What is grain wine and how is it different from rice wine

Grain wine is an ancient traditional liquor in China, which is made from rice grain, with pure-bred small currant or traditional liquor medicine as the saccharifying and fermenting agent, saccharified by cultivated bacteria, fermented in a tank, and then distilled.

Rice wine is produced by boiling rice and then fermenting it with liquor medicine and then filtering it with heat.

The principle of making grain alcohol is similar to that of rice wine, except that one uses rice as the raw material and the other rice as the raw material.
