BOP

As the world's first green bean competition, the emergence of BOP can be seen as Panama's specialty coffee industry's strategic move in the coffee market at that time. Through this successful strategy, Panama created a blue ocean focused on quality over quantity. Every year, auction beans from here fetch prices of hundreds of dollars. FrontStreet Coffee believes that BOP has played a very important role in promoting quality cultivation of Panama's coffee.

In 1995, seven coffee-producing families in Panama jointly established the Specialty Coffee Association of Panama (SCAP). In 1996, they founded the first Panama green bean competition - Best of Panama (BOP).

Starting in 2004, SCAP organized the first Best of Panama (BOP) auction, with only 11 lots of beans, averaging $2.89 per pound. By 2012, this figure reached $24.83, greatly encouraging and promoting the development of specialty coffee. The renowned Hacienda La Esmeralda, Don Pachi Estate, Carmen Estate, and Elida Estate were all founding estates.

Coffee plantation landscape

In 1964, American banker Rudolph Peterson retired, moved to Panama, and purchased Hacienda La Esmeralda in Boquete, initially focusing on dairy production. Later, his son Price resigned from his medical position to help his father manage the farm. In 1987, they introduced Caturra and Catuai coffee bean varieties, and in 1994 established a washing station, giving them their own coffee processing facility.

Currently, Hacienda La Esmeralda has three main estates growing Geisha varieties: El Velo, Cañas Verdes, and Jaramillo. In 1996, they acquired the nearby Jaramillo estate, which had superior geographical conditions and good flavor profiles from existing coffee varieties. El Velo was acquired by Hacienda La Esmeralda in 2012. FrontStreet Coffee believes that Hacienda La Esmeralda's decision to acquire estates with high-quality products at high altitudes was unique at the time, allowing the estate to occupy a significant position in the coffee industry.

The Jaramillo estate is where Geisha varieties are cultivated. Due to its low yield, the previous owner used it primarily as a windbreak tree until it was acquired and its exceptional flavor was discovered. FrontStreet Coffee feels this is precisely the charm of Geisha coffee - the more adverse the growing environment, the better the flavor expression.

Although Hacienda La Esmeralda initially discovered coffee beans with flavor characteristics, for precision, they cupped coffee beans from different areas of the estate, determining planting plots based on altitude. This led to the Red Label, Green Label, and Blue Label Geisha grades we know today, all classified by altitude. FrontStreet Coffee will explain this content in detail below.

Beginning with winning the Panama green bean competition BOP in 2004, they continued to achieve remarkable results. Later, expert identification revealed that this coffee bean was the Geisha variety from Ethiopia. Since then, the Peterson family has focused most of their energy on developing infrastructure to support excellent batch separation and refined processing.

COE

C.O.E. refers to Cup of Excellence, an international coffee cupping competition. C.O.E. evaluation is the most credible among top-tier coffee competitions. Outstanding candidates who emerge from rigorous competition represent the highest quality coffee from that country for that year. They must maintain high scores consistently throughout each cupping to rank among the top, and only then can they receive the C.O.E. award designation. Coffee beans from winning estates are auctioned through unified specific online auctions, allowing buyers worldwide to bid in an open and transparent manner. This approach rapidly spreads the reputation of excellent award-winning farms while ensuring competition batches receive better prices.

The competition is generally held annually, with specialty coffee growers submitting their best coffee beans to domestic or international judges from the association. Participating coffees must undergo strict competition rules, with final winning estates typically passing through six rounds of screening. Usually, from 500 farms, fewer than 30 remain in the final selection. Therefore, Cauca Cup of Excellence and COE are two different concepts of competition.

First held in Brazil in 1999 by the Alliance for Coffee Excellence (ACE), it is currently the world's most renowned and authoritative specialty coffee competition, and also the most credible among top-tier coffee evaluation competitions.

Every coffee that wins in C.O.E. must have its own unique characteristics. To emerge victorious among numerous farms, it must undergo rigorous challenges and be of superior quality among many farms. Competition beans themselves have very few defects and insect damage, with high consistency in bean size and similar color. Even after roasting, expansion degree and coffee coloring are consistent. The flavor reflects growing environment, soil, terrain, and even green bean processing methods, creating unique flavors. Although coffee beans produced on the same farm have relatively small differences in various conditions, competition beans are definitely the best beans selected from the farm.

With C.O.E. competition experience, it's easier to establish information and contact with foreign buyers in production, transportation, and marketing. It can help foreign buyers resolve concerns. For small-yield farms of about 30-40 bags, it's easier to trade directly with more foreign small-scale coffee buyers without going through intermediaries or large coffee traders, benefiting both parties. Besides eliminating profits for intermediaries or large coffee traders, it mainly saves freight and tariffs between countries, which is the driving force for coffee producers' efforts.

Award-winning estates receive C.O.E. recognition for their quality improvement efforts. Not only do they receive major awards, but farmers' efforts also receive deserved prices and returns. Participating in C.O.E. competitions not only encourages farmers to dedicate themselves to improving quality and enhancing coffee bean levels but also helps create a specialty coffee market.

At FrontStreet Coffee, you can also find beans that have won in COE cupping competitions! For example, the Pache and Pacamara from Guatemala's Little Blueberry Estate, as well as beans from Brazil's Shenmu Estate. In the first Ethiopian COE competition in 2020, FrontStreet Coffee also participated in the bidding for one of the lots.
