Four colombian green somewhere in the 3 to 4.50 range. That's also single origin. Excelso. If you have more of a generic colombian it'll be less. Add on about 1.25 /lb for a contract roast.
For kenyan tt thru ab 3.50 to 5.65. Add the roast cost on to those. Again these are for a single origin...
Where is the coffee they're getting from? Also is it arabica or robusto? Also, what grade are they getting from those places? All of all of that is factored in as well as how much the roaster is able to roast at one time to keep the labor cost of roasting per pound low
