At hartmud Studio we are committed to serve the specialty coffee avant-garde, and we love to realize collaborations with professional baristas and coffee entrepreneurs who are really redefining the experience of specialty.

We value the true spirit of entrepreneurial cooperation: mutual benevolence, the resolve to achieve perfection together and the knowledge that where my competence ends is where my partners competence starts, and vice versa.

Since 2017 the reputation for our ultra hard stoneware cups for specialty coffee puts our wares in selected roasteries and coffee shops, but we‘re still lucky enough to remain a niche brand, known only to connoisseurs and hardcore baristas. We don’t expect to have our cups on display at every coffee corner. We don’t have the production capacity for that neither.

So if you are at the forefront of specialty coffee looking for the right hard cups, don’t hesitate to contact us.
