First the grapes must be crushed removing most of the stems. A little stem is good as it adds tannin to the wine. This grape crusher above crushes the grapes and automatically removes most of the large stems. It is placed over the vessel that will be used for fermentation.
This is 20 cases of grapes crushed. At this point the wine is left to spontaneously ferment. Natural yeast that lives on the skins will consume the sugar and create alchohol. This usually begins in a day or 2 and lasts about 5 days or so. Red wine fermentation occurs with all skins in contact with the grape juice. From the skins are derived the color, tannin and characteristic aroma of red wine.

After pressing the wine is put into some sort of bulk aging vessel. This is a 54L glass demijohn typical of small scale wine making. Fermentation will complete in this vessel expelling any remaining oxygen picked up during pressing. From this point on great care must be taken to exclude oxygen from the ageing wine. This means containers must be filled almost to the top and splashing of the wine during transfers must be avoided.
The wine must now age, mature and settle. This is best done by patience. Wine should not be rushed. Between 1 and several months the wine will be transferred off any sediment that has collected in the fermenter. It must be transferred again after a few months. And possibly again. During each transfer you will be leaving behind grape matter and dead yeast cells further clarifying the wine. As mentioned above great care must be taken to exclude oxygen. Fill your ageing vessels to the top. If there's extra drink it and observe how the wine evolves over time.
