I prefer loose tea, made with boiling water in a teapot for black tea. For green tea I use water that has gone off the boil, it helps to prevent over-brewing and bitterness.
Whilst I accept that among some tea drinkers there is an element of elitism involved, I prefer loose tea because I've always got more consistent results with it, I know how to brew it exactly as I like it. I've found with bags there can be marked variation within the same pack?
There is the absurd elitism of milk first or second and I remember seeing some chinless wonder aristocrat, on I think that programme by Di's butler, he was bleating that he couldn't have a cup of tea in the morning because the girl put in the milk first, poor dear.
Like all cooking, it isn't adherence to the 'rules', the important thing is you are able to prepare food and drink how you, and your guests like it. I like milk first.
