Because rice vinegar is white, smells faint and fragrant, and has moderate acidity and sourness, Laba garlic soaked with rice vinegar not only has faint fragrance, but also uses more jadeite color. If you use old vinegar, it will lead to a little blackening of the pickled garlic. Don't use white vinegar either, because many white vinegars are solid white vinegars, which are blended. Although this vinegar is sour, it lacks fragrance.
