Interesting.
It is clear that the Torah does not encourage people to become Nazirs. As several of the Rabbis in the Naso thread I posted have related that the Torah itself requires a sin offering from the Nazir at the end of their vows. This is because Hashem doesn't require us to be ascetic, giving up the pleasurable things in life.
Wine is used to sanctify Hashems name, as we always do Kiddush at every Shabbat, Yom Tov, and other joyous occasions.
