I don't believe it specifically states that he drank it.
It was his brother's wedding party. They ran out of wine. Jesus turned the water into wine. If not to drink it, what reason would he turn water into wine?
I'm sure the water was turned into wine for the purpose of drinking it, it just doesn't state that He drank it at the time.
I also believe He did drink wine at times such as The Last Supper.
I was just nitpicking, I guess it's my nature.
