Data Science: Exploring CoffeeReview.com Top Coffees (Cntd.)

In the last post we began exploring the relationship between the language describing coffee (“cupping notes”) and price/brand/roaster. Our objective is to provide coffee consumers with a general understanding of particular groupings of coffee they can choose based on flavor profiles and mouthfeel characteristics. An example of the type of properties coffee professionals use to describe their craft is illustrated in the below flavor wheel from Counter Culture:

CC_FlavorWheel

After evaluating the segments that our initial k-means clustering (with a k of 5) produced, I was unsatisfied with the results. My decision to haphazardly throw the price variable (unscaled) into the model was wrong-headed and drove the algorithm to essentially classify segment membership solely based upon that. In some cases such an exercise may be useful, but for our objective of discerning whether specific language could be used to segment particular specialty coffees, this segmentation wasn’t going to do it for us.

Also, this initial segmentation helped me narrow my “business objective”. Now I wanted to segment by flavor profile, something that might actually help inform a potential consumer’s purchasing decisions.

In order to develop the cupping note variables that would inform our segmentation, I explored the text data from Kenneth Davids’ site and selected the most common and/or most distinguishing words to test. The list of words is below.

wordlist

A quick look at these led me to believe that certain words might not yield significant information gain in the algorithm due to lack of variance. Mouthfeel, sweet and acidity were present in 96%, 80% and 90% of reviews respectively. Their power as differentiating variables would be constrained by their existence in nearly all observations (with the possible exception of acidity).

However, in my initial quick cluster using SPSS, I included the three variables mentioned above and I still liked the results enough to move forward.

Segment 1: 16.9% of reviews

Segment 1: 16.9% of reviews

This segment was the most expensive (average $42.31 USD per pound) and highest rated (94.6). The segment was the highest indexed on floral, honey, complex, silk, delicate, intense, and peach cupping notes. It also indexed highly on nib, lemon and acidity. The most common producer countries in this mix were geisha panama and Colombia, Ethiopian, Kenyan and El Salvadoran coffees.

Segment 2: 27.8% of reviews

Segment 2: 27.8% of reviews

This segment was the least expensive (average $26.72 USD per pound) and moderately rated (94.45) while coming from the most diverse sampling of producer countries. It indexed highest on rich, deep, resonant and pungent cupping notes. Whereas the other segments did not include any coffees from Bolivia, Brazil, Mexico or Papa New Guinea, this segment did.

Segment 3: 13.9% of reviews

Segment 3: 13.9% of reviews

This segment was middle of the road in terms of cost and ratings (average $37.09 USD per pound and rated 94.52 on average). It indexed highest as juicy, tart, acidity, nib, bright, sweet, and was also well above average in complexity and floral notes. The range of producing countries varied quite a bit in this segment, with several bourbon varietals from Guatemala, Costa Rica, Hawaii – still other Geishas from Panama, Colombia and Guatemala – several Ethiopian Yirgacheffe coffees and a few honey processed coffees from El Salvador (Pacamara) and Hawaii (Maragogype ($75/lb)).

List of Segment Three Coffees 

Seg3_L1 Seg3_L2

Segment 4: 20.3% of reviews

Segment 4: 20.3% of reviews

This segment was the least expensive ($28.46 USD per pound) and lowest rated (94.33) – all things relative to a very highly rated group of coffees. It indexed highest for fruit, sweet, lemon and light while also coming in pretty strong in the tart department as well. This segment is composed of a mixture of coffees from Ethiopia, Kenya, Burundi, Indonesia and Honduras. A few peaberry coffees are included, the red caturra from Rusty’s Hawaiian, a few stray Geisha coffees, and a decently heavy sampling of Sumatra, Yirgacheffe, Sidamo, and various Kenyan single-origins. For the value, this is a very attractive and diverse segment of coffees. See our site visit to Rusty’s in Hawai’i in 2011.

Segment 5: 21.1% of reviews

Segment 5: 21.1% of reviews

Segment five is highly rated (94.58) and quite expensive ($37.73 USD per pound on average). This segment indexes the highest for tart, rich, acidity, syrup, pungent, and mouthfeel, while also scoring highly for honey and bright notes. Panama, Colombia, Hawaii and Ethiopia are the most heavily represented producer countries in this grouping. This segment is probably the most populated by Geishas followed by exotic Ethiopian and Kenyan coffees.

Buzz: Starbucks Unveils High-End Roastery-Tasting Room Concept 

 

Starbucks Reserve.

Using a barrage of adjectives like super-premium, unique, reserve and small-lot, Starbucks has just announced details regarding its new “premium coffee experience” store concept, as well as its flagship “small-batch” Roastery and Tasting Room, coming to Seattle’s Capitol Hill this winter.

The company says the new roastery will be a kind of interactive coffee museum and tasting room designed to showcase the company’s “small-lot” Reserve line of coffees. It will also be the flagship for Starbucks’ new store model, which will occupy some 100 locations in strategic markets throughout the globe over the next five years.

Adjectives abound, but if one phrase is an elephant in this particular room, it is “Third Wave,” one many around the high-end retail industry, including this blog, has avoided using for years. But it seems particularly apt here, as the company that embodies “Second Wave”-ness rolls out its new high-end, coffee-quality-focused brand.

Starbucks itself describes the new store concept as is a kind of higher rung in “customer experience segmentation,” part of the company’s retail “evolution.” Starbucks CEO Howard Schultz went so far as to describe the new roastery and tasting room as something that will revolutionize all of specialty coffee.

(related: Drama Unfolds with the Opening of Williamsburg’s First Starbucks)

“Everything we have created and learned about coffee has led us to this moment,” he said. “The Starbucks Reserve Roastery and Tasting room is a multi-sensory experience that will transform the future of specialty coffee. We plan to take this super premium experience to cities around the world, elevating the Starbucks experience not only through these stores but across our entire business.”

Here’s more from Starbucks on the new Seattle roastery:

A first-of-its-kind union for Starbucks of coffee theatre and manufacturing, this iconic Seattle destination will allow Starbucks to double its small-batch roasting capacity and grow its Starbucks Reserve® coffee presence from 800 to 1,500 stores worldwide, by the end of FY15. More than two years in development, this unprecedented experience will allow customers to engage with Starbucks passion for coffee in a 15,000 square-foot interactive retail environment devoted to beverage innovation and excellence.

In addition to the approximately 100 new premium stores, Starbucks is also unveiling new smaller-footprint and drive-through “Express” store models, where there will be a focus on quick service and developing Starbucks’ mobile ordering platform. These stores, the company says, will “address the increase in urbanization and decentralization of retail.”

Including its traditional retail stores, its premium stores and its express stores, Starbucks is on track to open some 1,550 outlets globally in 2014, and plans to open 1,600 in 2015, including 300 net new locations in the U.S.

Ano Novo Blend & Universal Education

Ano Novo Blend: Give the Gift that Keeps on Giving

The first custom Cafe Hound blend of 2010 is already receiving raving reviews from its first consumers!  As we continue to sell out our limited stock we are closely approaching our goal of having enough money to send a charitable donation to the Barefoot Foundation (Pies Descalzos) down in Colombia.  Below are some success stories from the English version of their website.

Success Stories

The stories from the communities we serve inspire us to continue working for those who need us most. These comments from our students and their families describe the changes in their communities. For each success story, there are thousands more children who we hope to serve soon.

Ferley’s Story

Ferley didn’t think he’d ever get to go to school. His thin frame is shrunken by congenital rickets, making him look closer to six than to his eleven years. His mother Clarisa said, “I was afraid that if I let him go to school, the other kids would call him names and make fun of him, and that he would be a burden on the teachers.” Clarisa Rentería and her five children are refugees who fled the violence of Colombia’s civil conflict, eventually settling in Quibdó, a western Colombian city. She explains, “I arrived here in 1999. It was heartbreaking to lose it all and be left with nothing.” The family struggled to survive and could not afford a wheelchair for Ferley. Without a wheelchair, Ferley could not get around the rocky streets.

However, Ferley didn’t want to stay confined to the house. He begged to go to school and longingly studied his siblings’ homework. Pies Descalzos visited Ferley’s house and talked to his mother, convincing her that her son would be well taken care of. When Clarisa saw the desire and determination in her son’s eyes, she agreed. Pies Descalzos bought Ferley a wheelchair and he enrolled in the Pies Descalzos School.

Four years later, Ferley is a happy, popular student who always has a smile on his face. He and his best friend Bryan are inseparable and they dream of continuing their studies. “I like to go to school because I learn a lot and because I like to share with my friends.” Ferley loves math, social science, reading and dreams of becoming a professional singer of Vallenato, a Colombian folk music style.

To teacher Absalón Asprilla Gómez, Ferley is a special student. “When I face something difficult, I don’t complain, instead, I think about his situation. He is one of the best students in the school, with a permanent smile, despite it all. For me, this is very meaningful. It has helped me grow a lot as a person.”

Pies Descalzos hasn’t just changed Ferley’s life; it has changed his whole family. Clarisa earns extra money for her family by preparing breakfast and lunch for the Pies Descalzos Foundation school as part of the “If I eat better, I will learn more” program. “We prepare lunch for the students and we help with the breakfast, so that they have food and they can study with full stomachs,” says Clarisa proudly. The meals they prepare are supervised by a nutritionist and made possible through Pies Descalzos and the Instituto Colombian Bienestar Familiar. This program helps make sure that the malnutrition that affected Ferley doesn’t affect other children.

The Barefoot Foundation helps hundreds of families like Clarisa and Ferley’s. The Pies Descalzos schools are open to everyone and serve as a center for community development. Parents, neighbors and grandparents learn sewing, artisan skills and literacy while teens engage in micro-businesses, sports leagues, and leadership development activities. This neighborhood is changing and growing thanks to the community, and the Barefoot Foundation and the Pies Descalzos Foundation.

The Story of El Minuto de Dios School, Altos de Cazucá

Elementary school teacher Consuelo Pachón barely recognizes her school, El Minuto de Dios, anymore. She teaches in Soacha an area south of Bogotá that was once a booming mining town. Today, its hills have been stripped of their natural resources, the mines left behind environmental damage and the jobs disappeared. The vacuum left by the mines has been filled with desperately poor people and internal refugees from Colombia’s civil conflict. Thousands flood in each year with nothing but their lives. Fifty-three percent are younger than 14 years old and many children have missed years of school while fleeing.

Before Pies Descalzos Foundation, El Minuto de Dios was in shambles. “At the start it was very hard. The school room walls were made of spare wood, the same kind they use to make fruit crates. The stairs were carved out of mud and, whenever it rained, the children slipped and fell. There weren’t bathrooms, just a latrine. “But now, the conditions have changed tremendously” she commented, raising her eyes to the ceiling in thanks.

The Pies Descalzos Foundation rebuilt the school; they installed sturdy buildings, libraries, computer rooms and safe bathrooms. Pies Descalzos, in alliance with the International Organization for Migration (IOM), the government, and Secretary of Education of Soacha, the Minuto de Dios University and the Educational Alliance, support two schools in Altos de Cazucá. In each, they provide nutritious meals, extra programs for troubled kids, recreational and leadership programs, while supporting parent cooperative that help families leave poverty. The community and the children have a safe, supported place to develop. As Ana, one of the school’s parents said “they now have the possibility to imagine a tomorrow filled with human and professional possibilities in this society.”

Jhonathan’s story

Jhonathan wants to clean up Altos de Cazucá. The 17 year old environmental biology major at Jorge Tadeo Lozano University knows only too well the pollution that plagues this poor area south of Bogotá. He moved to Altos de Cazucá as a baby with his mother and siblings. The family struggled to eke out a living, but his mother wanted more for her children so she enrolled them in the Gabriel Garcia Marquez Institute, one of the Pies Descalzos schools.

“The Foundation radically changed my life,” says Jhonathan.  “It taught me to relate to other people and that material things aren’t the only things that count. It helped me realize what my life’s project should be.”  With Pies Descalzos’ support, Jhonathan scored among the highest students in the country on the high school exit exams. He and other top Pies Descalzos students received university scholarships from Pies Descalzos to pursue their dreams.

“The University is an enormous responsibility, not only for myself and my family, but to help the rest of my community,” says Jhonathan. He and another student, Maicol, are using their education to create a recycling business that will provide much needed jobs and help clean up the local environment. Jhonathan also returns to his old neighborhood to tutor kids in school and help them imagine their true potential. “We use games to make learning fun and to expand their interest in school” says Jhonathan.

He loves learning and is eager to continue studying. He would like to pursue a master’s degree in systems engineering and learn French and Portuguese. But, no matter how far he goes, he will never forget the Pies Descalzos Foundation, the Barefoot Foundation and the lessons they taught him about service and believing in his own potential.

Order Now!!! Ano Novo 2010 Blend by Kris/Maher

For information and order, contact maher@cafehound.com or krislert@cafehound.com

In tribute to the new year, Cafe Hound presents to you the ANO NOVO 2010 Blend. Ano Novo means New Year in Portuguese and reflects our appreciation to Novo Coffee in Denver, Colorado, who perfectly roasted the beans for us. Concocted by Matthew Maher and Krislert Samphantharak, the blend mixes the best seasonal fair-trade and organic coffees of South America and Africa to provide a sophisticated, bright, and balanced flavor profile good for drip, press, or espresso brewing. The blend will give you a perfect beginning of 2010. All net proceeds will go to charity.

Specific coffees found in our blend include:

– Amaro Gayo Sun-Dried: Amaro, Ethiopia – Full body with a grassy overtone and nuances of strawberry, apple, chocolate and unripe banana.

San Rafael: Concordia, Colombia – This coffee has a strong acidity (tangerine nuances) followed by smooth finishing woody nuances. Very bright.  The coffee comes from the San Rafael estate of the Concordia municipality in the Department of Antioquia in Colombia. Maher has personally visited a number of coffee farms in this region of Colombia.

– Kenya Gatina: Nyeri, Kenya – A woody well balanced coffee with blueberry undertones that compliment the brighter elements of the previously mentioned coffees.  This coffee is quite different than the Ndaironi region releases that were on the market in mid-2009 and is far too berriful as a single-origin.

– Ojo de Agua: Volcan, Panama – Very balanced  mild citrus nuance with very silky finish.  Mixture of peanut and chocolaty nuances in the aftertaste.  At first appears uninteresting next to the sun-dried but in the end wins out on its “drinkability” and balanced finish. Novo has shared some additional details on the Ojo de Agua coffee from the Finca Hartmann in Panama.

“Some of the hardest-working and most environmentally committed coffee producers in the world, the three generations currently represented at Finca Hartmann all have a hand in daily operations. Much of the family’s land is primary forest and rests contiguous with the enormous Parque Nacional La Amistad, Central America’s largest national park. Despite uncountable offers to cut the forest for large monetary gain over decades, the Hartmanns remain committed to a future of coffee in balance with nature. The Hartmanns have a cupping lab on site and are leaders in coffee production for quality. Their expertise has been enjoyed beyond their own farm as they act as consultants for many Panamanian and other Latin American coffee producers.”

For ordering information please contact maher@cafehound.com . We encourage you to donate $10 for each half pound of coffee that you order (before shipping if you want it shipped).  As we manage the legal obstacles for setting up money transfers to our foundation partners in Colombia, Guatemala, Brazil, Nicaragua, Thailand, Indonesia and Vietnam – we will be giving all profit from the ANO NOVO 2010 Blend to a local food bank in Arlington, Virginia.  We will only have a limited amount of this very special blend so please place your order now, before it is too late!

Regards,

– The Hounds
