Combine first 5 ingredients. Cut in butter with a pastry blender until crumbly. Stir in caraway seeds and white wine.
Shape dough into a ball, and roll out to 1/4-inch thickness on a lightly floured surface. Cut with a 2-inch round cutter, and place on a lightly greased baking sheet.
Bake at 375° for 15 to 20 minutes or until lightly browned (may be slightly soft in center). Transfer to wire racks to cool.
