Glucose, along with fructose, is one of the primary sugars found in wine grapes. In wine, glucose tastes less sweet than fructose. It is a six-carbon sugar molecule derived from the breakdown of sucrose. At the beginning of the ripening stage there is usually more glucose than fructose present in the grape (as much as five times more) but the rapid development of fructose shifts the ratio to where at harvest there are generally equal amounts.

Wine in religious communities of the Middle East drinks such as "tilā’" and "naqir" as inebriating and thus forbade the pressing of grapes and the drinking of pressed grape juice.
