Our Verdict
Sage Smart Kettle is for those who know that water temperature is an ingredient. Green tea scalded at 100°C loses its flavour — 80°C preserves it. Pour-over coffee at 93°C extracts differently than boiling. 14,800 reviews at 4.7★ from coffee and tea enthusiasts who measured the difference in their cup.
