In a large bowl, mix together the wine, olive oil, sugar and baking powder.  Mix in 3½ cups flour.  If the dough is still wet, add in the more flour until a soft dough forms.  Transfer the dough to a lightly floured work surface.  Knead until the dough is smooth and no longer sticks to the surface. Cover the bowl and allow to rest for 30 minutes.

Preheat the oven to 350 degrees Fahrenheit.

Form the cookies: Cover a baking sheet with parchment paper. Pinch off a walnut sized piece of dough and roll out to form a log approximately 4 inches in length. Bring together and overlap the two ends of the log and pinch to form a ring.  Pour some sugar onto a small plate.  Dip one side of the cookie only in the sugar and place, sugar side up, on the baking sheet.  Cook until lightly browned, 20-15 minutes.  Let cool and enjoy!
