WATER
Always select the purest water available. Filtered water is recommended. When possible, choose soft water, since a high calcium content (found in mineral or tap water) gives rise to deposits on the surface of the cup, affecting the taste of the tea.
TEMPERATURE
To bring out the full complexity and flavour of the tea, the ideal temperature for the perfect infusion varies according to the type of tea. For the highest grade white teas, yellow tea, and green teas, the water should be heated to 70°C (158°F). For other varieties of green teas, blue teas, black teas, matured teas and red teas, the water should be between 90°C (194°F) and 95°C (203°F) – this helps the water to maintain its dissolved oxygen content, which is essential to bringing out the flavour of the tea.
