Coarsely chop 300 g of dark chocolate coating and melt over a warm water bath. Leave to cool slightly. Roast the almonds in a pan without fat, remove and chop coarsely. Cream fat, salt, vanillin sugar and sugar with the whisk of the hand mixer. Stir in eggs one after the other.
Mix flour and baking powder and stir in. First let the chocolate coating shrink while stirring constantly, then stir in red wine. Fold in almonds, spices and orange peel and fill the dough into a greased, flour-spreaded ring cake tin (2 litres capacity). Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: level 2) for 55-65 minutes (test with a stick, the dough should stick slightly to the stick). Remove from the oven, leave to rest for approx. 15 minutes, turn out of the tin onto a cake rack and allow to cool. Coarsely chop white couverture and 150 g dark chocolate separately and melt in a bowl over a warm water bath. Stir 5 g coconut oil into the white chocolate coating and 15 g into the dark chocolate coating. First coat the cake with 3/4 of the dark couverture, then lightly marble with the light and remaining dark chocolate coating. Put the cake in a cool place.
