"I have been ordering coffee from Calibration Coffee Lab for a while now, and it’s hands down some of the best I’ve ever had. The attention to detail in the roasting process is evident in every sip. Each blend and each single bean coffee has a distinct flavor profile that clearly comes from a deep understanding and passion for the art of roasting. If you're serious about your coffee, this is a must-try!"

"This is the factory where the beans are roasted, and isn't a customer location except for pickup orders that have been pre-arranged. However, Calibration coffee is where I get my locally-roasted coffee beans, and in my opinion, are the best locally roasted beans you can get in Greenville! My favorites (that I've tried so far) are the Elevate and then the Guatemala Quetzal, but you can't go wrong with any of the options!"

"Alex has a talent for emphasizing distinct flavor profiles in his batches. His descriptions are spot on. You don’t need specialized brewing equipment to appreciate the nuance in his blends/roasts."

"Knowledgeable guy who goes out of his way to accommodate orders. Creates some really good coffee."

"Delicious coffee and love that is is locally roasted."
