Free specialty coffee tools by Álvaro Magri, coffee scientist: water remineralization and blending for coffee, SCA water evaluator, grind recommendation for grinders, recipes and articles on extraction.
This is Álvaro Magris hub of free specialty coffee tools: water calculators (remineralization, blend and evaluation), grind recommendation for grinders, a flavor wheel, a pouring coach and step-by-step recipes.
The idea is to bring the science and practice of coffee together in one place, helping you control the variables that most affect the cup: water, grind, extraction and sensory perception.
Everything runs right in the browser, on your phone or computer, with nothing to install.
It is coffee scored 80 points or higher on the SCA sensory scale, usually traceable to its origin and free of defects, with flavor and aroma attributes that set it apart from commodity coffee.
They are calculators and guides that help you control brewing variables such as water composition, grind, extraction and sensory description, making the result in the cup more consistent.
Yes, the main tools are free and work without sign-up. Some advanced features are premium, but the essentials are open to everyone.
The drink is mostly water, and its hardness and alkalinity directly influence extraction and flavor. That is why there are tools dedicated to evaluating, blending and remineralizing water for coffee.
Not necessarily. With good water, an appropriate grind and attention to the extraction variables you can already improve the cup a lot, and the tools here help precisely with that control.
