What is it? The "cooked" coffee beans ready to be drank! Personal preference is key when deciding which coffee roast you may like. Generally split between Light, Medium, and Dark roasts. Lighter roasts are more acidic and dark roasts taste more like the average "coffee".
First, take a bunch of green beans.
Next, pour them into the coffee roaster and make magic happen!
Beautiful roasted beans!
My take on it...
I haven’t dabbled in roasting yet but I hope to one day. A massive amount of science, technique, math, and miracles involved!
