## Customer Reviews

### ⭐⭐⭐⭐⭐ Rich and complex flavour, excellent value for money
*by M***. on 13 September 2022*

It is claimed to be made with the traditional pre-industrialization method, fermented in "kioke" wooden barrels and not heat treated, in the manner shown by some youtube videos (search "Murashima soy sauce"). The flavour does feel richer and more complex than any other popular brand I've ever tried. Considering the extremely demanding process required to produce this type of sauce (apparently only 1% of total soy sauce production in Japan is made this way), the value for money is excellent.

### ⭐⭐⭐⭐⭐ You have not tasted soy sauce as good as this
*by L***7 on 13 June 2022*

Costs slightly more than say Kikkoman but you are paying that bit more to receive a far superior sauce. Sauce made in the old way using decades old wooden barrels and giving it extra time to develop and then pressed, simply fantastic. Try with sushi and you will not regret it. it tastes a bit sweeter, less salty and very slightyly fermented taste than average factory stuff.

### ⭐⭐⭐⭐⭐ Lush
*by N***. on 24 October 2021*

Excellent Soy Sauce, wonderful flavour and not too salty. Not cheap, but you get what you pay for. I had one made by Clearspring before and it was good, but not as good as this one.
