Actually, it could all make sense. I thought it was this thread that someone pointed out alcohol's vasodilatory properties, but I guess not. Anyway, that is true that alcohol can really dilate blood vessels if "done right".
Check out, for example, this study where in health and moderately health subjects, alcohol's ability to expand arteries was as strong as many drugs:
Br Med J, 1967 April 29, 2(5547): 274–277, "Vasodilator properties of alcohol"http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1841894/?page=1
However, this study makes a worrisome comment: "Epidemiological12 and experimental13,14 studies have demonstrated that the ingestion of alcohol is associated with an immediate decreasing of blood pressure (an effect typical of vasodilators), which is followed by a rebounding elevation of blood pressure." (Hypertension, 2005; 45: 851-852"Vascular Effects of Alcoholic Beverages Is It Only Alcohol That Matters?")http://hyper.ahajournals.org/content/45/5/851.full
Notice that in the above study, they're not totally sure how it works, echoing this 1990 study's commentary:http://jap.physiology.org/content/68/2/731.abstract
However, this argues that ethanol can be another tool in your arsenal if done correctly, i.e. it may work on a little different pathway than some of the supplements and foods. As you know from my site, though, alcohol makes me a little nervous because of the pro-cancer and anti-testosterone connections.
