For the Love of Taste Quality taste has been at the heart of Tetley since 1837 - and it's all those years of expertise that make our Extra Strong tea so full of flavour. It's been specially blended for those who want a little more from their cuppa, and only the best leaves make the grade. In fact, our tea tasters try every blend at least 7 times before it passes the Tetley quality test. Dream job!
