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.

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. Pair flavor notes with the acidity and body fields — both are attributes scored on 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. The same variety grown in Ethiopia or Colombia can taste distinctly different, 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 guidelines put the water for filter coffee at roughly 92-96°C (about 198-205°F). Lower temperatures underextract — sour, weak; higher temperatures risk bitterness. Temperature works together with grind and contact time to drive extraction, so changing one usually means adjusting another. 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.

There is no fixed number, but patterns usually start to show after a few dozen deliberate entries — 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; much of what we perceive as flavor actually comes from smell. Third, ignoring water mineral content, which the SCA's water quality standard treats as a major factor in extraction and taste. Fourth, vague flavor notes — 'nutty' is less useful than 'almond, milk chocolate.' Finally, scoring before the cup cools; many flavors only emerge as it cools down.
