For this episode, Kenneth sat down with Eric Stone of Mudhouse Coffee Roasters to talk about the art and science of roasting. They recorded this episode in Boston while competing as finalists to determine who's the best specialty coffee roaster in America.

Eric and Kenneth discuss the subject of roasting coffee in-depth including the different types of coffee roasters, how temperature imoacts the roast, the roast curve, halogen roasting, first and second crack, and tipping just to name a few of the subjects covered. They explain how the look, smell and even the noise the beans make when in the roaster at the various stages of the roast impact your cup of coffee.

KEY TAKEAWAYS

• The way your coffee is roasted has about a 30% impact on how it tastes. 
• Small sample roasters are used to evaluate new batches of beans, identify the flavor profile, and manipulate those flavors to create the best overall taste.
• The same bean, roasted in different ways, can taste extraordinarily different.
• A new variable in roasting is emerging which uses halogen as the heat source.
• The roast profile curve is the order in which key stages of the roasting process occur - Kenneth and Eric walk you through this curve.
• Light roasts are more sensitive to changes in the roasting process than dark roasts.
• It is particularly important to cool the beans down as fast as possible to stop the cooking process at the right temperature once roasting is complete.
• The water content and density of the bean have a significant impact on your roast.

BEST MOMENTS

‘Our sample drum roaster also has airflow moving through the drum, so you´re roasting with both convection and conduction. ´

‘There are countless ways you can manipulate the flavor of a coffee.’

‘Once you're past the first crack, if you apply too much heat you run the risk of making some roaster errors.’
