Advice for the perfect tea round from Tetley tea’s master blender Sebastian Michaelis: 1.Tea should be made with boiling water, and only once-boiled water with a low mineral content.

2.For black tea, pour the water as soon as it’s boiled to deliver the best taste.

3.For green tea, allow the kettle to cool for up to two minutes to avoid a bitter taste.

4.For tea bags, add the milk after the water to avoid hindering the infusion process.

5.Leave the tea bag in for at least two minutes to let the flavour of the tea infuse.

6.After removing the tea bag, leave the brew to cool for two minutes for a better quality taste.
