Preheat oven to 350 F. Lightly grease an 8- or 9-inch springform pan and dust it
with cocoa powder.

In a large bowl, sift together flour and cocoa powder.
Stir in sugar, baking soda and salt. Pour in vegetable oil, vanilla extract and red
wine and whisk until batter is smooth and no streaks of dry ingredients remain
visible. Pour into prepared pan.

Bake for 25-30 minutes (an 8-inch pan may take 30-35 minutes), until the cake is
set and a toothpick inserted into the center comes out clean or with only a few
moist crumbs attached. Allow cake to cool completely in the pan before frosting
with Dark Chocolate Wine Ganache
