Any definition you can find of the word "wine" also includes the word "alcohol." This includes wines that have no alcohol, which are occasionally called alcohol-free.
However, the fact that we define normal wine as having alcohol kind of puts the phrase "alcohol-free wine" into a strange category, almost the way jumbo shrimp is an oxymoron.
From a scientific perspective, wine is the result of any fruit that's fermented, either accidentally or by design, and in which the fruits' sugars (such as fructose, glucose or sucrose) are converted into ethanol and carbon dioxide (CO2).
