About This Project

espresso-extraction-troubleshooter.hub2.day is a focused independent web utility built around Espresso Extraction Troubleshooter.

What This Site Does

A diagnostic tool that helps home espresso drinkers figure out why their shot tastes wrong — sour, bitter, weak, or channeling — based on grind size, dose, yield, and time inputs.

Who It Helps

Home espresso enthusiasts, new machine owners, and anyone pulling shots that don't taste right and don't know which variable to adjust
