I’m a home roaster and buy my green beans from a website called www.sweetmarias.com. Everything about this company is awesome but there’s guy there named Tom who knows probably as much as anyone could know about the entire coffee process from growing to wholesaling to roasting. He always travels to farms to meets with growers before purchasing. I guarantee if you get a hold of their customer service and explain your situation, you’ll be able to get a hold of someone there who can give you answers to most of your coffee-related questions.
