"This review is well overdue. You must I repeat you must get down to Celtic cup coffee for a true memorising coffee experience. Doug who is the owner, is so passionate and knowledgeable about coffee, the culture behind it and the origins of the beans he imports. This is the best true coffee experience in the DMV area. Not only is the price so affordable, the coffee beans sourced aren’t things you’ll find in cafes. They offer coffee flights that allow to experience the same bean at different roast to compare the flavour. Even the whole decor of the store you can see how much attention to detail and homage to the craft is made. Can’t recommend this Celtic coffee enough. This is a place to experience and learn about real coffee. You have the option to pick how your coffee is made whether drip, espresso etc."

"Would highly recommend the pour over. I enjoyed the Sumatra at medium-dark roast and bought a small gift bag of the fresh roasted beans. The cafe is clean and relaxed, friendly service and good vibes, so we stayed a few minutes to enjoy the coffee."

"Interesting concept. The very first thing I asked for a “cortado” but this place has no milk at all. It’s is strictly a coffee roaster place. So not a traditional coffee shop. I tried a flight of espresso and learned a lot about the roasting levels (light, medium and dark). I did not have my cortado with steam milk but it was a learning experience. I will come back to try more variety and buy some fresh roasted coffee bags."

"This was a true coffee experience. Doug was great at explaining how they roast their coffee and what kind of flavor component to expect. You'll only fine black coffee here, no artificial flavors, lattes or cappuccinos here. If you are a true black coffee lover, then this is a MUST try!! Allow yourself to spend a good 30-40 minute there for the coffee experience."

"I’ve been getting my custom-roasted coffee beans from Celtic Cup Coffee for the past four months and will definitely keep coming back. Doug, the owner, is truly passionate about coffee and incredibly knowledgeable about the entire process—from farm to cup. That expertise shines through in every roast and makes the experience here unlike anywhere else. Highly recommend!"
