From the brewery:

Pitch Black Dessert Sour - Smooth as velvet, black as night. Introducing an evolution of our jet-black dessert sour that defies expectations. Inspired by a traditional red velvet cake, we’ve blended juicy blackberries, cherries, velvety chocolate, smooth caramel and creamy vanilla in every sip. The darker half of our Velvet duo: Black Velvet, if you please.
