OK, I have a friend who has just recently moved house. During his packing/unpacking he discovered a long forgotten bag. In this bag was a quantity of Liberty cap's which must be at least 8 years old... maybe more but I'm guessing probably not less! I have no idea whether these things have a shelf life do to speak. They were dried out at the time of picking very carefully and wrapped in paper for safe keeping... as far as he can tell after looking them over they look no different now to what they did when he packed them. I mean they were really dry. There are no signs of mold on any of the ones he's checked. So, question is, would these still be OK to have a go at or is there a chance something has happened to them over that time to make you think he should just bin them?
