Smart storage

Over time, the color of soy sauce gets stronger and its flavor fades. Therefore, it should be stored with care, keeping it out of direct sunlight and as cool as possible. Before it is opened, soy sauce is basically not prone to spoiling, even in long storage. Nevertheless, it is best to consume it before long, to enjoy its proper flavor. After it is opened, it begins a process of oxidation due to contact with the air, so it must be kept closed and stored in a cool, dark place. Such storage prevents the growth of yeast, but when keeping soy sauce at home, it is best to store it in a refrigerator. Another way to maintain the quality of soy sauce is to decant it from a container in the refrigerator into a small container, taking only an amount that will be finished quickly. Ideally, observe these precautions and finish the bottle within around one month.
