Unit 3: Frequently Used Terminology Unit 3: Frequently Used Terminology The Coffee plant is defined as a woody perennial evergreen dicotyledon, belonging to the Rubiaceae family1. Commercially grown types of coffee are Robusta (Coffea canephora) which accounts for ~20 percent of world production, Arabica (Coffea arabica), ~80 percent and Liberica (Coffea exelsa), with limited market demand for the latter. Other lessor known cultivars are Catimor, Bourbon and Typica which are seldom grown commercially. Cultivars are varieties produced by agricultural techniques and are not normally found in nature. Most of the known varieties in specialty coffee are really cultivars2. Varieties are diverse subspecies derived from selective breeding or natural selection of coffee plants2. Examples Name Species Region Comments Blue Mountain C. arabica Blue mountain region, Jamaica unique mutation of Typica variety Arusha C. arabica Mount Meru, Tanzania Typica variety or a French Mission Shade Grown also referred to as Bird Friendly is coffee grown in the forest which serves as a natural habitat for insects and other animals. Processing: Drying is the process of removing excess moisture so the beans can be stored. This is done if the beans were processed using the wet method. Once the beans are dried they are known as parchment coffee and are then moved to storage. Hulling/Milling is the process of removing the outer parchment layer from the bean after drying and can be done either at a hulling station or manually3. The milled beans are now referred to as green coffee. Parchment skin is what is left once the pulp has been removed completely after the fermentation process has been completed. Dry Processing involves drying the cherry without removing the pulp4. Wet Processing involves the floating of the cherry in water, washing and pulping to separate the pulp from the parchment skin5. 1 Coffee Research Institute, 2001, Arabica and Robusta Coffee Plant 2 Wikipedia, List of Coffee Varieties 3 National coffee Association, About Coffee, 10-steps-from-seed-to-cup 4Fintrac, USAID/Honduras, 2000, The US Market for Specialty Coffee 5 CAFÉ Africa Guide, 2014, Trainers Guide, First Edition, Uganda Ministry of Agriculture, Animal Industries and Fisheries 2018 1 Fintrac University Pulping is the process of removing the skin and pulp from the beans before the fermentation process takes place (usually in the wet process). The fermentation process allows for the removal of all the pulp. Washing is the process of removing the skin of the cherry. Marketing/Distribution: Barista is a person whose job it is to prepare and serve different types of coffee6. Brewing coffee determines how the final cup will taste and there are many methods to brewing coffee. Both the type of roast, the type of water, the time taken and the equipment used to brew are important in the final taste of the coffee. Cupping is the process of testing coffee to determine quality. The coffee is ‘nosed’ then tasted and subtle differences in the characteristics of the coffee are noted7. Gourmet/Rare Origin/Estate refers to coffees sold at premium prices based on a specific production location and perception of high quality. Examples are: Jamaican Blue Mountain, Hawaiian Kona Fancy, Haitian Bleu, Ethiopian Yirgacheffe and Kenyan AA. Grinding allows for different consistencies of coffee to extract the flavor. Beans vary from course to fine, with the finer grinds being the ones that should be prepared quickly, e.g. expresso. Fair Trade is coffee purchased from a certified “Fair Trade” producer. They buy coffee from producers at a guaranteed minimum price. The coffee is priced at a premium to the consumer based on the Fair trade ethos of providing a living wage to producers and removing the middleman from the marketing/selling of the coffee8. Rainforest Alliance is a certification system which educates farmers on how to reverse the intensive management systems used when growing industrial coffee hybrids. They work on encouraging sustainable production and harvesting8. Roasting involves taking the green beans and placing them into a roasting machine at temperatures in excess of 5000F, where they turn brown and produce the characteristic coffee aroma. There are different types of roast which also determine the final taste of the coffee, e.g. medium or dark roast. The beans are then cooled immediately and are now ready for grinding. Single origin is a label that indicates that the coffee is sourced from one single producer, crop or region in one country. This allows it to be easily traceable. It is a specific coffee, not a blend, and is usually of higher quality9. Specialty is defined as any quality coffee and includes all coffees in the gourmet, rare origin, estate, Fair Trade, Rainforest Alliance, Single origin, Organic, etc. Specialty coffee can be marketed by country of origin or method of production and is usually of the Arabica variety10. Specialty coffee must also have a rating of over 80 points.

The amount of caffeine in a cup of coffee will vary based on the bean, how it is roasted and brewed. In brewed coffee the average amount of coffee is 95 mg with a range from 75-165mg11. Decaffeination is the process of removing most of the caffeine from the coffee. Brewed decaffeinated coffee has on average 2 mg of caffeine12. 11 National coffee Association, About Coffee, 10-steps-from-seed-to-cup 12 National coffee Association, About Coffee, 10-steps-from-seed-to-cup 2018 .

  • Coffee Flavor and Flavor Attributes That Drive Consumer Liking for These Novel Products
    beverages Review Coffee Flavor: A Review Denis Richard Seninde and Edgar Chambers IV * Center for Sensory Analysis and Consumer Behavior, Kansas State University, Manhattan, KS 66502, USA; [email protected] * Correspondence: [email protected] Received: 1 June 2020; Accepted: 3 July 2020; Published: 8 July 2020 Abstract: Flavor continues to be a driving force for coffee’s continued growth in the beverage market today. Studies have identified the sensory aspects and volatile and non-volatile compounds that characterize the flavor of different coffees. This review discusses aspects that influence coffee drinking and aspects such as environment, processing, and preparation that influence flavor. This summary of research studies employed sensory analysis (either descriptive and discrimination testing and or consumer testing) and chemical analysis to determine the impact aspects on coffee flavor. Keywords: coffee flavor; processing; preparation; emotion; environment; consumer acceptance 1. Introduction The coffee market is currently worth USD 15.1 billion and growing. This market is mainly comprised of roasted, instant, and ready-to-drink (RTD) coffee [1]. The flavor of a roasted coffee brew is influenced by factors such as the geographical location of origin, variety, climatic factors, processing methods, roasting process, and preparation methods [2–10]. The differences in sensory properties can, in turn, affect consumers’ preferences for and emotions or attitudes toward coffee drinking [11]. 1.1. Motivations for Drinking Coffee As indicated by Phan [12], the motivations for drinking coffee can be grouped under 17 constructs: liking, habits, need and hunger, health, convenience, pleasure, traditional eating, natural concerns, sociability, price, visual appeal, weight control, affect regulation, social norms, social image [13], choice and variety seeking [12,14,15].

  • Creolé Coffee1
    International Food and Agribusiness Management Review Volume 7, Issue 2, 2004 Creolé Coffee1 Lynn Kennedy ai and Elizabeth D. Roule b a Alexander Regents Professor, Department of Agricultural Economics and Agribusiness, Louisiana Agricultural Experiment Station, Louisiana State University Agricultural Center, Baton Rouge, LA. b Research Associate, Department of Agricultural Economics and Agribusiness, Louisiana Agricultural Experiment Station, Louisiana State University Agricultural Center, Baton Rouge, LA. Abstract Creolé Coffee had just started to achieve regional and national success. However, recent volatility in the world coffee market resulted not only in price instabilities, but also created difficulty in procuring the high-quality product customers had grown to expect from Creolé. In examining this situation, Jim Brewer determined that the company must adapt their relationships with producers to ensure the availability of the quality and quantity of coffee needed to produce the premium blends consumers now associate with Creolé. In turn this would allow the company to provide consumers with a high quality product at a stable price. Key Words: vertical coordination, strategic alliances, risk management, international trade, commodity procurement. i Corresponding author: Tel: + 225-578-2726 Email: [email protected] Other contact information: E.

  • Customizing Beverages at Starbucks® Stores
    June 2020 Customizing Beverages at Starbucks® Stores With more than 170,000 ways to customize beverages at Starbucks® stores, customers can create a favorite drink that fits their lifestyle. To help guide our customers’ decision making, nutrition facts and ingredients for a majority of the beverages served at Starbucks are available on starbucks.com, on the menu boards in Starbucks® stores and on the Starbucks® mobile app. Below are barista tips on how to customize beverages at Starbucks, as well as a selection of drink recommendations to fit a variety of preferences. Barista Customization Tips • Ask for Starbucks Blonde Espresso: Try asking for Starbucks Blonde Espresso in your espresso beverage instead of the traditional Starbucks Signature Espresso baristas use (it’s no extra charge!). Starbucks Blonde Espresso is smooth and subtly sweet, making it perfect for unsweetened beverages like an Americano or Cappuccino – hot or iced. • Select your milk: Customers can choose from whole, 2% milk or nonfat milk, or non-dairy alternatives such as soy, coconut and almond. Customers can also try oatmilk at more than 4,700 stores in California, Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, and Wisconsin. • Ask for fewer pumps of syrup: To lessen the sweetness of your flavored beverage, ask for fewer pumps of syrup, or select a sugar-free syrup, available in Vanilla or Cinnamon Dolce. • Try a sweetener substitute such as Sweet’N Low®, SPLENDA® or Stevia Blend from Whole Earth. • Ask for “less whip” or “no whip” • Make it “Skinny:” Most handcrafted espresso and Frappuccino® blended beverages can be requested “skinny,” which means the beverage is made with nonfat milk, no whipped cream and a sugar-free syrup if available.

  • A Study Case on Coffee (Coffea Arabica): Limu Coffe
    A study case on Coffee (Coffea arabica L.) Limu Coffee Laurent Bossolasco Sous la direction de François Verdeaux Ethiopie, Octobre 2009 “It is also the coffee type. It took its name from the Kaffa province1 where it grows spontaneously, and where, once ripened, it is picked without any effort by the natives as a wild fruit. I found out about this in many scholarly books: all admit that south western Abyssinia is the only country of the world where coffee grows as a natural soil product. Weather conditions not found elsewhere in the universe, the alliance between tropical heat and mountainous altitudes realized in this Earth paradise the unique miracle.” Ménélik et nous, Hugues le Roux (Paris, 1903) Coffea Arabica L., as it has been written and rewritten, finds its birthplace in south western Ethiopian forests even if Linnaeus gave its scientific name in 1753 paying tribute to his future country. The relationship between Ethiopians and coffee is deep-rooted, and coffee production and consumption are closely intertwined with Ethiopian history, culture and economy. Coffee has been cultivated, traded and consumed over centuries and still play a significant role in the daily life of most Ethiopians and for the state of Ethiopia as a whole (Stellmacher, 2007). As told me Ato Tarreessa Fayisa, a peasant living Limu Genet (Limu Kosa woreda, Jima zone, Oromiya region): “Coffee is the backbone of our life”. Coffee production is of highest importance for monetary income generation, followed by honey and livestock production. Farmers realizing income through surplus of any production rely on coffee since the greatest share of income is gained through coffee production which is the surplus production archetype.

  • Assessment of the Genetic Diversity of Philippine Arabica Coffee (Coffea Arabica L.) Using SSR Markers
    Philippine Journal of Science 149 (3-a): 993-1003, October 2020 ISSN 0031 - 7683 Date Received: 18 May 2020 Assessment of the Genetic Diversity of Philippine Arabica Coffee (Coffea arabica L.) Using SSR Markers Miriam D. Baltazar1,2* and Jermaine Marie Ann O. Fabella2 1Department of Biological Sciences 2National Coffee Research, Development and Extension Center Cavite State University, Indang, Cavite 4122 Philippines Arabica coffee (Coffea arabica L.) plays a significant contribution to the Philippine coffee industry. Many important genes are continuously lost due to an increase in population, urbanization, and the promotion of registered and popular varieties in the country. This study was conducted to assess the genetic diversity of 27 Philippine C. arabica accessions currently maintained at the Cavite State University – National Coffee Research, Development and Extension Center (CvSU-NCRDEC) field genebank using 19 simple sequence repeat (SSR) markers. Around 80% of the markers used showed polymorphism. A total of 56 alleles were detected, 47 of which were polymorphic. The average number of alleles per locus (3.7) and the polymorphism information content (PIC) (~ 0.40) found in this study were higher than those reported in the literature. Duplicate accessions were identified despite their striking morphological differences, and differentiation of synonymous accessions was also noted. The average genetic similarity was 0.83 and ranged from 0.64–1.0. Overall, the genetic diversity of Philippine C. arabica collection was low. Nonetheless, the higher number of alleles and PIC obtained provide more information in the selection of materials that can be used as parents in hybridization works. Cluster analysis showed three major clusters: Cluster I consisted of most of the accessions from Benguet State University (BSU), while Cluster II consisted of all accessions from the Bureau of Plant Industry (BPI) except Yellow Bourbon.
