🔍

⚡ Crema Espresso

The golden-brown foam that forms on top of a properly extracted espresso shot. It's created by emulsified oils and CO2 from freshly roasted coffee beans.

"A perfect espresso should have a thick, persistent crema that's about 3-4mm thick."

💧 Bloom Brewing

The initial release of CO2 when hot water first contacts freshly ground coffee, causing the grounds to "bloom" or puff up. This is crucial for proper extraction.

"Let the coffee bloom for 30 seconds before continuing your pour-over."

🌱 Terroir Coffee Beans

The environmental factors (soil, climate, altitude) that influence the flavor characteristics of coffee beans from a specific region, similar to wine.

"Ethiopian coffee has a distinct terroir that produces bright, floral notes."

⚖️ Dosing Equipment

The precise measurement of coffee grounds, typically measured in grams. Consistent dosing is essential for reproducible coffee quality.

"I'm dosing 18 grams of coffee for this double espresso shot."

🎯 Tamping Espresso

The process of compressing ground coffee in the portafilter using a tamper to create an even, level surface for water extraction.

"Apply 30 pounds of pressure when tamping to ensure even extraction."

🌊 Channeling Brewing

When water finds the path of least resistance through coffee grounds, creating uneven extraction. This results in sour and bitter flavors in the same cup.

"Uneven tamping can cause channeling, ruining your espresso shot."

🥛 Microfoam Drinks

Steamed milk with tiny, velvety bubbles that create a smooth, glossy texture perfect for latte art. The foam should be barely visible but felt on the palate.

"Perfect microfoam should have the consistency of wet paint."

🔥 First Crack Coffee Beans

An audible popping sound during coffee roasting when moisture inside the beans creates steam and causes them to crack open. Marks the beginning of light roast.

"First crack typically occurs around 385-400°F during roasting."

⏱️ Extraction Time Brewing

The duration water is in contact with coffee grounds. Different brewing methods require different extraction times for optimal flavor balance.

"Espresso extraction time should be 25-30 seconds for a double shot."

🎨 Latte Art Drinks

Decorative patterns created by pouring steamed milk into espresso. Common designs include hearts, rosettas, and tulips, requiring skill and practice.

"She poured a beautiful rosetta pattern in my cappuccino."

🔧 Portafilter Equipment

The handled metal basket that holds ground coffee in an espresso machine. It locks into the group head and comes in single, double, or triple shot sizes.

"Clean your portafilter between shots to prevent bitter flavors."

📅 Degassing Coffee Beans

The natural process where freshly roasted coffee beans release CO2. Beans need 2-14 days to degas for optimal brewing, depending on roast level.

"Let your beans degas for at least 48 hours after roasting."
