"Drove 20 minutes out of the way to end up at an empty building not sure what this place is, but it definitely is not open during the post hours. No signs no activity. This place is definitely suspect."

"What a wonderful facility for teaching about coffee. If you have a chance to register for their class, give it a shot. They do a great job of teaching about where coffee comes from and the sustainability practices involved. The staff was very knowledgeable and cordial. This place is where the roasting (I believe they have larger roasting facility down the street), training, and R&D occurs and is NOT a Crimson Cup Coffee shop. This is the place that supports the Crimson Cup Coffee shops."

"Joe at Crimson Cup kindly met with us for a Roasting Fundamentals class. He taught us different roast profiles on the sample roaster, and how different origins and bean processing impacted the roast. Afterward, we cupped the results. Using the sample roaster, plus learning from Joe's vast knowledge and expertise was a wonderful experience. He went out of his way to accommodate us and we walked away with some awesome samples and Crimson swag. Wonderful experience."

"Attended Coffee ColLab in 2018 and it was a real treat. The lab does some pretty cool stuff and all things related to coffee. They also offer educational classes on coffee"

"Went to the Crimson Cup for the 2nd annual Columbus Coffee Lab tonight, had a great time! My wife came with me and also enjoyed it..."
