Sufis hold very diverse views. Some are conservative and keep strictly to Quran while others believe that rigid rules are unnecessary and God can be pleased by doing what feels right and by respect of other people and generosity alone.
They may think that it is not necessary to interpret literally that Allah forbade alcoholic drinks. Maybe he just meant to advice against their excessive use or that overall, "true Islam" is hidden behind the words of Quran that some human still ultimately printed or wrote on a piece of paper.
Many Muslims however just don't care. I know many of them (who aren't even Sufis) who drink alcohol from time to time because they think that it can't be too important for Allah to refrain from drinking it. In contrast, none of my Christian friends follow every single rule that is in the Bible because they don't think that God is that precise with rules and that he understands and forgives those who sometimes break them.
And by the way, Turks, be they Muslim or not, have drank raki for centuries. It is a Turkish version (or basically the same as) of Greek ouzo, strong anise flavored alcoholic drink.
