The Specialty Coffee Association (SCA, Brewing Standards) defines extraction yield 18-22% and TDS 1.15-1.35% as the Gold Cup target for filter; espresso targets vary by recipe. Hold dose constant (e.g., 18g), then adjust grind finer for faster shots or coarser for slower. Log one variable change at a time across consecutive rows. After 10-15 entries, the links between grind, time, and flavor become clear — the same method Q Grader training (Coffee Quality Institute) formalizes.

Yes. The SCA Coffee Taster's Flavor Wheel (2016, revised with World Coffee Research Sensory Lexicon) gives you a shared vocabulary that moves from broad categories (fruity, nutty, floral) to specific descriptors (blackberry, almond, jasmine). Start broad on early entries, then get specific as your palate develops. Q Grader cupping protocols require descriptors from this lexicon. Pair flavor notes with the acidity and body fields — together they form the core sensory dimensions of the SCA cupping form.

The SCA cupping form rates each attribute on a 6-10 scale; 6 = good, 7 = very good, 8 = excellent, 9-10 = outstanding. For acidity, separate quality (bright vs. sharp) from intensity. Body refers to mouthfeel weight, not flavor strength. Keep your overall score within one point of the average of the attributes — outliers usually signal halo bias. Q Grader training stresses calibration through repeated reference samples.

Origin and roast interact but are independent variables. World Coffee Research's Arabica Variety Atlas documents that the same variety from Ethiopia or Colombia shows distinct flavor lineage, while roast level dictates how much of that origin character survives. Light roasts preserve origin acidity; dark roasts shift flavors toward roast-driven notes. Tracking both lets you separate 'I like Ethiopia' from 'I like light roasts' — a distinction most casual drinkers blur together.

SCA Brewing Standards specify 93-96°C (200-205°F) for the best extraction of filter coffee. Lower temperatures underextract — sour, weak; higher temperatures risk bitterness. Research in Food Research International (e.g., studies on brewing temperature and extraction yield) confirms temperature drives extraction kinetics alongside grind and contact time. If you brew below 90°C, expect dialing-in to push toward finer grinds or longer times. Record the actual temperature, not the kettle setting if they differ.

Apps automate timers and recipe storage but pull your attention away from the cup. Paper requires deliberate observation, which Q Grader sensory training (CQI) treats as the foundational skill — instruments cannot replace calibrated tasting. Ten rows per page also let you compare consecutive brews side by side, which is harder to scan on small screens. Use the app for stopwatch precision if you like, but record your sensory data here for focused reflection.

World Coffee Research and SCA educators broadly suggest 30-50 deliberate cuppings before patterns emerge — preferred origins, roast levels, brew methods. Hold one variable constant per week (e.g., same beans, varying grind) to isolate its effect. Review the rating column monthly: do your 8+ scores cluster on Ethiopia naturals, Colombian washed, or specific roasters? The table format makes this longer-term scan possible — your own palate becomes the database.

First, changing multiple variables between brews — you lose isolation. Second, rating without smelling first; aroma drives 70-80% of flavor perception (basic olfaction research summarized in Food Chemistry literature). Third, ignoring water mineral content, which the SCA Water Quality Handbook (2009) shows materially affects extraction. Fourth, vague flavor notes — 'nutty' is less useful than 'almond, milk chocolate.' Finally, scoring before the cup cools; many flavors only emerge below 60°C.
