Field notes
The collection is divided into practical clusters rather than presented as one undifferentiated calculator page. Inputs range from brew dose and beverage yield to refractometer TDS, water hardness, daily shots, boiler volume, and rated burr life. The site also includes unit and language controls, with English, German, Polish, Spanish, and French visible in the navigation.
