Amargo Chuncho Bitters
According to Imbibe Magazine, "A Pisco Sour isn't the same without these."
From the Amargo Chuncho website: They are the original Peruvian bitters and are the only bitters for a truly authentic Pisco Sour. Chuncho is a complex and well balanced combination of over 30 various peels, herbs, roots, barks and flowers from the Peruvian forest – including Quina and Sarrapia leaves, both of which appear on the Peruvian flag – that are macerated then rested for six months in oak barrels before being bottled. The most common use is in cocktails, but these bitters can also be used across all areas of cooking.
This is a 75 ml bottle.
