I'm Frank, and I built this after pulling one too many sour espresso shots and having no idea what to adjust.
The problem: When I started with espresso, every "dial-in guide" felt like guesswork. Shot tastes sour? Could be grind, could be temp, could be dose, could be your beans, could be the weather apparently. I wanted something systematic.
The solution: The Extraction Compass lets you click where your shot lands (sour + weak? bitter + strong?) and tells you exactly what to change first. The key insight: a washed Ethiopian light roast needs completely different handling than a natural Brazilian medium. So the tool adapts its recommendations based on your specific bean.
The Flavor Wheel: I kept seeing "jasmine, bergamot, stone fruit" on fancy bags and thinking "cool, but how do I find MORE beans like this?" So I made the WCR Sensory Lexicon interactive. Click a flavor β see which origins, processes, and varieties produce it.
What's included: - Extraction Compass for espresso & filter - Ratio calculator with dose/yield lock - Pourover recipes (Hoffmann, Rao, Kasuya 4:6) with timer - Interactive WCR Flavor Wheel - Database: 30+ origins, 60+ varieties, 20+ processing methods
Would love feedback β especially if you spot errors in the coffee data!
Very cool! Could you make a similar project for tea? :) I donβt drink coffee, but I have 6β8 cups of tea a day.
This looks amazing! As a self-proclaimed espresso snob, this is extremely necessary.
Love this. Super practical, zero fluff. The extraction compass plus offline, no-account approach is π₯ for home baristas. Feels like a true use it every morning tool rathar than another coffee blog.
Tastiest launch of the day!
Coffee is a full-on obsession in my house, so this site (especially the troubleshooting section) is an absolute delight.
