In a large bowl, stir together the flour, sugar, baking powder and salt.
Make a well in the centre of the flour and add the white wine and vegetable oil.
Using a wooden spoon, stir the ingredients together until a soft dough is formed.
Turn out the dough onto a lightly floured surface and kneed gently until smooth.
Let rest for 15-20 minutes.
Preheat oven to 350F.
Divide the dough into 4 pieces. Each piece of dough will make 12 -2 inch taralli. Using the palms of your hands and applying gentle pressure, roll the dough into a rope of approximately 1 cm wide. Pinch both ends together to form a circle. Place each taralli on a parchment paper covered baking sheet.
Repeat with the remaining dough.
Bake for 30-40 minutes until lightly golden and crisp.
