First of all, in the process of evolution, we humans sometimes need to eat a lot of fruits, but at that time there was no such good storage technology as ice cubes and refrigerators. Many fruits can't be well preserved and will ferment to a certain extent. Eating that kind of fruit at this time will inevitably lead to alcohol intake, and some people may ask why they eat this kind of fruit. As mentioned above, it is in the process of human evolution, not civilized society.
At the beginning, human evolution was incomplete and there was no ability to metabolize alcohol. There was a state of drunkenness at that time. However, in the process of gradual evolution, due to long-term intake of this fruit, the human body gradually evolved the ability to metabolize alcohol and preserved it. The history of alcohol is actually earlier than that of people. Before the birth of human beings, ripe fruits fell from trees, then rotted and fermented, and then melted into water, and they were born. Wine? And in the process of evolution, humans must have drunk this kind more than once? Alcoholic drinks?
Another point is that we ate a lot of these fruits in the process of evolution, which may lead to our genes' fascination with wine. Even if we don't eat fermented fruits and wheat now, we still have to make wine to meet our own needs. At the same time, due to the different regions where human beings were born, the wines brewed will be different, which has resulted in wine cultures all over the world, but the ingredients and tastes are different.
To sum up, wine culture appeared earlier than human beings, and it was only a matter of time before people discovered it. Coupled with different regions, different wine cultures have emerged all over the world.
