Just learned that green coffee loses about 20% of its weight during roasting and I had no idea
I was poking around on Sweet Maria's site last week and read that figure, that you lose roughly 15 to 20 percent of the bean weight when you roast. So when I buy 5 pounds of green beans for $30, I am really paying for about 4 pounds of drinkable coffee. I just always assumed the weight stayed the same and wondered why my 1 pound batches looked so small in the jar afterward. Does anyone actually weigh before and after, or am I the only one who never bothered to check?
