Brewing tea involves heat. Please be thoughtful about it.
Hot water causes burns. The Calibrated Steep recommends water temperatures between 140°F and 212°F (60°C to 100°C). Water at any of these temperatures can cause serious scalds and burns on contact with skin. Handle kettles with care, pour slowly, and keep hot water and vessels away from edges, children, and pets. Use a tray or heat-protected surface when setting down hot teaware.
Teaware can crack or shatter. Not all mugs, teapots, and vessels are rated for boiling water. Thermal shock — pouring hot water into a cold vessel, or the reverse — can crack glass, ceramic, and some stoneware. Check the heat rating of your teaware. If in doubt, pre-warm the vessel with warm (not hot) water before brewing.
Tea contains caffeine. Most true teas (green, oolong, black) contain caffeine in varying amounts. The amount depends on the tea, brewing method, and your own sensitivity. Pregnant or breastfeeding people, people with certain medical conditions, and people taking certain medications may need to limit caffeine intake. Consult a healthcare provider if you're unsure.
The recommendations on this site are general guidance, not professional advice. The framework here describes how brewing variables affect flavor. It is not medical, nutritional, dietary, or safety advice. If you have specific health concerns, consult a qualified professional.
