Most sources agree on a range between 20 and 30 celsius. 20C is 68F, 25C is 77F and 30C is 86F. Some claim that the lower end of the scale is better, some claim the upper to be better. Playing it safe would place you in the middle, or 25C (77F).
Temps lower than 20C will slow the yeast's ability to produce alcohol, and higher temps, such as 35C (95F) will kill the yeast entirely.

Alcoholic Fermentation.
Temperature affects yeast respiration and fermentation because it influences the rate of enzyme activity. Yeast activity increases with higher temperature, up to a certain point, beyond which it decreases due to denaturation of enzymes. Optimal temperature ranges between 25-30°C for most yeast strains.
If the temperature at the start of fermentation is too high, it can cause the yeast to produce off-flavors and aromas in the final product. Additionally, high temperatures can lead to uncontrolled fermentation, resulting in a stuck or stalled fermentation process. It's essential to maintain the correct fermentation temperature for optimal yeast activity and flavor development.
it undergoes fermentation
Organisms such as yeast, bacteria, and some fungi use alcoholic fermentation to convert sugars into ethanol and carbon dioxide in anaerobic conditions. This process is commonly used in the production of alcoholic beverages and baking.
Yeast is an organism in which alcoholic fermentation takes place. It converts sugars into alcohol and carbon dioxide in the absence of oxygen during fermentation.
alcohol fermentation -- the ethanol (alcohol) and carbon dioxide are produced by the yeast.
yeast
Yeast fermentation is affected by temperature as a result of the various different standards of temperatures that the yeasts are exposed to. If the yeasts are exposed to their optimum temperature(approximately 66.667 degrees Celsius), then this would yield the most amount of fermentation. However, the process by which fermentation occurs in the first place is by respiration, which obviously includes enzymes. Thus, if yeast cells become denatured, as a result of a too high temperature, which causes the yeast cells enzymes to be denatured, then the yeast would not ferment to the best of their ability, hence causing a decrease in the rate of fermentation. Likewise, if the yeast cells are exposed to low temperatures, then the yeast cells would be inhibited, and so they would also not work. However, this can be fixed unlike the prior case. When temperatures become optimum again, the yeast would ferment as usual again.
