So I bought cobblestone hunting about six weeks ago and fell in love with it. To me, it has one of the best lemon citrus Tangy elements to a blend. But what I’m asking is I only smoke it about once or twice a week and then put it back into the mason jar. I packed a bowl and smoked it today and it completely tastes different. The tang is gone and now it taste more like a dark fired. Is there something that I’m doing wrong storing my tobacco or is this normal?
