Why is it important that barley contains sugar?

Barley contains sugars, which are essential for the fermentation process in brewing and distilling, as they provide the necessary carbohydrates for yeast to convert into alcohol. Additionally, the sugars in barley contribute to the flavor, color, and mouthfeel of beers and spirits. Furthermore, sugar content is crucial for the growth and development of the plant itself, aiding in its energy storage and overall health.
