MY Fermentation is a coffee shop on a quiet alley of Rue Saint-Bon in Paris that centers on fermented ingredients, reinterpreting Korean and Japanese food with French flavors. The menu includes kimchi grilled cheese, a miso signature latte, tamari Basque cheesecake, and amazake brownie. Kombutcha-making workshops are available, and the owner recommends menu items and explains them one by one. The omelette contains miso butter.
