Terroir
Japanese: テロワール
French for 'land,' denoting the totality of climate, soil, topography, and human factors affecting a product. Known from wine, it applies to all fermented foods.
Terroir originated in wine but is an essential concept for all fermented foods. A miso brewery's unique flavor exists because its water, climate, resident microbes, and maker's craft form an inseparable whole. Same ingredients, same recipe—change the place and the flavor changes. Terroir is a single word for the fact that some things can only be made in one place. In a globalizing world, the concept of terroir can serve as an intellectual tool for protecting the uniqueness of local food. Recently, terroir-conscious product development is advancing in sake and miso. Even the same soybean variety yields different miso from different regions. As science increasingly confirms this, terroir is becoming a concept that speaks to fermented food's essence, beyond mere marketing.
