Find Your Coffee

At cafehound.com, we endeavor to locate the best coffee in the world. Over the last eight years we’ve happily watched as globally, the options available to the public have exponentially increased and the public’s general awareness of specialty coffee has deepened. Although we still believe that tracking down the best coffee in the world is central to our mission, we recently decided to dip our toes into the area of recommending specific coffee(s) to coffee lovers based on a mixture of qualitative and empirical analysis.

espresso_2017

In two posts (1 and 2) from 2015, we took verbal reviews of specialty coffees from the site coffeereview.com,  and we employed various clustering algorithms to discover groupings of coffee (based on words used to describe them and other factors). This served as our initial foray into using Data Science on expert coffee reviews to improve our understanding of specialty coffee.

Over the past month, we’ve set out to improve upon that original work in order to empower java lovers to discover the perfect brew. Our years of cupping coffee and talking with experts have shown that – after a certain point – what constitutes a “good cup of coffee” is subjective and specific to the palette of the beholder.

With that in mind, cafehound.com chose to use a large, multiyear list of coffee reviews from Kenneth David’s coffeereview.com site to explore the relationship between the descriptions used to rate coffee aroma, flavor, aftertaste, body, acidity and finish. We hypothesized that there are distinct groupings of coffee based on their roast profile, body, and flavors that are relevant to informing consumer preferences in the overall marketplace. To clarify, a market segmentation based on a representative sample of surveyed consumer preferences may be more useful to marketing professionals, but that is outside of the scope of this post. Instead, we’re using the structure inferred from math and reviews of specific coffees to estimate categories of the potential “coffee experience.” These categories may provide coffee consumers with guideposts for exploring new specialty coffees.

Our results led to six broad categories of coffee that we’ve ordered from lightest to darkest roast (based on average Agtron ratings). Agtron ratings are a numerical representation of the consistency of the roast color (lower numbers indicate a darker roast <45, higher numbers indicate a lighter roast 50+). More than the roast determines the flavor profile and overall body of the coffee, which is why some of these segments may appear similar.

Initially, we bring this content to you via occasionally updated web pages. Depending on demand, we may scale our service to provide daily or weekly recommendation updates.

Shiny Segmentation and Prediction

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.

List of Segment Two Coffees

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.

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.

Cafe Hounding: Sightglass Coffee Bar & Roastery – San Francisco

270 Seventh Street
San Francisco, CA
sightglasscoffee.com

P1000765

Sightglass Coffee Bar & Roastery has already garnered a lot of attention even though they just opened the kiosk three months ago and the “real” coffee bar and roastery are still under construction. It is located in San Francisco’s SoMa neighborhood on 7th Street at Falsom– a short walk from BART Civic Center station.

I visited Sightglass in the morning of a weekday. At first, I was a bit disappointed that the cafe seemed to be closed and there was construction inside the building. A second later, I smelt strong coffee aroma coming from inside so I kept walking down to what was once a driveway to a warehouse. Finally, I spotted the coffee kiosk inside the garage gate.

Sightglass is owned and run by the two brothers who are also the roasters, and apparently the contractors and constructors, of this coffee bar. They were originally from the Pacific Northwest so coffee is in their blood. They helped start Four Barrel Coffee in the Mission, and before that worked at Blue Bottle (which we reviewed here). People from Blue Bottle also help the brothers set up their new cafe. Jared also worked together with Eileen Hassi, the owner of Ritual Coffee, back while they both were in Seattle. All of these confirmed what Eileen told me during an interview with her that the gourmet coffee industry in San Francisco had a healthy “friendly competition.”

P1000764

I enjoyed my latte while watching Justin and Jared working and supervising the construction of their new coffee bar. Right now they use coffee beans from Verve Coffee Roaster in Santa Cruz, CA, but plan to roast their own beans in a month. (I already spotted a Probat roaster there.) With their past roasting experience at Blue Bottle  among other places, the quality of the beans they will offer is likely guaranteed.

I had a conversation with Justin who shared with me their vision. According to him, the building was a paint warehouse so it has gigantic size as compared to the usual neighborhood coffee houses. The ceiling is high and the place is very airy. They will have a mezzanine that people can sit and enjoy their drink. The coffee bar will be in the back while the roasting area will be in the front. They plan to have seating area around the roaster as well. They hope that the construction should be done in a few months. And I am looking forward to going check out the place and tasting their own roasted coffee soon.

Cafe Hounding: Local 123 – Berkeley, CA

2049 San Pablo Avenue
Berkeley, CA

P1000757

Local 123 is a new cafe in Berkeley, CA. Even though it has been open for just five months, this coffee house has attracted great reviews. I visited Local 123 during the day on Saturday. The location is a bit far from the campus so either you have to walk quite far or you can take a bus to University and San Pablo.

Picture 1

Local 123 uses coffee beans from Flying Goat Coffee in Healdsburg (near Santa Rosa), CA. The beans are generally medium mild roasted. For espresso drinks, the default beans are Flying Goat’s espresso blend No. 9, but they are also available with single origins upon request. When I visited the cafe, the featured single origin was Costa Rica Puente Tarrazu. For drip coffee, Local 123 offers several single origin beans for you to choose. Then they freshly grind your beans and make your drip coffee cup-by-cup. I find this attention to quality as a big plus. I ordered latte as usual. My drink was prepared by Frieda, who was also a co-owner of Local 123 along with her sister-in-law. The latte was beautiful. It was mild and taste great. Frieda was friendly and attentive to the coffee she brewed.

Picture 2

Local 123 has minimal decoration with some artworks on the wall. The cafe is clean. It seems to be famous for people who come with their laptops or books and spend time working while enjoying their drinks. The cafe offers free wifi throughout but also has the “wifi-free” area that encourages conversations among customers. There is also outdoor seating area in the back. They also have selected homemade pastry, sandwiches, and salad available. And they make jams from locally-grown fruits. The only problem that some customers may have is that this cafe takes cash only and do not accept credit cards. There is an ATM machine nearby however.

P1000763

Overall, Local 123 is also a lovely neighborhood cafe that not only provides good coffee but also pays a lot of attention to sustainability and local community. (Big kudos on that!) As some of the reviews on the internet proclaim, if you are in Berkeley and don’t want to travel to San Francisco to get Blue Bottle coffee, Local 123 is the place that you will unlikely to get disappointed. So far, I do agree with them.
