Complete Manual Brewing Suite | AeroPress® Original + 2x 250g Single Origins + Dial-In Matrix
Eliminate the variables. Master extraction from day one.
Great coffee is not an accident of intuition; it is an equation of fluid dynamics, temperature, grind distribution, and contact time. The Extraction Calibration Kit is engineered to eliminate trial-and-error by closing the loop between hardware, green bean chemistry, and brewing technique.
By combining the world's most thermally stable, forgiving immersion brewer with two contrasting seasonal single origins and our laboratory-tested recipe cards, this kit guarantees clean, repeatable, zero-defect extraction right out of the box.
What’s Included in the Suite
-
1x AeroPress® Original Chamber, Plunger & Seal
Constructed from durable, BPA-free, shatterproof copolyester. Its hybrid immersion-and-pressure extraction delivers uniform saturation with zero bypass, producing high clarity and rich mouthfeel.
-
1x Pack of 350 Official AeroPress Micro-Filters
Medical-grade paper filters engineered to capture micro-fines and unwanted bitter oils while allowing aromatic solubles to pass cleanly into the decanter.
-
2x 250g Seasonal Single Origins (The Trajectory Series)
Two distinct, high-elevation single-origin coffees roasted on our all-electric, fluid-bed system. Zero combustion, zero surface scorching, and absolute internal core development ensure every particle extracts at an even rate.
-
1x Calibration Guide
Reference card detailing exact gram doses, grind micrometer settings, water temperatures, and timed plunge phases for both coffees.
Why This Pairing Works: The Science of Clean Extraction
Most beginner pour-over setups fail because hand-pouring introduces unstable flow rates, temperature drop, and uneven channeling through the coffee bed.
The Extraction Calibration Kit solves this through three controlled physical principles:
-
Total Immersion (Uniform Saturation): Coffee grounds are fully suspended in water, guaranteeing that every particle begins extracting at the exact same fraction of a second.
-
Zero-Combustion Roast Uniformity: Because our beans are roasted purely via convective fluid-bed airflow, the cell structure of the bean develops identically from core to surface. When ground, the coffee produces a tighter particle size distribution with fewer extraction-muddying "fines."
-
Low-Pressure Filtration: Gentle pneumatic pressure forces brew water through the bed in under 30 seconds, preventing the over-extraction of bitter, astringent chlorogenic acids common in conventional drip machines.
