Coffee Glossary: Bean and Origin Terms

Arabica: The world's most widely grown coffee species. It produces a smoother, more complex cup than Robusta and is commonly found in premium coffee.

Robusta: Higher in caffeine and bolder in flavor than Arabica. It is often used in espresso blends for extra body and crema.

Cherry: Coffee beans are the seeds inside a coffee cherry. After harvesting and processing, the seeds are roasted to make coffee.

Single Origin: Coffee sourced from one country, region, or farm. It highlights regional flavors. Browse Blackout's premium coffee lineup for current offerings.

Estate-Grown: Coffee produced entirely on one farm or estate, offering greater traceability from harvest to cup.

Roasting Terms

Green Coffee: Raw, unroasted coffee beans. Roasting develops the flavors found in your cup.

First Crack: The first audible cracking sound during roasting. It marks the beginning of a light roast.

Second Crack: A second round of cracking that signals a darker roast with bolder flavor and lower acidity. Learn what makes a great dark roast taste bold.

Degassing: Freshly roasted beans release carbon dioxide for several days. Waiting 24 to 48 hours before brewing helps improve extraction.

Bloom: The bubbling that occurs when hot water first contacts fresh coffee grounds. A strong bloom usually indicates fresh beans.

Brewing Methods

This Coffee Glossary includes the brewing methods most coffee drinkers use every day.

Pour-Over: Hot water flows slowly through coffee grounds in a filter. It produces a clean, bright cup.

Chemex: A glass pour-over brewer with a thick paper filter that creates a clean, smooth cup with little sediment.

French Press: A full-immersion brewer that steeps coarse grounds. A mesh filter creates a rich, full-bodied cup.

Cold Brew: Coffee steeped in cold water for 12 to 24 hours. It produces a smooth, low-acid concentrate.

Espresso: Hot water is forced through finely ground coffee under high pressure to create a concentrated shot with crema.

Moka Pot: A stovetop brewer that uses steam pressure to produce bold coffee. Want similar intensity? Try Blackout's Instant Coffee.

Equipment Terms

This section explains the essential tools used for brewing and espresso preparation.

Burr Grinder: A grinder that crushes beans with burrs instead of blades for a more consistent grind and better extraction.

Pour-Over Kettle: A gooseneck kettle designed for slow, precise pouring and better brewing control.

Portafilter: The handled basket that holds ground coffee during espresso extraction.

Tamper: A tool used to compress ground coffee evenly before brewing espresso for consistent extraction.

Flavor and Extraction Terms

This Coffee Glossary explains the flavor and extraction terms that help describe every cup.

Crema: The golden foam on top of a properly brewed espresso. It is a sign of fresh beans and proper extraction.

Extraction: The process of dissolving flavor from coffee into water. Under-extraction tastes sour, while over-extraction tastes bitter.

Body: The weight and texture of coffee in your mouth. It can range from light and tea-like to rich and syrupy.

Acidity: The bright, lively quality that adds balance and complexity to coffee without making it taste sour.
