Okay, you know that grapes grow on vines and that they are picked at the peak of ripeness.
But what happen next?
The grapes along with the vines and some leaves are crushed and put in these big vats and sit for several days.
The stems, leaves and skins float to the top, but to keep the juices floating. The mix is stirred once or twice a day. Then after several days, they are move depending on if they are white or red grapes.
If they are red then they are put in this machine that separates off the leaves and steams. The skins are used in red wine to add color.
