Why did Jesus convert water to wine at the wedding of Cana, if the Bible speaks against alcohol?

The wine which the Lord converted from water was not fermented, it was refreshing grape juice, and for this reason, the master of the house commented, “Every man at the beginning sets out the good wine, and when men have well drunk, then that which is inferior, but you have kept the best until now� (John 2:10).
