I have no idea how old this is but I suspect several years. It was given to me. Steeped in a small cup to see if it survived. At first I thought it was too far gone but as it cooled the peppermint came through nicely. Really not getting the spearmint but I prefer it that way. The rosehips and hibiscus give the cup color and only the slightest touch of tart. It would be interesting to know how this tastes fresh. I probably would not buy a box but will definitely finish this one.
