About
I analyze gooseneck shapes, flow curves, and thermal drift during pours to help serious brewers and cafes hit target extractions.
Core Beliefs
Extraction is constrained by controllable physics; respect them, and flavor opens up.
Background
In a crowded cupping lab, I weighed a bloom while timing the pour and noticed extraction drifting across identical brews. A borescope later revealed a burr inside the gooseneck changing flow. That day I started measuring flow rate, not just temperatures, because the cup had already told me.
Perspective
I favor kettles with consistent flow and minimal thermal drift under motion.

Best Stainless Steel Kettle vs Glass: Stop Plastic Taste Now
Learn how kettle material drives flavor and extraction - and why fully metal 304/316 stainless steel pathways outperform glass by minimizing plastic off-flavors and holding pour temperatures steady. Get clear criteria to avoid hidden plastics and choose a kettle that delivers repeatable, clean-tasting brews.
Travel Kettle Comparison: Dual Voltage Portables Tested
A data-driven breakdown of dual-voltage travel kettles shows how voltage stability, heat loss, and flow control affect brew quality, and which safety and material features to prioritize. It highlights techniques and designs that maintain consistency on the road, with 0.5L stainless models with flat heating elements proving the most reliable.
