Is Fre Wine Really Alcohol-free?


Recently, the word “Fre wine” is under heated discussion. For years, Drunk drivers have made countless accidents and I am so glad that the fre wine comes out to help. Various methods are used. As far as I know, all start with standard wine and none remove absolutely all the alcohol. Reverse osmosis (membrane) and vacuum distillation (boiling the alcohol off in an artificial vacuum; the vacuum lowers the boiling point) are the most common methods in Europe. Spinning cone columns (a complex and expensive combination of vacuum and centrifuge) are popular in the US and increasingly elsewhere, though it is believed that they are used mainly to lower the strength of high alcohol wines (from, say, 16% to 14%), not to produce nearly alcohol-free wines.
But I Doubt so much whether the drinkers feel the same as drinking the alcohol and I wander if they would like to drink the free wine. Anyway, I am so happy

that people come to realize the dangers of alcohol and attempt to remove it.
