From The Apothecary Bitters website:

The Darkness Cacao Coffee bitters are a rich blend of flavors with a deep chocolate essence, strong notes of coffee and a complex undertone of dark spices. Add to that a pleasant, warming bitterness and just a hint of orange and you're ready for The Darkness.

Spirits: These bitters work particularly well in brown spirits but they also offer an interesting play of flavors with mezcal or tequila.

Ideas: Try them in a Mai Tai, a Mint Julep or a Rob Roy.

Tasting Notes: Aroma notes of cacao, dark chocolate, coffee, spice and burnt orange. Taste follows with cocoa, dark chocolate, coffee, cinnamon, brown sugar and a subtle bitter note.
