What the Bible says about Oinos
(From Forerunner Commentary)
Not only did Jesus condone the proper use of wine, but He knew what the qualities of a good wine were, a fact confirmed in Luke 5:39: "And no one, having drunk old wine, immediately desires new; for he says, 'The old is better.'"
Some have argued that, at the Cana wedding, Jesus changed the water into unfermented grape juice, not wine. However, the Greek word translated "wine" throughout John 2:1-10 is oinos, which means "fermented wine."
