Welcome to HARTMUD studio
Founded in 2017 as an entrepreneurial collab of traditional pottery techniques, cutting edge product design and open source coffee community, hartmud Studio is manufacturing rare hard German stoneware with a focus on specialty coffee.
Baristas swear by hartmud when crisp aesthetics, proverbial robustness and superior thermics are key, and the studio humbly tries to provide the worlds heaviest, toughest stoneware coffee cups.
Due to small production numbers and high demand availability of hartmud is limited. We manufacture and sell our wares in batches and launch approximately one new drop per month in this online shop.
The restock or release dates are shown in the shop header and announced via instagram.
Visit the blog for in depth knowledge on our work standard, our design philosophy and all product updates.
