Alcohol? You're kiddin' me... right!?
At least at first glance it certainly looks as if you could hardly find better news for all the partying muscle heads out there, than the soon-to-be-published paper by Jakob L. Vingren, David W. Hill, Harsh Buddhadev, and Anthony Duplanty from the Department of Kinesiology, Health Promotion and Recreation at the University of North Texas (Vingren. 2013). After all, the four Texans discovered that the ingestion of booze instead (and probably also along with) your protein shake after your workout will prolong and amplify the "anabolic state" you're in once you leave the gym fo a couple of hours. Bullshit? No, it's not April the first, yet.
The participants were 8 healthy previouly resistant trained men (21-34 years; 87.7kg, 177 cm, 15.1 % body fat) who performed 6 sets of 10 repetitions of Smith machine squats starting at 80% of 1RM and 2 min of rest between sets (assisted forced reps, when necessary) after an appropriate warm-up:

Sound easy right? But does it help at all?
You probably did not start boozing already, right? Otherwise you would not pose smart questions like the one in the above subheading. Obviously, the researchers asked themselves a very similar question: Can this poison really be ergogenic? Unfortunately, their answer does not really go beyond serving us the same old paradigm of the "anabolic milieu", the validity of which is more than questionable (suggested read: "Does the "PWO Elevation of Testosterone Influence Muscle Growth?"):
In the researchers defense, it does yet have to be said that they do not simply ignore the fact that the significance of workout induced changes in the "anabolic milieu" in terms of immediate skeletal muscle growth may have been overrated.
"Although the T:C [ratio between testosterone and cortisol] is a crude measure, it response shows that the elevated in testosterone in the latter stages of recovery following ethanol ingestion is not associated with a corresponding elevation in cortisol, a hormone with catabolic and anti-anabolic physiological effects. The results for the T:C ratio suggest that a more anabolic milieu exists during the latter stages of recovery from resistance exercise following ethanol ingestion." (Vingren. 2013)
Strength, cardio or both for the optimal T:C ratio? (learn the answer)
Now, while we do not have any studies on the "the effect of post-exercise ethanol ingestion on protein accretion" (Vingren, 2013), we do have studies showing that the ingestion of alcohol in general appears to hamper the recovery from resistance training (Barnes 2010; Barnes 2012) and increases the suppressive effect of exhausting endurance exercise on testosterone production (Heikkonen. 1996). The logical conclusion, Vingren et al. draw is thus that it "remains unclear" how the ethanol induced maintenance of high free and total testosterone levels in the hours after a workout would affect the muscular adaptation processes and their downstream effects on muscle size and strength in response to resistance exercise.
Bottom line: Personally I don't believe that 1.5 pints of red wine make the ideal post workout drink, not just because they are lacking protein, but rather in view of the previous research from Barnes and Heikkonen which may not disprove the possibility that 1.06g of ethanol after a workout could potentially exert "anabolic" effects that will eventually manifest in greater gains in muscle size or strength, but should suffice to rate an already highly questionable hypothesis "very unlikely".

Overall the study at hand is thus nice for some intellectual masturbation, but should not serve as an excuse for regular alcohol consumption. Physical culture and booze were, are and will always remain incommensurable.
