Coffee Beans & Origins
Arabica: High-quality coffee species grown at high altitudes, known for complex flavors and less caffeine than Robusta
Robusta: Coffee species with higher caffeine content, more disease resistance, and stronger, often more bitter flavor
Single Origin: Coffee sourced from one specific geographic region, farm, or producer
Blend: Combination of beans from different origins to create a specific flavor profile
Peaberry: Natural mutation where the coffee cherry produces a single, more rounded bean instead of two flat-sided beans
Estate Coffee: Coffee grown on a single farm or plantation
Micro-lot: Small, specially separated portion of a farm with unique characteristics
Green Coffee: Unroasted coffee beans that have been processed and dried but not yet roasted
Specialty Coffee: High-quality coffee scoring 80+ points on a 100-point scale by certified coffee tasters
Varietal: Specific genetic subtype of coffee plant (e.g., Bourbon, Typica, Gesha/Geisha, Caturra)
Terroir: Environmental factors affecting crop's qualities, including soil, climate, and altitude
Coffee Processing Methods
Washed/Wet Process: Method where fruit is removed before beans are dried, resulting in cleaner, brighter flavors
Natural/Dry Process: Beans dried inside the coffee cherry, producing fruitier, sweeter flavor profiles
Honey/Pulped Natural Process: Partial removal of fruit before drying, resulting in characteristics between washed and natural
Semi-washed: Process where some mucilage remains on the bean during drying
Anaerobic Fermentation: Fermentation in oxygen-free environment to develop unique flavor characteristics
Monsooned: Beans exposed to monsoon winds to reduce acidity and create a distinctive flavor
Aged Coffee: Deliberately aged green coffee beans to develop unique flavors
Carbonic Maceration: Wine-inspired processing method using carbon dioxide to create fruit-forward profilesWrite your text here...
Roasting Terms
Roast Profile: Time and temperature pattern used to roast coffee
First Crack: Audible popping sound during roasting when beans expand and moisture escapes
Second Crack: Later cracking sound indicating more developed roast with oils surfacing
Light Roast: Roasted to just before or at first crack, preserving origin characteristics
Medium Roast: Roasted to between first and second crack, balancing origin and roast flavors
Dark Roast: Roasted to or beyond second crack, emphasizing roast character over origin
City Roast: Medium roast completed shortly after first crack
Full City Roast: Medium-dark roast approaching second crack
French Roast: Very dark roast with oils on surface and strong roast flavor
Italian Roast: Extremely dark roast with pronounced bitterness
Development Time: Period from first crack to end of roast
Roast Date: When beans were roasted, important for freshness
Degassing: Release of carbon dioxide from freshly roasted beans
Quenching: Rapidly cooling beans to stop the roasting process
