Overview
Cedar barrels and two summers of natural fermentation shape this Ohsawa nama shoyu, brewed in Kamikawa, Japan, from organic soybeans, whole wheat, sea salt and spring water. It is left unpasteurized, so its natural enzymes remain.
A mellow, savory flavor that tastes less harshly salty than mass produced soy sauce makes it a finishing sauce worth tasting on its own. It is not soy-free or gluten-free, since it is brewed from soybeans and wheat.
Who it's for
Sushi nights, cold soba and simple tofu dishes show off its rounded flavor. People with soy or wheat allergies should not use it.
Pros and cons
- Long cedar barrel fermentation
- Unpasteurized with natural enzymes
- Organic ingredients only
- Mellow, savory flavor
- Contains soy and wheat
- Not suitable for gluten-free diets
- Flavor can fade if heated long
Performance notes
Slow fermentation in cedar breaks down soy and wheat proteins into rounded umami compounds, giving depth beyond plain saltiness. Because it is not pasteurized, the enzymes stay active, which suits raw uses like dipping and finishing. Long cooking dulls the delicate aroma, so add it near the end.
