We are coffee people that wanted a better way to calculate extraction of our coffee's. Using modern tools & basic specs from our coffee's we are able to now measure the extraction & rely more on science in conjunction with taste in order to produce the best cup of coffee for ourselves and those we serve.

We wanted to produce a beautiful design that helps represent the amount of work we put into our coffee which & our roasters put into sourcing & producing fantastic coffees.

Why would I use this?

Café's: Using quality roasters & quality beans isn't the only thing necessary in serving an awesome cup of coffee. Preparation & Brewing play an important role in a good cup of coffee. Our Optimal Coffee Extraction app will help you find out if you are inline with the SCA guidelines for perfect extraction.

Roasters: Want to find perfect specs for your coffee's that you can give to your café? Finding the proper dose, time, & final output for espresso & filter coffee is a helpful thing to pass onto your café's and other wholesale clients to uphold proper quality standards.

Things needed for this app to work:
A Refractometer, either Atago or VST would work.

What's New

Version Version 2.0

Major UI Overhaul

Improved User Experience

Switched up how you input data, from the pesky sliders to actual inputs you can type on a number pad.

Increased the limits for brew recipes, now it doesn't matter if you make a European Pour-over or an American Sized Batch brew we can measure your extraction properly.

We hope you enjoy and we are always open to feedback on the app. We love hearing from you and have taken a lot of the feedback we have received an implemented it in this latest build.
