Tips on How to Pick, Prep, and Roast Your Own Coffee Beans

When we visited the Shim Coffee Farm in Kula, Maui last month, farmer Casey Shim greeted us with a big, friendly smile. He wanted to share his knowledge of processing organic coffee with us.
His one-man farm operation keeps Casey busy throughout the summer. He’s got a thorough operation at his farm, and the results he produces with Maui-grown coffee are simply delicious.Here are a few of his top tips to make coffee at home with homegrown coffee plants. (This is not a step-by-step guide; you’ll have to meet with Casey Shim and take a Maui coffee farm tour for the complete directions!)
