Is there an unglazed pottery bowl better?

Unglazed ceramic bowls can be used to hold vinegar. The quality of this ceramic bowl is quite good.

If high-quality clay is selected as the raw material of the jar, the metal elements on the surface of the clay can also catalyze the oxidation and reduction of wine, accelerate the aging and achieve the effect of improving the quality of wine; Glazed jars have high output and more affordable prices. If there is no high-quality pottery jar, you can use a pottery jar with no glaze inside and glaze outside to ensure that the wine can contact the pottery surface, and the glaze outside will not be completely "sealed", and a small amount of air will also enter, resulting in "breathing".

Comparatively speaking, glazed jars made of fine mud are more suitable for storing wine than unglazed jars.
