For those who measure their coffee in grams and track temperatures to the tenth of a degree, this is your blueprint. Your setup—Weber EG-1 with ultra-low fines burrs, Decent DE1 with pressure profiling, and a symphony of calibrated tools—hints at a pursuit beyond casual brewing. Yet, the real magic lies in the invisible calculus of water chemistry, bean selection, and timing. Let’s dissect what makes your method tick and where it might tweak.
Your water protocol is a masterclass in balance. Starting with reverse osmosis and remineralizing to 90 ppm TDS, 50 ppm GH, and 35 ppm KH sets a foundation that amplifies acidity and floral notes in Geisha. Magnesium-forward water isn’t just a tweak—it’s a revelation. But precision here demands consistency: temperature stability within ±0.2°C and a mineral solution tailored to bean density. This isn’t guesswork; it’s science calibrated for taste.
The bean protocol is equally deliberate. Panama Geisha, whether from Finca Elida or a COE-winning anaerobic lot, requires light roasts and a 10–18 day rest. Storage in vacuum-sealed, frozen conditions ensures freshness, while grinding directly from frozen locks in aroma. The VST basket and blind shaker ensure even distribution, but the real trick is in the extraction profile. Your 1:2.3 ratio and 28–34 second window demand a balance of pressure and flow, with the DE1’s profiling capabilities as your compass.
Yet, even the most meticulous setup needs calibration. Weekly cupping to test 20%, 21.5%, and 23% yields reveals your sweet spot. Adjustments for bitterness, sourness, or hollow shots are not just fixes—they’re refinements. Tracking dissolved oxygen, room humidity, and degassing schedules turns your routine into a ritual.
Dosing and distribution hinge on precision—every 0.
Key points: Your water chemistry is the backbone of flavor, so prioritize TDS, GH, and KH ratios. Dosing and distribution hinge on precision—every 0.05g matters. Extraction profiling isn’t about speed but balance, with pressure and flow as your levers.
