Optimal Coffee Extraction is a free iPhone app developed by Andrew Daniels in the Lifestyle category, specifically under Food & Drink. This app was created by coffee enthusiasts who wanted a better way to calculate the extraction of their coffee. By combining modern tools and basic specifications, they aim to measure extraction scientifically and enhance the taste of each cup.

The app boasts a beautiful design that reflects the dedication put into sourcing and producing fantastic coffees. It aims to help both cafes and roasters in their pursuit of brewing the perfect cup of coffee.

For cafes, Optimal Coffee Extraction guides them in aligning with the Specialty Coffee Association (SCA) guidelines for ideal extraction. It emphasizes the importance of preparation and brewing techniques in delivering an excellent coffee experience.

Roasters can also benefit from this app by finding the optimal specifications for their coffee blends. By determining the proper dose, time, and final output for both espresso and filter coffee, roasters can provide their cafes and wholesale clients with the necessary information to uphold quality standards.

To use this app effectively, a refractometer is required, with options like Atago or VST being compatible.
