When I see people who have been in the same field for a long time and continue to put love and passion into their work, it gives me great motivation and inspiration as well. Thank you!"

May 12, 2026"It's more than a cup of coffee, it's an experience. Joachim loves people, talking, explaining, connecting. It felt more like a tour or a class than just a coffee shop. He travels often so it can be challenging to find a reservation."

Visiting them a few months ago was a dream come true. The atmosphere is fantastic and the coffee is amazing. Espresso, pour overs and freeze-distilled milk-based coffees I had were perfect. A huge thank you to Jo for having me. Your passion is limitless!"

Joachim is a master of his craft who genuinely takes the time to slow down, sit with you, and deconstruct your palate preferences before pulling a single shot. Instead of just ordering off a menu, we built a tasting journey together. He guided me through an incredible lineup of rare lots (the Panama Finca Deborah and Elida Estate selections on the board are world-class). The complexity in the cup was astounding—clean, vibrant, and evolving as it cooled. Joachim’s ability to curate a menu that evolves with you is rare. If you are chasing flavor clarity and a true connection with your barista, this is the place"
