In any coffee production, it is easy and common for toxins and errant chemicals to enter the growing and production areas. As a result, commercial large scale coffee producers over roast their beans to cover the bad effects of contamination. We have laboratory testing of our products for cleanliness so you can be assured that you are purchasing only the cleanest products and nothing else. That is also why we can roast our beans to a medium amount which maintains the rich flavor and aroma of the specialty product.
