Processing aids for wine production
Processing aids for wine production (yeast, lactic acid bacteria, fermentation aids) End of the 19 Century, Pasteur pointed out the importance of controlling alcohol fermentation with a well-chosen yeast. Many wineries now make wine by using selected yeasts rather than grape-attached yeasts. Also, selected lactic acid bacteria are used in malolactic fermentation to bring roundness and complexity to the wine.
Wine is made by converting the sugar contained in grapes to alcohol by yeast. In recent years, it has become common to add good yeast for healthy fermentation and stabilization of liquor quality. The characteristics of the finished wine can be changed from the yeast used, and you can make thiol style wine and ester style wine. Also, hybrid yeasts and yeast blends are used in wine making to add depth and complexity to the wine’s flavor.

AlchemyIII & AlchemyIV for red wine
Alchemy III and Alchemy IV are blended products of hybrid yeasts that are mated with spores isolated from different yeasts to compensate for the disadvantages of the parent strains and extend their strengths.
The graph on the left shows that Alchemy III is unique to the hexanoic acid ester, and Alchemy IV is unique to the phenol ethanol, and both produce low isobutyl methoxypyrazine, which causes a green vegetables odor.
Lactic acid bacteria for malolactic fermentation
Yeast and lactic acid bacteria can be added simultaneously, and alcohol fermentation and malolactic fermentation can be performed simultaneously. (= Co-inoculation)
In the past, malolactic fermentation was carried out after alcohol fermentation but with the simultaneous addition and fermentation, the abundant nutrients, moderate fermentation temperature, less alcohol and less medium-chain fatty acids provide a better growth condition for lactic acid bacteria. In addition, simultaneous fermentation will result in a fruitier floral wine, improving color and color stability.
