Complex, savoury, and packed with umami - this oat shoyu is carefully barrel-aged in oak casks for 3 months, blending Scottish oats with Carlin fox peas for a long umami finish. Slow Sauce ferment slowly, seasonally, and seriously. No short-cuts. No imported soy. Just well-grown ingredients, wild weather, barrels, time, and care.

Scottish miso, slowly made.

Slow Sauce is a fermentation project that began rooted in tradition, adapted to place. We make small-batch miso and shoyu using Scottish-grown gluten free oats and British peas, aged in oak barrels in the hills of Aberdeenshire.

Founded by fermentation obsessives Robin Sherriff and Jonathan Hope, Slow Sauce is part kitchen experiment, part agricultural rethink. They take the classic Japanese method of koji fermentation and reimagine it with the ingredients that they have here - creating something new that’s still deeply respectful of where it came from.

It’s miso, but not as you know it. It’s sweet, savoury, punchy stuff. Slather it on toast. Stir it through porridge. Sip it hot in the morning. Dress your salad. Glaze your veg.

  • Use generously in stir-fries, dressings, or drizzle over steamed vegetables or rice to unlock layers of deep flavour.
