Sensory & Tasting
Cupping
Also known as: coffee cupping, SCA cupping, cupping protocol, coffee tasting
Cupping is the standardized professional practice used to evaluate the sensory profiles and quality of coffee beans. By following strict protocols established by the [Specialty Coffee Association](https://sca.coffee/value-assessment), cuppers assess attributes like [Acidity](acidity), [Body](body), and [Balance](balance). This objective method allows producers, roasters, and Q Graders to assign scores and identify defects across the global supply chain.
Key Takeaways
- Cupping provides a universal language for the coffee industry, enabling communication between producers in origins like [Kenya](kenya) and roasters worldwide.
- The process evaluates ten primary attributes, including [Sweetness](sweetness), [Aftertaste](aftertaste), and Uniformity.
- Standardization of variables—such as grind size, water temperature, and contact time—is critical to ensure that differences in the cup reflect the coffee's quality rather than brewing errors.
- Professional cupping is the primary tool used by the [Coffee Quality Institute](https://www.trabocca.com/coffee-knowledge/quality/why-we-use-the-sca-cupping-protocol) to certify Q Graders.
- The protocol is designed to identify 'defects' or 'taints,' which are negative flavors caused by poor processing or storage.

Definition
Cupping is the standardized professional method for evaluating coffee quality and flavor. Developed by the specialty coffee industry, cupping involves smelling and tasting coffee prepared through a controlled immersion method, then scoring specific attributes including fragrance, aroma, flavor, aftertaste, acidity, body, balance, uniformity, clean cup, sweetness, and overall impression.
Why It Matters
Cupping is the universal language of coffee quality evaluation. It enables buyers to compare coffees objectively, producers to understand how their coffee is perceived, and roasters to make informed purchasing decisions. The SCA cupping protocol produces a score from 0 to 100, with coffees scoring 80 or above qualifying as specialty grade.
Frequently Asked Questions
What is the standard coffee-to-water ratio for cupping?
The [Specialty Coffee Association](https://sca.coffee/value-assessment) protocol specifies a ratio of 8.25 grams of coffee per 150 milliliters of water. The water should be heated to approximately 93°C (200°F) and poured directly onto the grounds.
What score is required for a coffee to be considered 'specialty'?
A coffee must receive a total score of 80 points or higher on the 100-point SCA scale to be classified as specialty grade. Coffees scoring below 80 are considered commercial grade.
Why do coffee professionals slurp the coffee during cupping?
Slurping is a functional technique used to aerate the coffee and spread it across the entire palate. This atomizes the liquid, allowing the cupper to perceive both taste and retronasal aromas more effectively.
What does 'breaking the crust' mean in cupping?
After the coffee has steeped for four minutes, a layer of grounds forms at the surface. 'Breaking the crust' involves using a spoon to push these grounds aside, which releases a concentrated burst of aroma for evaluation.

Modern EraThe Third Wave Coffee Movement
The Third Wave coffee movement, which emerged in the early 2000s, represents a fundamental shift in how coffee is understood, produced, and consumed. The term 'Third Wave' was coined by coffee professional Trish Rothgeb (then Trish Skeie) in a 2002 article for The Flamekeeper, the newsletter of the Roasters Guild. The First Wave refers to mass-produced commodity coffee (Folgers, Maxwell House, instant coffee). The Second Wave refers to the espresso-based coffee culture popularized by Peet's, Starbucks, and specialty coffee chains in the 1970s through 1990s. The Third Wave treats coffee as an artisanal food product, like wine, emphasizing origin, varietal, processing method, roast level, brewing technique, and the relationship between producer and consumer. Third Wave coffee is characterized by light roasting, single-origin beans, manual brewing methods (pour over, AeroPress), transparency in sourcing, direct trade relationships, and an emphasis on the unique flavor characteristics of individual coffees.

The organization collaborates with breeders, farmers, and industry partners across more than 20 coffee-producing countries to ensure the long-term sustainability and genetic diversity of Arabica and Robusta coffee.
Coffee Competitions
Cup of Excellence
The Cup of Excellence (COE) is the most prestigious coffee quality competition in the world, organized annually by the Alliance for Coffee Excellence in coffee-producing countries. Since its inception in 1999 in Brazil, the COE program has discovered and rewarded the world's finest coffees through rigorous, blind cupping evaluations. Winning coffees are auctioned to international buyers, often fetching prices many times higher than commodity rates. The COE has revolutionized how the coffee industry values quality, creating direct economic incentives for farmers to produce exceptional coffee.
BaristaWorld Barista Championship
The World Barista Championship (WBC) is the premier international competition for professional baristas, organized annually by the Specialty Coffee Association (SCA) since its inception in 2000 in Monte Carlo. I consider the WBC the highest honor in the barista profession, where national champions from over 60 countries compete to demonstrate mastery of espresso preparation, milk beverage technique, and signature drink creativity. Each competitor must prepare four espressos, four milk-based drinks, and four signature beverages within a strict 15-minute time limit, while delivering a detailed presentation to a panel of certified sensory and technical judges. Judges evaluate across four categories: taste, technical skills, presentation, and cleanliness, with scores weighted toward sensory evaluation at approximately 50 percent of the total. The winner receives a cash prize, industry recognition, and a platform to influence global coffee trends. Past champions including James Hoffmann (2007), Andrea Allen (2021), Anthony Douglas (2022), and Boram Um (2023) have leveraged their titles to build influential coffee businesses and media platforms.
BrewingWorld Brewers Cup
The World Brewers Cup (WBrC) is the premier international competition dedicated to the craft of manual coffee brewing, organized annually by the Specialty Coffee Association (SCA) since its inaugural event in 2011. I regard the Brewers Cup as the definitive showcase of pour-over and manual brewing excellence, where national champions from over 40 countries compete to demonstrate mastery of extraction technique, water chemistry, and sensory calibration. Competitors brew three beverages using manual brewing methods: two using a compulsory coffee provided to all participants, and one open-service beverage where competitors select their own coffee and brewing approach. Judges evaluate across three categories: taste, technique, and presentation, with the highest weight placed on sensory quality. The competition has helped elevate manual brewing methods like the V60, Kalita Wave, and AeroPress from niche techniques to mainstream specialty coffee standards. Past champions including Erin McCarthy (2013) and Chloe Lai (2023) have used their titles to advance brewing education and equipment innovation globally.
RoastingWorld Coffee Roasting Championship
The World Coffee Roasting Championship (WCRC) is the premier international competition dedicated to the craft and science of coffee roasting, organized annually by the Specialty Coffee Association (SCA) since its inaugural event in 2013. I consider the WCRC the definitive proving ground for roasting expertise, where national champions from over 30 countries compete across three distinct stages: green coffee evaluation, roast profile execution, and production roast blending. Competitors must first assess and grade green coffee samples, identifying defects and predicting flavor potential. They then roast to specified profiles and produce a single-origin production batch judged on roast curve accuracy, development time, and sensory quality. The final blend stage requires competitors to combine multiple roasted coffees into a balanced, harmonious cup. Judges evaluate using the SCA cupping protocol, scoring on aroma, flavor, acidity, body, and balance. The competition has helped standardize roasting terminology and methodology worldwide, elevating roast profiling from artisanal craft to a measurable, data-driven discipline. Past champions including Benoît Cupillard (2022) have advanced roasting science through precision curve analysis and thermal management innovation.
CuppingWorld Cup Tasters Championship
The World Cup Tasters Championship (WCTC) is the premier international competition dedicated to sensory discrimination and palate precision in coffee evaluation, organized annually by the Specialty Coffee Association (SCA) since its inaugural event in 2012. I consider the WCTC the purest test of sensory acuity in the coffee world, where national champions from over 30 countries compete to identify the odd cup out in triangulation cupping sets. Each competition round presents competitors with eight sets of three cups, where two cups contain identical coffee and one is different, requiring participants to identify the unique sample in each set through taste alone. Competitors are scored on both accuracy and speed, with the highest number of correct identifications determining the winner and ties broken by fastest completion time. The triangulation format, rooted in the SCA cupping protocol, tests a taster's ability to detect subtle differences in origin, processing method, roast level, and flavor profile. The competition has helped standardize sensory evaluation methodology worldwide and elevated the professional status of Q-graders and cuppers. Past champions including Daniel Horbat (2022) have demonstrated that elite sensory discrimination requires both innate talent and rigorous, deliberate practice across thousands of tasting repetitions.
Related Concepts
Acidity
In coffee tasting, acidity refers to the bright, vibrant, and often fruity quality that gives coffee its liveliness and structure. Unlike the negative connotation of acidity in everyday language, coffee acidity is a desirable characteristic when balanced. It is perceived as a pleasant tartness or brightness on the palate, similar to the acidity in wine or fruit.
Sensory & TastingAftertaste
Physiological perception of aftertaste is driven by retronasal olfaction, the process wherein volatile organic compounds (VOCs) move from the oral cavity to the olfactory epithelium through the nasopharynx after swallowing. This sensation is distinct from the initial gustatory response to taste buds. Molecular persistence is dictated by the adherence of hydrophobic compounds, such as melanoidins and non-polar lipids, to the oral mucosa. Key chemical contributors include 4-vinylguaiacol, which provides spicy or clove-like notes, and 2-furfurylthiol, responsible for roasted characteristics. The duration and intensity of the finish are measurable via the decay curve of specific aromatic markers. In sensory analysis, this phase is categorized as the 'residual' flavor profile, representing the final stage of the temporal sensory experience. High-quality Arabica typically exhibits a slow decay of sucrose-like sweetness and tartaric acidity, whereas low-quality Robusta often presents a rapid onset of 4-ethylguaiacol, resulting in a persistent medicinal or rubbery finish.
Sensory & TastingBalance
Balance in coffee is the harmonious integration of all flavor attributes (acidity, body, sweetness, bitterness, aroma) so that no single attribute dominates. Balance is a key scoring category on the SCA cupping form.
Sensory & TastingBody
Body, also called mouthfeel, refers to the physical weight, texture, and viscosity of coffee as it is perceived in the mouth. It is a tactile sensation rather than a taste, ranging from thin and tea-like to thick and syrupy. Body is influenced by brewing method, coffee oils, suspended solids, roast level, and the variety and origin of the coffee.
Origins & GeographyCoffea Arabica: The Specialty Coffee Species Explained
Arabica coffee (Coffea arabica) is a species of coffee plant native to the highland forests of Ethiopia and South Sudan. It is the most widely cultivated coffee species worldwide, accounting for approximately 60 to 70 percent of global coffee production. Arabica is prized for its complex flavor, refined acidity, and aromatic diversity, producing notes ranging from floral and citrus to chocolate and caramel depending on origin, variety, and processing.

Varietals & CultivarsSudan Rume Coffee Variety
Sudan Rume is a wild arabica from the Boma Plateau in South Sudan, prized by competition baristas for its explosive tropical fruit and floral aromatics. Nearly extinct in cultivation, it survives in research plots and elite farm lots.
Sensory & TastingSweetness
In physiological terms, sweetness in Coffea arabica is a multi-modal sensory response triggered by a complex matrix of chemical constituents. While green Arabica beans contain between 6% and 9% sucrose by dry weight—compared to 3% to 7% in Coffea canephora —the roasting process degrades approximately 97% to 99% of these sugars. The resulting sweetness perceived by the taster is a product of caramelization and the Maillard reaction. Specifically, the thermal degradation of sucrose yields glucose and fructose, which further react with amino acids to form furans, such as 4-hydroxy-2,5-dimethyl-3(2H)-furanone, contributing to caramel-like aromatics. The SCA Cupping Protocol utilizes a binary score for sweetness; each of the five cups must exhibit a clean, sweet character to receive a 2-point credit, totaling 10 points for a perfect set. This attribute is fundamentally linked to the metabolic health of the tree and precise harvest timing, where cherries typically reach 18% to 22% soluble solids on the Brix scale before picking.
Coffee ScienceTDS (Total Dissolved Solids)
Total Dissolved Solids (TDS) is a measurement of the concentration of dissolved substances in brewed coffee, expressed as a percentage of the total mass. It is the primary metric used to calculate extraction yield and assess brew strength.
Varietals & CultivarsTabi Coffee Variety

Sensory Science and Flavor Perception
Sensory science is the systematic study of how humans perceive food and beverage attributes through their senses. In coffee, sensory science encompasses taste (gustation), smell (olfaction), mouthfeel (tactile), and the complex interactions between them that create the overall flavor experience. Understanding sensory science is essential for coffee professionals, from cuppers evaluating green coffee to baristas dialing in espresso.
Specialty Coffee Association
The Specialty Coffee Association (SCA) is the leading trade association for specialty coffee professionals worldwide, formed in January 2017 by the merger of the Specialty Coffee Association of America (SCAA, founded 1982) and the Specialty Coffee Association of Europe (SCAE, founded 1998). I regard the SCA as the definitive authority on specialty coffee standards, education, and competition, representing more than 30,000 members across 150 countries. The SCA maintains the industry standard definition of specialty coffee: coffee scoring 80 points or above on the SCA Cupping Form, evaluated by certified Q Graders using standardized protocols. The Coffee Skills Program, the SCA's flagship education initiative, offers certifications across five modules: Introduction to Coffee, Barista Skills, Brewing, Green Coffee, and Sensory Skills, with more than 100 Authorized SCA Trainers (ASTs) delivering courses globally. The SCA also organizes the World Coffee Championships, including the World Barista Championship, World Brewers Cup, World Coffee Roasting Championship, World Latte Art Championship, and World Cup Tasters Championship, which collectively draw competitors from over 60 nations. According to SCA market data, the global specialty coffee market was valued at approximately 35 billion USD in 2022 and is projected to exceed 85 billion USD by 2030.

Coffee Grind Size Guide: How Grind Size Affects Extraction, Flow Rate, and Flavor
There is no single universal grind size for coffee. Ground coffee is a distribution of particle sizes rather than one precise particle diameter, and that distribution affects both extraction and flow. Fine, medium, and coarse are starting descriptions, not standardized measurements.
Coffee Extraction Yield: What It Is, How to Calculate It, and What the Numbers Mean
Extraction yield is the percentage of the dry coffee dose dissolved during brewing. This guide explains how it differs from strength and brew ratio, how to calculate it from TDS and beverage mass, and why the 18–22% range is a reference rather than a rule.
How Coffee Extraction Works: Extraction Yield, TDS, and the 18–22% Range
Coffee extraction is a solid–liquid process. This guide explains the difference between extraction yield and TDS, why the 18–22% range is a reference band rather than a rule, and how immersion, percolation, and espresso extraction differ.

Balance
Balance in coffee is the harmonious integration of all flavor attributes (acidity, body, sweetness, bitterness, aroma) so that no single attribute dominates. Balance is a key scoring category on the SCA cupping form.
Body
Body, also called mouthfeel, refers to the physical weight, texture, and viscosity of coffee as it is perceived in the mouth. It is a tactile sensation rather than a taste, ranging from thin and tea-like to thick and syrupy. Body is influenced by brewing method, coffee oils, suspended solids, roast level, and the variety and origin of the coffee.
Acidity
In coffee tasting, acidity refers to the bright, vibrant, and often fruity quality that gives coffee its liveliness and structure. Unlike the negative connotation of acidity in everyday language, coffee acidity is a desirable characteristic when balanced. It is perceived as a pleasant tartness or brightness on the palate, similar to the acidity in wine or fruit.

Coffee Cupping Supplies Guide
Coffee cupping is the standardized global protocol for evaluating green coffee quality, roast uniformity, and flavor attributes. This guide details SCA-certified cupping bowls, silver-plated cupping spoons, sample grinders, and sensory scorecards.
Specialty Coffee
The classification process necessitates precise environment control. During the grading phase, the coffee is roasted within 24 hours of cupping and allowed to rest for at least eight hours. The roast level must fall within the light to medium range, specifically between 55 and 65 on the Agtron scale. Cupping involves a standard ratio of 8.25 grams of coffee per 150 milliliters of water, with water temperatures maintained between 92.2°C and 94.4°C (198°F to 202°F). This protocol ensures that the inherent characteristics of the bean—such as the phosphoric acidity typical of Kenyan origins or the stone fruit notes of Colombian Caturra—are evaluated without the interference of roast-induced flavors.
