Vulcans are immune to the dubious benefits of alcohol, and Vulcan port is typically only consumed in rituals. I am uncertain of alcohol's effects on half-Vulcan, half-Human hybrids, but I should note that Vulcan traits are typically dominant, and my physiology is predominantly Vulcan. However, chocolate has been known to produce effects in Vulcans that resemble the effects of alcohol and other intoxicants in humans.
