We offer our 100% Kona Coffee on the top 3 sizes to a minimum of a No. 1 grade but offer our beans on screen sizes to appeal to the taste and price range of the buyer. Our online store offer green bean graded for the home roaster but for the coffee shop or retailer, we will gladly offer a sample of the bean size and grading standards they require. Please remember that the grading standards can change within the Dept. of Agriculture in Hawaii but the screen size is based on the actual size of the bean. Our opinion is that we will guarantee our product to the customers request but not all volumes or screen sizes are available in infinite quantities. Please express your interest by late summer or early fall to ensure that we can supply you as we do not always carry year round supply of green bean to purchase. The commercial customer may want to email or phone in advance of your order.
