Re: never seems to taste the same?
Anyway the reason you can't get a decent cup of tea in Spain is they haven't invented the kettle yet.
The Americans have also yet to invent it. Every time I go to Florida on holiday I rent a place, and it always has a filter coffee machine. But no kettle. On the one or two occasions that there has been one, it has been the "put it on the hob for 4 hours until it boils" variety.
