Finland's National Centre for Technology research recently announced that the center has developed a wider range of suitable temperature yeast strains, in particular its low temperature resistance to wine and cider, reduce the risk of contamination in the winemaking processthese new yeast strains are produced by a hybrid of wine yeast and cold-resistant wild yeast and can withstand temperatures between 10 and 37 degrees Celsius, which is larger than the 20 to 30 degrees Celsius typically used for wine and cider fermentationresearchers say the new yeast strain has several advantagesFirst, it allows the wine-making process to take place at a lower temperature, which helps reduce the risk of contamination during the winemaking processOn the other hand, its relative high temperature resistance is conducive to the mass production of active dry yeastIn addition, as the tolerance temperature range is expanded, people can fine-tune the aroma of the cider by changing the fermentation temperaturepreviously, researchers have successfully used this hybrid technique to grow yeast strains that can be used to brew beerBecause yeast used in foods such as baked bread needs to survive in frozen dough for a long time, researchers are also evaluating whether the hybrid ization technique can produce yeast strains for the baking industry
