From a friend, this is what Hawaii Coffee Company is doing at the treehouse in Capt. Cook
Listed cherry price is $1.10
If you have 0%-6% cbb, he will give you an extra $0.15 per pound
If you have 7%-20% cbb, he will pay flat $1.10
If you have >20% cbb, he will dock you $0.15
They are sampling every batch of coffee coming in and my friend was told "it's a work in progress" and there will be ways to appeal if you don't like the price.
HCC also gives 1 bag of fertilizer for every 1000 pounds. This may sound like a good deal but only adds $0.02 per pound to the cherry value.
