Introduction saccharomyces cerevisiae is a species of yeast generally used in the beer and wine making process this type of fungi has been studied as a eukaryotic model organism and was the first eukaryotic genome to be completely sequenced1many proteins and pathways were discovered in humans by studying the homologs found in the yeast.
Even though yeast is found naturally on the surface of grapes, wine yeast is added to the crushed grape pulp to produce the type of fermentation required for quality wine production the important characteristic of yeasts is that they metabolise sugars to form alcohol without using oxygen. Control of fermentation temperature is a critically important factor in quality wine making the proper fermentation temperature is dependant on many factors, the most important of which is the style of wine to be produced. Fermentation and anaerobic respiration how cells extract energy from glucose without oxygen in yeast, the anaerobic reactions make alcohol, while in your muscles, they make lactic acid.
After fermentation, a deliberate management policy must be adopted, depending on wine style carefully controlled use of co 2 in the winery can optimise levels of oxygenation in the wine making process.
