Amargo Chuncho, or Chuncho Bitters, were named after the ethnic group of Amazon Indians that resisted the Spanish Conquistadors. 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 Quinoa and Sarrapia leaves - 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.
