Many people see the word "COE" on coffee packaging when choosing coffee, but may not be clear about what it actually means. Cup of Excellence (COE for short) is a rating system for specialty coffee that scores and ranks coffees through multiple rounds of rigorous cupping, ultimately awarding the COE title to the most outstanding lots. This system was first introduced in Brazil in 1999 by a group of coffee producers, and subsequently spread gradually to producing countries such as Colombia, Guatemala, Panama, Costa Rica, and Nicaragua. For estates, receiving COE not only means honor, but can also fetch high prices in international online auctions, while boosting the profile and trading volume of the producing region. This article will unfold from three aspects—origin, competition process, and impact—to help coffee lovers understand the meaning and value of COE. [more…]
