about us

We love the simplicity, quality, and taste of food that originates from Japan and is made using Koji - a noble fungus that as a fermentation tool can transform even the most ordinary ingredients into literal taste miracles.

Inspired by this ancient tradition, we make miso pastes, miso soups, tamari, shiokoji, vinegars, and other great things in the Czech Republic from local ingredients to fit in with European cuisine. Both at home and in professional gastronomy.

Milan, Honza, and a team of great people around us.

It all started with studying traditional Chinese medicine, burning out at management positions, and meeting Václav, who was making miso at home. With him, we started a joint project at the end of 2019 with the goal of supplying excellent ingredients to the best restaurants in our country.

The spring of 2020 redirected our efforts, basically out of necessity, to end customers, the e-shop, and the concept of preprepared miso soups. In addition Václav left us unexpectedly and later sold his share. Even though we didn't initially imagine it this way, it was ultimately the best thing that could have happened. We built a team of amazing people, launched new products, got into the awareness of the wider public, and almost couldn't keep up with demand.

In the autumn of 2021, we moved into our own premises and built a new facility in the beautiful surroundings of the Křivoklátsko region so that we could expand our production further. Both in terms of volumes as well as product range, because the most creative experiments and the alchemy of new flavors are the foundation we build on at Kojibakers.

In 2022, restaurants led by Michelin-starred Field returned and more opportunities opened up, including export ones. All of this has meant a significant professionalization of production, including international certifications, which we have managed to achieve while maintaining our core values and approach.

We still enjoy it. More and more, actually.

We still surround ourselves with nice people. Maybe even better ones.

And we still haven't compromised on the quality of our ingredients or our products. Quite the opposite.
