Preheat the oven to 350 F. f using a black Bundt pan, 325 F. I always use 325 F.
Grease and flour a 12-cup bundt pan or spray it with flour-added cooking spray.
Whisk the flour, cocoa powder, baking soda and salt together in a bowl.
Cream the butter and sugar in a large mixing bowl using a hand-held mixer. Beat for about 4 minutes. Add the eggs and beat until incorporated. Beat in the vanilla, scraping sides of bowl. Beat for about two minutes.
By hand or using lowest speed of mixer (best by hand) add the flour mixture and wine alternately beginning and ending with flour mixture.
Pour into pan and bake on center rack for 45 minutes or until a tester inserted comes out clean. Let cool for 10 minutes. Flip from pan.
