The Academy of Coffee Excellence is the East Coast authorized Diedrich Training Program. Our program is a very comprehensive course methodically taking you through the life-cycle of the coffee from seedling to the processing to the basics of roasting and most importantly profile roasting.

Every coffee is unique, as noticed from the varietal to the elevation at which the coffee is grown, cultivation techniques, processing methods, bean size and density as well as moisture content. Every coffee has its own distinctive characteristics. In recent years, both growers and mills alike have been experimenting with innovative new processes which are changing the world of coffee. The greater selection of estate coffees, micro lot and Cup of Excellence coffees are the results of these efforts. With hands-on roasting you will learn the fundamentals of roasting and the fine points of developing roast profiles. A refined roast profile brings out a coffees true expression, which the producers so diligently work to achieve.

    You will gain an appreciation for the care and the hard work that goes into every step of the process and understand the relevance of a roast profile.
    You will learn the fine points of controlling the coffee and the stages of the roast which are critical. You will learn techniques to enhance a coffees flavor and how to identify roast imperfections and avoid them.
    In the Diedrich roasters, you can fine-tune the balance of convective, conductive heat throughout the roast. You will learn how these distinctly different types of heat are adjusted and when to adjust them during the roast, to best suit the coffee.
    Applying heat to coffee starts an extremely complex chain of chemical and physical changes. How these chemistries transform and react is dependent on the type of heat and the rate at which heat is applied. You will learn about the factors which affect how the heat migrates into the bean and how the coffees react to heat.
    You will learn how the flavor nuances change when manipulating the chemistry in different ways. By methodically experimenting with roast color, time to the color, varying temperature profiles and how much air is drawn through the drum at different stages of the roast, you refine the roast profile and the coffees flavor profile.
    You will learn how to work with an importer to ensure that you are buying the best beans for your customers. You will learn the ways to purchase your beans including the spot market and forward purchasing. The majority of the time of our program is hands-on roasting and cupping. Attendees will first get acquainted with the roaster and the fundamentals of roasting, then progress to keeping the coffee on a profile. We have an IR-5 in our training room so you will have ample opportunity to test and develop your skills.
    You will learn the fundamentals of cupping coffees to be certain that you can pinpoint the best green beans from your importer and growers as well as monitor your profile development to capture your coffee’s perfectly nuanced flavors.

    You will learn about a typical day in the life of a roaster including forms and documentation, time management, working with your customers, and other essential elements for success.

Each day, morning coffee, fruit and baked goods are provided. Lunch and snacks are also provided each day.
