it's hard to describe, but i don't like the way soy sauce tastes after the bottle has been open for a while. i have been buying large bottles of it but it seems like it doesn't take long before it gets that funny smell and taste. recenty, i bought a new one and kept it in the fridge instead of pantry, but the same thing happened. i don't think it has gone bad, but it's very different... does anyone know what i mean? thanks.
