As long as it doesn’t turn to dust before I do. The race is on…
An addendum to this exchange. I had the need to go through my various holdings in search of a specific blend I was trading away, and came across the 1lb bag of Vintage Syrian that I had forgotten about. So, we're looking at a 5 year old bag. It felt a bit crunchy when I pressed on it and I feared that it had indeed completely dried out in the bag, which would not be a good thing.
I opened the bag and the contents were extremely dry, but not, thankfully, completely dired out. I could feel the faint presence of moisture, so I rehydrated with distilled water, which went very well, and now the contents are jarred up.
