The Umami Bros Land at Fortnum & Mason: A New Era for Japanese-Style Mayonnaise

We’re In… Fortnum & Mason, Piccadilly!

We’re proud to announce that The Umami Bros have officially secured a spot as one of the 10 winners of Fortnum & Makers Open Call; a nationwide search for the UK’s most exciting emerging food and drink brands.

Out of over 200 entries, our MSG-free, gluten-free, umami-rich Japanese-style mayonnaise stood out and earned its place in the legendary Fortnum & Mason store. What started as a lockdown idea has grown into an award-winning Japanese mayo that’s now part of the culinary conversation at one of Britain’s most iconic institutions.

| Fortnum & Mason calls our product “…possibly the best mayo you’ll ever taste.” – https://www.fortnumandmason.com/fortnum-and-makers

Starting 14th August, you’ll find us on the Ground Floor at Fortnum’s Piccadilly. Come say hi, taste the magic and meet the Bros behind the bottles.

Why Our Japanese-Style Mayonnaise Is Different

We launched The Umami Bros with one mission: to create a sauce that hits different. Inspired by global cuisine but rooted in premium, clean ingredients, our mayonnaise celebrates umami, the fifth taste, and elevates everything from sushi to sandwiches.

Unlike traditional brands, our mayo is:

MSG-free
Gluten-free
Made with egg yolks, not whole eggs
Infused with umami-forward flavours like yuzu

Whether you’re a home cook or a professional chef, our Japanese-style mayo is designed to bring depth, richness and enhance to your dishes.
