An experiment to demonstrate the effect of temperature on fermentation by yeast The purpose of this laboratory is to observe how temperature affects the metabolism of Grape juice by visibly noting the volume changes of identical food mixes containing yeast at different temperatures. Background Information If yeast is added to a liquid containing sugar and other nutrients‚ kept at an appropriate temperature (and deprived of oxygen)‚ it will turn the sugars into ethanol (alcohol) and carbon
