Wrong on both counts.
The fact that Jesus drank the 'fruit of the vine' does not preclude that he was drinking plain grape juice. Not every grape was fermented, even then.
With 3 1/2 years to complete His mission on earth I have a difficult time picturing Christ as imbibing many, if any, fermented beverages. If He did, He did. You don't really know either so knock off the snide remarks about bible reading. It's a moot point.
