I doubt you could hear the call of such an effect over the roar of other confounders: Regular moderate wine consumption is a strong correlate of comfortable, non-suburban living, particularly in a post-MADD world. Generally speaking, drive less on a daily basis, walk more on a daily basis, have better cardiovascular health and less obesity, live longer. This is a significant EU/US delta. In the US wine is not the cheapest way to get drunk, nor is it as socially popular in disadvantaged minority groups. The health issues associated with poverty & healthcare/nutrition access are less significant in wine drinkers, and the lifestyle of those statistically drawn to wine as a beverage of choice is correlated with lower stress levels. These aren't new or novel observations, but when we're talking about very weak effects, even the uncertainty bounds on known confounders start to dominate.
