Description
A refractometer measures the strength of your brewed coffee, so instead of guessing whether a shot or a filter is under or over-extracted, you get an actual number. It's the tool that takes you from "that tastes a bit weak" to knowing exactly what to change.
Full honesty: this is a nerd tool. You do not need it to make great coffee, and most people never will. But if you're the sort who likes measuring things and chasing repeatability, it's the piece that closes the loop between recipe and result.
- Measures coffee strength (TDS) and extraction
- Works for espresso and filter
- For the data-minded home brewer

What it is, and why it's here
Features that actually matter
Put a number on it
Reads the strength of your coffee so you can tell under from over-extraction instead of guessing.
Closes the loop
Match what you taste to a measurement and know exactly what to change next brew.
Repeatable results
Once you know your target number, you can hit the same strength every time instead of relying on memory and luck.
Dial in faster
Chasing a recipe by taste alone takes ages. A reading tells you which way to move, so you get there in fewer shots.
