Common Coffee Terms Every Specialty Coffee Drinker Should Know

If you’ve ever wondered what professionals mean by 'cupping' or why 'bloom' matters when brewing pour-over, you’re not alone. Specialty coffee has its own language, and understanding these terms helps you make better coffee and talk shop with confidence.

Here’s a clear breakdown of 12 common coffee terms every coffee enthusiast should know—from cupping and extraction to espresso crema and barista lingo—explained with the exact details you need.

What Is Coffee Cupping and How Is It Done?

Cupping is a standard method for evaluating coffee quality. It involves placing freshly ground coffee in a cup, pouring hot water over it, and letting it steep.

Key Coffee Brewing and Chemistry Terms Explained

Extraction: This is the process of dissolving soluble compounds from coffee grounds using water. Proper extraction is key to balancing sweetness, acidity, and bitterness in your brew.
Oxidation: A chemical reaction where substances combine with oxygen, leading to changes in flavor and freshness—this is why coffee stales over time.
Maillard Reaction (also called in Chinese): A complex series of chemical reactions during coffee roasting that develops flavors and colors, often mistakenly referred to as caramelization. Though the term '' is used, it is not the same as simple sugar caramelization and does not involve burning.

Espresso and Milk Drink Essentials

Crema: The golden-brown foam that forms on top of a well-pulled espresso shot. It’s a sign of quality and contributes to the espresso’s texture and aroma.

Bloom (bloom): In pour-over brewing, blooming refers to the initial pour of hot water over coffee grounds to release trapped gases. This step pauses the water flow briefly to improve extraction and enhance flavor.
