I currently am using the Behmor 2000AB. It looks like a toaster oven but has a rotating basket inside. Mainly for coffee, but some folks roast cacao too.
I get green coffee beans from Sweet Maria’s…
I originally roasted small batches in my backyard with a pair of oven mitts, a wooden dowel for stirring, and a Hot Air popcorn maker with a Hurricane Lamp globe. Only problem is…you only roast about four ounces at a time.
Sweet Maria’s has an extensive collection of coffees…sourced from all over the world. They profile each type of bean they sell…to make it easier to find something you might be looking for.
