I'm pretty sure that in historic Muslim states, people drank a lot more alcohol than we might think despite Islam's prohibitions. I'm pretty sure the existence of "Shiraz" for one of the most important wine varietals nowadays implies that Islam didn't kill Persian wine production. It seems akin to the Christians nowadays who oppose drinking alcohol (and drink non-alcoholic grape juice for communion) but believe Jesus drank wine (and of course turned water into wine--actual wine, not the grape juice some Christian groups believe, and these are all evangelical groups I'm describing) because that was the only safe drink available in his day, it was just far less ABV than wine is nowadays. Not to mention the many, many examples of Islamic leaders being known for alcohol consumption--Ottoman ruler Selim II aka "Selim the Sot" is only one example.
