What does Japanese soy sauce taste like?
Japanese soy sauce has a rounded, complex flavour with a combination of salty, slightly sweet and umami-rich notes. Natural fermentation creates subtle aromas that add depth to dishes without overpowering other ingredients.
What makes Yamasa soy sauce special?

How should I store soy sauce?
Unopened soy sauce can be stored at room temperature. Once opened, it is advisable to keep the bottle in the fridge. This helps preserve the aroma for longer and ensures the sauce retains its characteristic flavour.
