Unfermented wine?

While I am not a fan of controversy, and certainly do not want to use this blog to impose my personal theological convictions, occasionally I am exercised enough by what others are saying that I am willing to enter the lists. In this post I am tackling the misleading theme of unfermented wine. I am neither a NT Greek scholar nor an expert in ancient viticulture. However, by the grace of God I can read. The argument is that Jesus drank only unfermented ( non-alcoholic) wine, and that it is sinful for a genuine follower of Christ to have alcohol at any time. It is true that alcoholism is a scourge of any society, and has proven the ruin of many people. Numerous others have been battered by its destructiveness, and the Bible in both the Old and New Testaments strongly warns against drunkeness, e.g. Proverbs 23:29-35, Galatians 5:21, 1 Peter 4:3. 1 Corinthians 6:9-10 states that drunkards, among others, will not inherit the kingdom of God, thus putting to rest the idea that it is a disease for which people bear no personal responsibility.
Today, I am responding to those at the other extreme. Mentioning Jesus' first miracle at Cana ( John 2:1-11) when he turned approximately 150 gallons ( about 600 liters) of water into wine, or Paul's admonition to “No longer drink only water, but use a little wine for the sake of your stomach and your frequent ailments,” ( 1 Timothy 5:23) is circumvented by the phrase unfermented wine. The reality is that we have a phrase in English, grape juice, which describes this perfectly. There really is no such thing as unfermented wine. Wine has alcohol in it; grape juice does not. Until the advent of modern technology it wasn't possible to store grape juice for any length of time before it began to ferment. This is why the name of Thomas Welch, a Methodist, is associated with grape juice, because he invented a process of pasteurization to prevent fermentation ca 1869. NT Greek has three different words to describe wine, the most common of which is transliterated as “oinos.” It also has a word for grape juice, “trux” which is nowhere used in the NT. While these simple facts should be sufficient to close the debate, I am confident that attempts will be made to dismiss them.
For the record, I do not drink alcohol, and haven't since February 5th, 1973. However, I do not attempt to impose my practice on others or refuse to fellowship with those who do partake. I believe that “the kingdom of God is not a matter of eating and drinking but of righteousness, peace and joy in the Holy Spirit.” ( Romans 14:17) Because I do not wish to tempt or stumble others, ( Romans 14:21), I relinquish the freedom to drink in moderation that Christ gives us.
Now some will grant that believers may partake but that anyone in a leadership role is forbidden. One wonders why the qualifications in 1 Timothy 3:3 or Titus 1:7 that state that an elder must not be a drunkard are insufficient. Are we, like the Pharisees that Jesus rebukes in Matthew 15 and Mark 7, adding our own traditions to the commandments of God?
