Technical Glossary

The return on investment from a managed coffee program, calculated by balancing equipment costs, bean quality, labor efficiency, and revenue from beverage sales.

A numerical rating from 0-100 assigned by certified Q Graders based on aroma, flavor, aftertaste, acidity, body, balance, and other attributes of a coffee sample.

The specific time-temperature curve used during roasting that determines the bean's flavor, aroma, body, and acidity, tailored to achieve desired taste characteristics.

The sequence of tasks from order taking to beverage delivery, designed for efficiency, speed, and quality in a commercial coffee environment.

The percentage of coffee bean mass that dissolves into water during brewing, typically ranging from 18-22% for optimal flavor extraction in specialty coffee.

The practice of openly sharing information about coffee origin, farmer relationships, and supply chain practices to build trust and quality assurance.

A recurring delivery service for coffee beans, often with flexible scheduling and roast profiles, ensuring fresh supply and predictable costs for businesses.

The practice of openly sharing information about coffee sourcing, including origin, farmer relationships, pricing, and processing methods, to build trust and sustainability.

Strategies to minimize and repurpose coffee byproducts like spent grounds and chaff, including composting, biogas generation, or upcycling into products like body scrubs.

The total waste generated from coffee preparation, including spent grounds, packaging, and water, which can be minimized through efficient practices and recycling.

Strategies to maximize the amount of usable coffee extracted from beans, reducing waste and improving profitability without sacrificing quality.

A sourcing model where roasters buy directly from producers, bypassing intermediaries, to ensure higher payments to farmers and greater control over quality and sustainability.

A full-cycle service covering consultation, equipment selection, installation, training, ongoing supply, maintenance, and support for all coffee and related beverages.

The percentage of coffee solubles extracted from ground coffee during brewing, typically ranging from 18% to 22% for optimal flavor balance, measured using a refractometer.

A technique in espresso brewing that varies water flow rate during extraction to highlight specific flavor notes, achieved through programmable or manual valve adjustments.

The specific particle size distribution of coffee grounds, tailored to a brewing method, affecting extraction rate and flavor; adjusted via burr grinder settings.

A comprehensive service where a provider supplies, maintains, and manages all coffee equipment and supplies for a business, ensuring consistent quality and minimal operational burden.

A controlled, low-pressure wetting of coffee grounds before full extraction, allowing gases to escape and ensuring even saturation for a more balanced espresso shot.

The deliberate adjustment of water pressure during espresso extraction to influence flavor, often using programmable pumps to create a pressure curve over time.

A planned calendar of regular inspections, cleaning, and part replacements for coffee equipment to prevent breakdowns and ensure optimal performance.

Coffee sourced from one geographic region, farm, or cooperative, offering distinct flavor profiles that reflect terroir, processing, and varietal characteristics.

High-end, precision-engineered machines and grinders designed to produce superior coffee, often featuring advanced temperature control, pressure profiling, and consistent extraction.

The method of positioning and aerating milk with an espresso machine's steam wand to create microfoam for latte art and optimal texture, requiring precise angle and depth control.

A movement emphasizing coffee as an artisanal product, focusing on origin, traceability, and craft preparation, similar to wine or craft beer appreciation.
