any chemical additives.In this case, if it is all natural I would think it is safe.
