This award-winning Oat Shoyu is produced in the fermentation house by our sister company, Slow Sauce. Complex, savoury, and packed with umami, this shoyu is carefully barrel-aged in oak casks for 3 months, blending Scottish oats with Carlin fox peas for a long umami finish. Use it generously in stir-fries, dressings, or drizzle over steamed vegetables or rice to unlock layers of deep flavour.
Shoyu is the Japanese name for soy sauce, typically made from fermented soybeans and wheat. We use the word because we use a shoyu fermentation protocol but use Scottish oats and Carlin peas instead.
Here are some of the judges comments from 2026 Great Taste Awards, where Slow Sauce’s Oat Shoyu was awarded 3-stars, the highest accolade:
“A shot of pure umami followed by bright, refreshing middle and top notes. A well balanced and interesting take on shoyu and one which we felt would be extremely versatile.”
“Packed with umami notes and the slight viscosity coats the mouth nicely.”
Ingredients: Scottish oats (50%), organic Carlin fox peas, sea salt, koji culture.
Allergen Info: Free from all major allergens. Gluten-free, soy-free, vegan.
Shelf Life: Store in a cool dry place then keep refrigerated and use within 6 months after opening. Shelf stable for 12 months after production.
