Gongfu at High Altitude: How Lower Boiling Points Change Tea Chemistry

Gongfu at High Altitude: How Lower Boiling Points Change Tea Chemistry

⏱ 1 min read The Short Version Brewing tea at high altitude, where water boils at 92°C instead of 100°C, alters tea chemistry, challenging Gongfu techniques by reducing extraction and shifting flavor dynamics. Adjusting steeping time or leaf ratios can still yield depth, but the science of tea chemistry changes at altitude. In This Article The Science of Boiling Points at AltitudeGongfu’s Threshold: Extraction Beyond the Boil If you’ve ever brewed tea at altitude, you’ve probably noticed that water doesn’t behave as expected. At 2000 meters, it boils at 92°C—far from the 100°C you’re used to. This isn’t just an…

Bambino Plus Can’t Hit 1:2 Ratio—Here’s Why

Bambino Plus Can’t Hit 1:2 Ratio—Here’s Why

⏱ 1 min read The Short Version The Bambino Plus reveals a mismatch between grind settings and extraction dynamics, showing that even precise dosing can’t fix a too-coarse grind or a fixed portafilter’s limitations. In This Article Grind Settings & Machine LimitationsExtraction Speed & Dose Adjustments You’re grinding at 8, dosing 18g, and pulling shots in 24 seconds—but the math still doesn’t align. This is the core tension of espresso extraction: the machine’s calculations don’t always match the coffee’s behavior. The Bambino Plus isn’t malfunctioning—it’s highlighting a disconnect between grind settings and the espresso’s natural extraction dynamics. The Bambino Plus…
