"I wanted to order Colombian although they were out, so I chose Costa Rica montano jaguar aerobic as a replacement. I am very satisfied with the coffee! It is well worth investing in, probably a lot better than the other kind. So smooth and flavorful!"

"Great customer service and product. Highly recommended"
"Thank you for your help with my roaster. It works well now. The coffees are really good. I am enjoying them each morning."
"I’m excited to try fermented. All ice roasted has been washed. As I was roasting the first thing I noticed was a few beans roasting quicker than other. I adjusted my roast. Agree I’m setting beans that are many different sizes."
