Yeah..... that is the sorry state of news these days at CNN. It's total tabloid and puppy pictures these days at CNN. They also use vague titles for articles to increase click through rates - since you can't tell if you want to read the story without clicking through first and seeing what the hell they are talking about.
I have a really strong category-killer type alcohol domain with Parked and nothing beats New Years Eve. The cycle repeats every year. It looks like traffic is up 30% for the July 4th weekend. However, on New Years Eve traffic goes up about 600%. It's a hard alcohol domain and not beer/wine related.
Unless beer, wine, etc.... is that much bigger on July 4th compared to New Years Eve, then I'm guessing that New Years Eve wins hands down as the day with the most alcohol consumption.
I imagine beer is consumed more on July 4th with all the BBQ's and such. It would be interesting to know the breakdown on different holidays regarding what is consumed.
