What Are the Key Coffee Tasting Terms in Specialty Coffee?

If you’ve ever read a specialty coffee book or taken a barista course, you’ve likely come across a long list of unfamiliar coffee terms—acidity, aroma, body, bitterness, and more. But what do these words actually mean, and why do they matter when describing a cup of coffee? These aren’t just random jargon; they’re the building blocks of how we talk about and understand coffee flavor.

In specialty coffee, there are at least 15 key tasting terms used regularly to describe different aspects of a coffee’s profile. These include acidity, aroma, body, bitterness, and more, each referring to a specific sensory attribute that helps define the coffee’s character.

What Is Acidity in Coffee?

Acidity in coffee refers to a bright, tangy, and vibrant quality often found in high-altitude-grown beans. This is not the same as sourness or pH-level acidity. Instead, it’s a desirable trait that adds liveliness and clarity to the cup, often described as refreshing or wine-like. Acidity contributes to a coffee’s ability to “cleanse” the palate and enhance other flavors.

Understanding Other Core Coffee Tasting Terms

Beyond acidity, several other terms are fundamental to coffee tasting:

• Aroma: The smell of brewed coffee, which can include notes like caramel, chocolate, fruit, or spices. “Bouquet” is a less common term referring specifically to the scent of ground coffee.
• Body: The mouthfeel or weight of coffee on your tongue, ranging from light and watery to thick and syrupy, such as in some Indonesian coffees.
• Bitterness: A basic taste mostly perceived at the back of the tongue, often resulting from dark roasts or over-extraction, not to be confused with acidity.
• Bland: A dull, underwhelming taste often found in low-altitude beans or when coffee is too diluted.
• Briny: A salty sensation caused by over-heating during brewing, sometimes present in poorly brewed shop coffee.

More Flavor & Texture Descriptors in Coffee

The following terms describe additional layers of flavor and texture in specialty coffee:

• Earthy: A soil-like, spicy quality typical of some Indonesian coffees, not to be mistaken for dirty or poorly processed beans.
• Exotic: Unusual, complex aromas reminiscent of flowers, fruits, or spices, often found in East African and Indonesian coffees.
• Flavor: The overall impression of a coffee’s taste, combining aroma, acidity, and body.
• Mellow: Smooth and balanced coffees with low to moderate acidity, often used for Latin American beans.
• Mild: Delicate and refined flavors, typically describing high-quality Latin American coffees excluding Brazil.
• Soft: Low-acid coffees with a gentle, sweet character, such as certain Indonesian beans.

• Sour: A sharp, tart taste common in light roasts, primarily detected at the back of the tongue.
• Spicy: Flavors or aromas reminiscent of spices, such as cardamom, often found in aged or certain high-altitude Indonesian coffees.
• Strong: Often refers to intense flavor or high coffee-to-water ratio, not necessarily high caffeine content.
• Sweet: A pleasant, often fruity or sugary quality that complements wine-like acidity and smooth body.
• Wild: Unpredictable, bold flavors that can be polarizing but also uniquely appealing.
• Winy: A fruity, vinous character with smooth body, exemplified by Kenyan coffees.

Frequently Asked Questions

What does “acidity” mean in specialty coffee?

In specialty coffee, acidity refers to a bright, lively, and refreshing quality often found in high-altitude beans. It is not the same as sourness or pH acidity, but rather a positive trait that adds vibrancy and complexity, often described as wine-like or citrusy.

How is coffee body different from thickness?

Coffee body refers to the tactile feel or weight of the coffee on your tongue. It ranges from light and watery to thick and syrupy. Body is a key part of mouthfeel and helps define the overall texture of the coffee.

What causes bitterness in coffee?

Bitterness is primarily a taste sensed at the back of the tongue and is often caused by dark roasting or over-extraction. It is not the same as acidity and can result from using too much coffee or too little water during brewing.

What does “aroma” refer to in coffee tasting?

Aroma describes the smell of brewed coffee, encompassing a wide range of scents such as caramel, chocolate, fruit, or spices. It is distinct from “bouquet,” which refers specifically to the scent of ground coffee.

What is meant by “wild” coffee flavor?

“Wild” describes coffee with extreme or unconventional flavor profiles that can be polarizing. These flavors may be bold or unusual, and whether they are seen as defects or unique characteristics depends on personal taste.
