You pull careful espresso shots. Then you forget everything you learned.
Coffee Rings exists because espresso is a controlled experiment most of us refuse to document.
The uncomfortable truth about dialing in espresso
- You change one variable, maybe two, and trust your memory to connect the dots.
- Advice without your last five shots is noise.
- Progress feels random because yesterday’s data is gone.
Coffee Rings is not about better coffee. It’s about not starting from zero every morning.
"Espresso - Completely Rethought!"
"As a coffee lover, I'm an enthusiastic user of this new app! I've not only learned how good espresso can actually taste at home, but I also understand more and more how small changes in grinding, quantity, or temperature affect the taste."
