Introduction to Coffee Cupping
What is Coffee Cupping?
Coffee cupping, often simply referred to as “cupping,” is the industry-standard method for evaluating and scoring the quality of coffee beans. It’s a systematic tasting technique used by professionals such as green coffee buyers, roasters, and baristas to assess a coffee’s flavor profile, aroma, body, acidity, and overall balance. The process involves deeply sniffing the coffee, then loudly slurping the coffee so it spreads to the back of the tongue. This practice allows the cupper to understand the nuances of the coffee, from its first aromatic impression to its final aftertaste.
The History and Significance of Cupping
The origins of coffee cupping can be traced back to the coffee houses of the Ottoman Empire, where the quality and characteristics of coffee were first scrutinized and debated. Over the centuries, cupping has evolved into a more formalized and critical process, becoming a cornerstone in the coffee industry for ensuring quality and consistency. The significance of cupping lies in its ability to provide a common language and set of standards for coffee professionals around the globe.
The Role of Cupping in the Coffee Industry
Cupping plays a pivotal role in the coffee industry, serving as a vital tool for quality control, product development, and education. It is used to test the quality and consistency of coffee samples, identify any defects, and ensure that only the highest quality beans reach consumers. Roasters rely on cupping to perfect their roast profiles, while baristas use it to expand their palates and knowledge of coffee origins. The Specialty Coffee Association (SCA) has established cupping protocols to standardize the process, fostering a fair and transparent global coffee market.
Understanding the Cupping Process
The cupping process begins with the examination of coffee beans and grounds, assessing their size, shape, and color for clues about origin and roast level. Next, hot water is poured over the grounds, and the coffee is left to steep, forming a crust. After a few minutes, the crust is broken with a spoon, releasing a burst of aromas for evaluation. The coffee is then tasted, with the cupper slurping it to aspirate the coffee over the entire palate. This helps to identify the coffee’s sweetness, acidity, flavor, aftertaste, and body. Finally, the coffee is scored on these attributes, with each coffee receiving a score that reflects its quality.
Preparing for a Cupping Session
Selecting the Right Environment
Before diving into the sensory world of coffee cupping, it’s essential to select an environment conducive to focus and analysis. The ideal cupping space should be well-lit and quiet, free from any interfering aromas that could skew the perception of the coffee’s natural scents. A comfortable temperature is also key, as it ensures the taster’s senses are not numbed by cold or overwhelmed by heat.
Essential Tools for Cupping
Having the right tools is crucial for a successful cupping session. The essentials include:
- Cupping glasses with lids: These should be of tempered glass or ceramic material, with a capacity of 7 to 9 fluid ounces and a top diameter of 3 to 3.5 inches.
- Cupping spoons: Designed with a deep bowl to facilitate slurping and tasting.
- Grinder: A quality grinder that can produce a consistent grind slightly coarser than that used for paper filter drip brewing.
- Balance (Scale): To precisely measure coffee and water ratios.
- Hot water equipment: To ensure water is at the correct temperature for brewing.
- Forms and other paperwork for note-taking and scoring.
Choosing and Roasting Coffee Beans
When selecting coffee beans for cupping, diversity is key. Choose beans from various origins and processing methods to understand a wide range of flavor profiles. The beans should be roasted within 24 hours of cupping and allowed to rest for at least 8 hours. The roast level should be measured using an Agtron or similar color reading device to ensure consistency across samples.
Grinding Coffee for Cupping
The grind is a pivotal factor in cupping. Coffee should be ground immediately prior to cupping, no more than 15 minutes before infusion with water. The grind particle size should be slightly coarser than typically used for paper filter drip brewing, with 70% to 75% of the particles passing through a U.S. Standard size 20 mesh sieve. At least 5 cups from each sample should be prepared to evaluate sample uniformity, ensuring a consistent and fair assessment of each coffee’s qualities.
The Cupping Protocol
The SCA Cupping Guidelines
The Specialty Coffee Association (SCA) has established a set of guidelines to standardize the cupping process, ensuring consistency and accuracy in coffee evaluation. These guidelines cover every aspect of cupping, from the preparation of the coffee to the scoring of its attributes. Adhering to these protocols allows cuppers from around the world to assess coffee in a uniform manner, creating a common language for discussing coffee quality.
Water Quality and Temperature
Water is a critical component in cupping, as it directly affects the extraction and flavor of the coffee. The SCA recommends using clean, odor-free water that is not distilled or softened. The ideal Total Dissolved Solids (TDS) range is between 125-175 ppm, ensuring the water is neither too mineral-rich nor too pure. The temperature of the water should be approximately 200º F (93ºC) at the time of pouring, with adjustments made for elevation to maintain the correct extraction rate.
Coffee-to-Water Ratios
The coffee-to-water ratio is essential for achieving the optimal balance of flavors. The SCA’s golden ratio is 8.25 grams of coffee per 150 ml of water. This ratio ensures that the coffee’s strength and extraction levels are within the ideal range for sensory evaluation. Cuppers must weigh the coffee beans accurately and adjust the weight to the specific volume of their cupping vessel to maintain this ratio.
Infusion Time
After pouring hot water onto the ground coffee, the mixture should steep undisturbed for a period of 3-5 minutes. This infusion time allows for proper extraction of the coffee’s soluble compounds, which contribute to its flavor and aroma. The exact time may vary slightly depending on the coffee’s grind size and density, but it should remain within the specified range to ensure consistency across all samples.
Breaking the Crust and Cleaning the Cups
Once the infusion time has elapsed, cuppers break the crust formed by the coffee grounds floating on the surface. This is done by gently stirring the coffee three times, allowing the grounds to settle and releasing the coffee’s full aroma. After breaking the crust, any remaining grounds on the surface are carefully skimmed off with a spoon. This step is crucial for preventing grounds from interfering with the tasting and ensuring a clear evaluation of the coffee’s flavor.
By meticulously following the SCA cupping protocol, cuppers can accurately assess the quality of coffee. This process involves precise measurements, strict timing, and a keen sensory awareness, all of which contribute to the cupper’s ability to identify and describe the complex characteristics of each coffee sample.
Sensory Evaluation Techniques
Aroma Assessment
The first step in sensory evaluation during coffee cupping is assessing the aroma. Aroma is a critical component as it can reveal a lot about a coffee’s character and quality. To properly evaluate the aroma, gently sniff the coffee grounds before and after adding water. Initially, you’ll encounter the ‘dry fragrance,’ which is the smell of the ground coffee. After adding hot water, you’ll experience the ‘wet aroma’ as the heat releases volatile compounds. Take note of the intensity, quality, and the different scents that you can identify, ranging from floral and fruity to spicy and earthy.
Slurping: Tasting for Flavor and Body
Slurping is a unique tasting technique used to assess the flavor and body of coffee. By taking a spoonful of coffee and slurping it vigorously into your mouth, you aerate the coffee, spreading it across your palate. This action helps to perceive the full range of flavors and the body or mouthfeel of the coffee. Pay attention to the weight and texture as it can range from tea-like and light to creamy and full-bodied.
Identifying Acidity, Sweetness, and Bitterness
Acidity, sweetness, and bitterness are fundamental taste attributes in coffee. Acidity should be distinguished from sourness; it provides a pleasant sharpness and can be reminiscent of citrus or berries. Sweetness is an indicator of a well-developed coffee and can manifest as sugary, fruity, or syrupy notes. Bitterness, when balanced, adds depth and complexity but should not be overwhelming. Evaluate these components for their presence and harmony within the cup.
Aftertaste and Balance
The aftertaste, or finish, is the taste left on the palate after swallowing the coffee. It can be lingering and complex, revealing flavors that were not immediately apparent. A good aftertaste is one that is pleasant and resonates with the initial flavor profile. Balance is the overall harmony between acidity, sweetness, bitterness, and body. A balanced coffee will not have one attribute overpowering the others, but rather a cohesive interplay that enhances the drinking experience.
Using a Flavor Wheel
The Coffee Taster’s Flavor Wheel is an invaluable tool for identifying and articulating the flavors and aromas found in coffee. It provides a comprehensive lexicon of coffee tastes and aromas, organized from the center of the wheel (which includes the most general descriptors) to the outer edge (which includes the most specific descriptors). As you taste, refer to the wheel to help pinpoint specific flavors and to expand your descriptive vocabulary. This practice not only aids in assessment but also in communicating your sensory experience to others.
Scoring and Describing Coffee
The Coffee Scoring System
The coffee scoring system is a standardized method used by professionals to evaluate and communicate the quality of coffee. It involves assessing various attributes of the coffee, such as aroma, flavor, aftertaste, acidity, body, balance, and overall impression. Scores are typically given on a scale of 0 to 100, with higher scores indicating superior quality. Specialty coffees often score above 80 points. This system allows for a consistent and objective way to compare different coffees and is essential for anyone looking to assess coffee like an expert.
Descriptive Language in Cupping
Mastering the descriptive language in coffee cupping is crucial for articulating the complex sensory experience of tasting coffee. Cuppers use a wide range of terms to describe the sensory attributes they detect, from the coffee’s fragrance and aroma to its flavor profile and mouthfeel. This language enables cuppers to communicate their findings clearly and effectively, providing a detailed account of a coffee’s characteristics.
Common Coffee Tasting Terms
- Fragrance: The smell of dry coffee grounds.

Beyond Cupping: Understanding Coffee Quality
The Impact of Origin and Terroir
The quality and flavor profile of coffee are profoundly influenced by its origin and terroir. Terroir, a term borrowed from the wine industry, refers to the unique combination of factors including soil, climate, altitude, and farming practices that give coffee from a particular region its distinctive taste. For instance, Ethiopian coffees are often noted for their floral and fruity characteristics, while those from Colombia may exhibit a balanced sweetness and nutty notes. Understanding the terroir helps experts predict flavor profiles before cupping, although the actual tasting is essential for an accurate assessment.
Processing Methods and Their Effects
Coffee beans undergo various processing methods post-harvest, which significantly affect their final taste. The three primary methods are natural (dry), washed (wet), and honey (semi-washed). Natural processing often imparts a heavier body and sweeter, more complex flavors, as the bean dries in the fruit. Washed coffees tend to have a cleaner taste and higher acidity, reflecting the bean’s intrinsic qualities. Honey processing falls somewhere in between, offering a balance of sweet and acidic notes. Recognizing the nuances these methods introduce is crucial for a comprehensive quality assessment.
Sustainability and Ethical Sourcing
As consumers become more conscious of their purchases, sustainability and ethical sourcing have become integral to the coffee industry’s discourse. Sustainable practices ensure the long-term health of coffee farms, while ethical sourcing emphasizes fair compensation and working conditions for farmers. These factors not only affect the moral and environmental aspects of coffee production but can also influence the quality of the beans. Ethically sourced coffees often come from farms that invest more in quality control and sustainable agriculture, leading to a superior product.
The Future of Coffee Cupping
The practice of cupping is evolving with technology and a growing emphasis on transparency and education. Innovations like digital flavor wheels and cupping apps are making it easier to record and share tasting notes, fostering a more connected global coffee community. Additionally, there is a trend towards standardizing cupping protocols to ensure consistency across the industry.
