Yeast has a certain influence on the wine style. Environmental yeast is a semi carbon dioxide soaking method, and it is a kind of yeast in the process of alcohol fermentation. Environmental yeast strains exist in the frost of grape fruit and wineries, and are also known as natural yeast. Yeast can be used to add complex flavors to wine, but it is not controllable. There are also some differences in the batch of grapes. The yeast is not suitable for large-scale brewing. In addition, the yeast strains cultured by artificial culture can be selected for alcohol fermentation. Artificial yeast is a relatively stable yeast, which is selected by human, which can make wine attractive. However, for some winemakers, yeast limits the potential complexity of wine. I Believe.

② Temperature control and selection of fermentation container
The fermentation of wine produces heat. If the temperature is not controlled, the continuous rise of temperature will have a negative effect on the flavor of the finished wine. The winemaker can select a fermentation container with temperature control function to control the temperature of each stage of fermentation process. For red wine, various methods of controlling bottle cap during fermentation also affect heat dissipation. Although oak barrels can be used as fermentation containers, most winemakers do not use them to ferment wine because of their poor control of fermentation temperature.
