What drinks did Guanzhong people drink in the pre-Qin period?

For reference:

The main drinks in the pre-Qin period are: water, pulp, wine, plum, Iraq and Huo.

Water. From ancient times to the pre-Qin period, the ancients had deep feelings for water. In ancient times, the five elements were emphasized. Qin was still black, and black was the virtue of water, so the color of water was black, which was called "Xuan". Therefore, the ancients in pre-Qin called water "Xuan wine" after the appearance of wine. The purpose of using clear water as a sacrifice is to recall that our ancestors drank water. Therefore, Tianzi's best drink is water.

Flesh. Many people think it's rice soup, but some people think it's sour soup made by putting cooked vegetable leaves into rice soup (or noodle soup) and adding yeast. Now Guanzhong is still making it, called oar water. Most people drink pulp, so they don't have to use it when offering sacrifices, otherwise it looks tasteless and disrespectful to their ancestors.

Wine grains (plum). Wine refers to sake brewed by millet. Ku refers to sweet wine brewed with rice.

Easy (easy). Slurry is a soup without rice, while Naan is a soup with rice or other grains.

Aunt Huo drinks bean leaf soup.

Tea. There are many theories about the origin of tea. It is generally believed that there was tea in the Western Zhou Dynasty, when tea was offered by southern tribes or countries. Of course, drinking is also a matter for a few nobles, and the people are not blessed.
