"Fruity esters" may be formed if the yeast undergoes temperatures near 21 °C (70 °F), or if the fermentation temperature of the beverage fluctuates during the process. Lager yeast normally ferments at a temperature of approximately 5 °C (41 °F) or 278 k, where Saccharomyces cerevisiae becomes dormant. A variant yeast known as Saccharomyces ...
During fermentation, there are several factors that winemakers take into consideration, with the most influential to ethanol production being sugar content in the must, the yeast strain used, and the fermentation temperature. [15] The biochemical process of fermentation itself creates a lot of residual heat which can take the must out of the ...
[citation needed] Typically, the wine is heated to 185 °F (85 °C) for a minute, then cooled to 122 °F (50 °C), at which temperature it remains for up to three days, killing all yeast and bacteria. It may then be allowed to cool, or be bottled "hot" and cooled by water sprays.
It may be performed at bulk-fermentation temperatures, [29] or temperatures up to about 95–100 °F (35–38 °C), and with 83–88% relative humidity. [21] Yeast thrives within the temperature range of 70–95 °F (21–35 °C), [7] and within that range, warmer temperatures result in faster baker's yeast fermentation times. The proofing ...
During this time, temperatures should be kept at optimum temperature for the particular yeast strain being used. For ale this temperature is usually 18–24 °C (64–75 °F); [ 61 ] [ 62 ] [ 63 ] for lager it is usually much colder, around 10 °C (50 °F).

Saccharomyces cerevisiae, the yeast commonly used as baker's yeast. Gradation marks are 1 μm apart.. Baker yeast is the common name for the strains of yeast commonly used in baking bread and other bakery products, serving as a leavening agent which causes the bread to rise (expand and become lighter and softer) by converting the fermentable sugars present in the dough into carbon dioxide and ...
Fermentation of sugars by yeast is the oldest and largest application of this technology. Many types of yeasts are used for making many foods: baker's yeast in bread production, brewer's yeast in beer fermentation, and yeast in wine fermentation and for xylitol production. [57] So-called red rice yeast is actually a mold, Monascus purpureus.
