Coffee terms starting with R

9 coffee terms starting with R, each with its definition and its German and Turkish names.

Term	German	Turkish	Definition	Category
Rancid	Ranzig	Ekşimiş	A severe sensory defect describing the sharp, unpleasant chemical odor and taste of spoiled, oxidized lipids in stale or improperly stored coffee beans. In professional coffee cupping, this term is strictly reserved for genuine lipid deterioration and must not be used loosely to describe other strong or heavy aromas unless clear signs of physical and chemical degradation are present.	Sensory
Red Eye	Red Eye	Red Eye	A standard cup of drip-brewed filter coffee boosted with a single shot of espresso. Originating in American coffee culture, this beverage is designed to provide an extra kick of caffeine and a richer body, popular among commuters and those needing a stronger energy boost.	Beverage
Reposo	Reposo	Reposo	The Spanish term for "resting," referring to the critical post-drying stabilization period—typically lasting 30 to 60 days—during which processed parchment coffee is left undisturbed in storage. This resting phase allows the internal moisture within the green coffee beans to equalize and stabilize, enhancing the longevity of the coffee's flavor profile, freshness, and structural integrity prior to hulling, export, and roasting.	Processing
Retention	Retention	Kalıntı	In coffee grinding, retention refers to the amount of ground coffee—both fresh and stale—that remains trapped inside the grinder's burr chamber, chute, and pathways after a grinding cycle is completed. It is a critical factor in cafe workflows and single-dosing, as high retention can lead to flavor contamination from stale grounds mixing with freshly ground coffee.	General
Rio	Rio	Rio	A traditional classification for dry-processed Brazilian coffees characterized by a distinct, pungent medicinal or iodine-like flavor caused by microbial invasion during the drying process. While considered a severe sensory defect by specialty and North American buyers, this specific flavor profile—often referred to as "Rioy"—is historically sought after and preferred by certain markets in the Balkans and the Middle East.	Green Coffee
Ristretto	Ristretto	Ristretto	A shorter, highly concentrated espresso extraction brewed with the same amount of coffee grounds as a standard espresso but significantly less water—typically achieved by stopping the extraction early. This results in a smaller, bolder cup with reduced bitterness, heightened sweetness, and a thicker, syrupy body.	Beverage
Roast	Röstung	Kavurmak	The thermal processing method in which unpalatable green coffee beans are subjected to controlled heat to trigger complex chemical reactions—such as the Maillard reaction, caramelization, and pyrolysis—transforming their internal precursors into the volatile aromatic compounds, oils, and complex flavor profiles that are extracted during brewing.	Roasting
Robusta	Robusta	Robusta	A major commercial coffee species (Coffea canephora) characterized by low-altitude cultivation, high crop yield, strong disease and pest resistance (particularly against coffee leaf rust), and a high caffeine content, nearly double that of Arabica. Robusta beans typically yield a full-bodied, heavy crema with a distinct earthy, bitter, and sometimes rubbery flavor profile, making them a standard ingredient in commercial espresso blends, instant coffee, and low-cost formulations.	Botany
Rubbery	Gummiartig	Kauçuksu	A distinct sensory descriptor characterizing the aroma and flavor reminiscent of hot tires, rubber bands, or vulcanized rubber. While generally considered an undesirable taint or defect in specialty Arabica coffees, a rubbery characteristic is common, highly recognizable, and often accepted as a standard regional trait in certain commercial origins, particularly in fresh or low-altitude Robustas (Coffea canephora).
