Kur'an does not approve alcohol consumption at all. I can also can not tell if it is forbidden in the book. Even though it is not forbidden in the book, Muhammed may have done it, which counts as a forbid.

In Ramadan, alcohol consumption is not..hmmm..well favored. And people mostly apply that..It's a time when you rip earthly pleasures off yourself; that's why -any other things you can "a pleasure" added (considering your biological limits, of course...ahem..)
