The Umami Bros Japanese Style Mayo is a really great product with a fantastic flavour and texture. Would certainly buy this and other products from them again!

Written by the company

Made in Lockdown. Built on Flavour. We’re the Umami Bros – three friends who started experimenting with flavour during the chaos of lockdown 2020. What began as a home kitchen obsession quickly became a mission: to craft a Japanese-style mayo with a British heart. Finding the right ingredients wasn’t easy. Sourcing during COVID meant delays, dead ends, and a lot of trial and error. But after months of testing and tweaking, we landed on a recipe we loved – rich, smooth, and bursting with umami. Born from craving, built with care – this is mayo made for flavour fans, by flavour fans. But don't just take our word for it; our mayonnaise has been awarded stars with the Great Taste Award for the last four years. Our product is silky, tangy and packed with umami. This Japanese-style mayonnaise is made in the UK using only the good stuff — 100% egg yolk, a carefully balanced blend of vinegars and cold-pressed British rapeseed oil. The result is a rich, velvety mayo with depth and character; perfect for drizzling, dipping or dolloping. We'd love to hear from you!

I was given the opportunity to try the Japanese Style Mayo

I was given the opportunity to try the Umami Bros Japanese style mayo. The product was delivered swiftly and packaged well.

Our family already has some big consumers of mainstream mayo, whilst myself I’m not a big mayo fan.

However upon trying this product it was an instant hit for all of us. A mayo with a hit of added depth of flavour and creaminess made it delicious and a new fav in the house.

Thumbs up Umami Bros

This is a rich and subtle mayonnaise

This is a rich and subtle mayonnaise. The flavour enhances the food it goes with rather than dominating it. The richness adds a lovely texture to the food and finally it leaves a satisfying taste on the palette.

I am thoroughly enjoying having it with a variety of foods from chips through to sandwiches.it has certainly helped with the turkey leftovers this year.

Quality product with great customer service

After seeing a post on LinkedIn about some of their Japanese Style Mayonnaise reaching end of line, the Umami Bros generously sent me out two bottles absolutely free. Loved the openness and commitment to try and prevent wastage!

Super friendly service, quick delivery and a delicious mayo to top it off! Would highly recommend.

Fantastic taste and consistency

Fantastic taste and consistency. Adds a whole new dimension to meals. I have so far used it on stir fry chicken and noodles, on a meat feast pizza, and on sausage and chips. Delicious.

Absolutely delicious mayonnaise

Absolutely delicious mayonnaise – rich, unique, and bursting with flavour! It has such a distinctive taste that elevates anything you pair it with. We’ve enjoyed it with fish, mixed into potatoes, and even drizzled over pizza, and every time it’s been outstanding. A real game-changer for meals!
