Great Taste 3 Star Award Winner for 2026!

Experience the authentic taste of Japan with Sanbaizu (Sambaizu) seasoned rice vinegar from Marusho, aged and fermented in 100-year-old cedar wood casks, each uniquely named after a sumo champion. 

Crafted using hand-controlled fermentation and pure water from the Kumano mountains, this vinegar delivers a quintessentially Japanese flavour rich in umami, prized by top chefs for generations.

Infused with high-quality natural ingredients, kombu seaweed, bonito flakes, mirin, amazake, shiitake mushrooms and a touch of sugar, Sanbaizu is delicately balanced, offering a complex, savoury, and subtly sweet profile.

This premium rice vinegar is perfect for creating authentic Japanese dishes, enhancing sauces, and adding depth to everyday cooking.

Here's what some of the Great Taste Judges had to say about our Sanbaizu and why they awarded it 3 stars!

"This is a lovely deep amber colour and has a very smooth mouthfeel. We really enjoyed the complexity of this vinegar, which is sweet, fermented, very slightly fishy in a good way - it would be so versatile in the kitchen. And we can actually just drink it. We think this is a remarkable and delicious product."

"This is as good as rice vinegar gets. Sweet, umami, and ultimately drinkable. We feel the acidity is absolutely perfect, with delicate saline notes to provide the backbone. This has so many uses and would enhance many culinary dishes. It is exquisite."

"This attractive golden brown vinegar has a savoury umami aroma that delivers as promised on the palate. This is rounded, deep, lingering and lacking in harshness - a delightful store cupboard ingredient that we found drinkable in its own right."

"Crystal clear and gleaming with a mahogany colour, the vinegar delivers a deeply appealing salty richness with surprising rounded sweetness, almost broth-like in nature. Beautifully smooth, with lip-smacking richness and a flavour journey that evolves and persists seductively. Truly a delight and the judges could visualise this as sensational with Wagyu beef and a pak choi salad, for example."
