por Christopher Worsham

Introduction

Coffee tasting is both an art and a science. Whether you're a seasoned coffee professional or an enthusiastic home brewer, understanding how to taste coffee properly can elevate your appreciation for this complex beverage. In this guide, we’ll explore the sensory evaluation of coffee through cupping, filter brewing, and espresso preparation. We’ll also discuss how to identify and describe tactile sensations, helping you to refine your palate and communicate your impressions with clarity.

The Basics of Coffee Tasting

Before diving into specific brew methods, let’s cover some foundational principles:

  1. Aroma: Begin by smelling the coffee. The aroma provides the first impression and can reveal flavors such as fruits, spices, or chocolate.

  2. Flavor: This is the overall impression of the coffee’s taste, including sweetness, acidity, and bitterness.

  3. Aftertaste: Consider the lingering flavors that remain after swallowing.

  4. Acidity: Not to be confused with sourness, acidity refers to the brightness or liveliness of the coffee.

  5. Body: This is the tactile sensation or weight of the coffee in your mouth, often described as light, medium, or full.

  6. Balance: The harmony between flavor, acidity, and body.

Cupping: The Industry Standard

Cupping is the standard method used by coffee professionals to evaluate coffee. Here’s how to do it properly:

  1. Preparation: Use freshly ground coffee and a consistent coffee-to-water ratio (e.g., 8.25 grams per 150 ml of water). Heat the water to 200°F.

  2. Smell: Start by smelling the dry grounds. After adding water, smell the crust that forms.

  3. Break the Crust: Gently stir the surface after 4 minutes, releasing the coffee’s aroma.

  4. Tasting: Use a cupping spoon to slurp the coffee, aerating it to cover your palate. Focus on flavor, body, and acidity.

  5. Tactile Sensations: In cupping, body is the primary tactile focus. Assess whether the coffee feels syrupy, oily, or thin.

Filter Brewing: Subtle and Nuanced

Filter brewing methods like pour-over and drip machines showcase coffee’s clarity and complexity. To taste filter coffee properly:

  1. Aroma: Smell the coffee immediately after brewing. Filter coffee often reveals floral, fruity, or nutty aromas.

  2. Flavor: Sip the coffee slowly, allowing it to coat your palate. Notice how the flavors evolve as the coffee cools.

  3. Tactile Sensations: Filter coffee typically has a lighter body compared to espresso. Pay attention to its smoothness or silkiness.

  4. Acidity and Balance: Evaluate the brightness of the coffee and how well it integrates with sweetness and bitterness.

Espresso: Intense and Layered

Espresso is a concentrated coffee preparation that demands precision in both brewing and tasting. Here’s how to evaluate it:

  1. Aroma: The crema—the golden layer on top—captures volatile aromas. Smell the espresso immediately after brewing.

  2. Flavor: Take a small sip and let the espresso linger on your tongue. Note the interplay of sweetness, acidity, and bitterness.

  3. Tactile Sensations: Espresso has a dense, velvety body. Describe the texture as creamy, viscous, or heavy.

  4. Aftertaste: Espresso often has a long, lingering aftertaste. Consider whether it’s pleasant or harsh.

Identifying Tactile Sensations

Tactile sensations—or mouthfeel—refer to the physical attributes of the coffee in your mouth. Here’s how to assess them in each brew method:

  1. Cupping: Focus on body. A coffee with a high body may feel thick or syrupy, while a low-body coffee feels thin and watery.

  2. Filter Brewing: Look for descriptors like smooth, silky, or tea-like. The body is usually lighter but still nuanced.

  3. Espresso: Notice the texture of the crema and the overall density. Is it creamy or astringent?

How to Describe Coffee Tactilely

Describing tactile sensations requires a precise vocabulary. Here are some terms to use:

  1. Light Body: Tea-like, delicate, thin.

  2. Medium Body: Balanced, smooth, round.

  3. Full Body: Syrupy, creamy, heavy.

  4. Texture: Silky, gritty, velvety, astringent.

Tips for Refining Your Palate

  1. Taste Regularly: Consistent practice is key to developing your palate.

  2. Taste Blind: Remove biases by evaluating coffee without knowing its origin or roast profile.

  3. Keep Notes: Record your impressions to track your progress and preferences.

  4. Use Reference Points: Compare coffee flavors to familiar foods like fruits, nuts, or spices.

Conclusion

Tasting coffee is a journey of discovery. By learning to evaluate coffee through cupping, filter brewing, and espresso, and by focusing on both flavor and tactile sensations, you can deepen your appreciation for this remarkable beverage. Practice regularly, refine your vocabulary, and don’t be afraid to experiment—the world of coffee has endless surprises waiting for you.
