Well, I would always sell a lb of green as a lb, and a lb of roasted as a lb. If I were to sell a lb of roasted, I would sell it on the weight of it roasted. LOL I am really starting to confuse myself :?
They are sold by actual weight, but remember that you lose 17% to 22% of the green weight or so during roasting. In other words a pound of green coffee beans will .85 lbs after it is roasted to a light roast and about .78 lbs or so very dark roasted. Does that make sense to you?
