## Questions & Answers

**Q: What is the maximum coffee temperature for measurement?**
A: The SmartRef can measure liquids between 10°C and 100°C. However we recommend allowing hot liquids to cool to room temperature before measuring.

**Q: How do I calculate the extraction yield with the Coffee Meister mobile app?**
A: Open the ‘Tools’ section, select your brewing method, enter coffee and water weights, import the TDS value, and start the calculation. The app will show the extraction yield and whether your coffee is optimally extracted.

**Q: What is TDS in coffee, and why should I measure it?**
A: Total Dissolved Solids measures the percentage of dissolved solids in coffee, indicating its strength. Espresso has a higher TDS than filter coffee. Measuring TDS helps optimize extraction, ensuring balanced flavor and ideal coffee concentration.

**Q: What are the typical TDS values for different coffee types?**
A: Ristretto: >12% TDS, Espresso: 8–12% TDS, Lungo: 2–8% TDS, French Press: 1.4–1.7% TDS, Filter Coffee: 1.2–1.5% TDS

**Q: What is extraction yield in coffee?**
A: Extraction yield shows how efficiently coffee compounds are extracted from the grounds. It helps assess coffee strength, balance, and taste.
