Birmingham grocer, John Sumner, came up with the name. Originally, he called it Typhoo Tipps Tea. Typhoo is the chinese word for doctor. The double p in Tipps was originally a printing error but stayed on the pack for years.
For the perfect cuppa the water should contain oxygen. This helps draw out the flavours. Re-boiling the water reduces the oxygen content so it’s not ideal.
Typhoo uses a technique to wash the tea which is highly selective for caffeine. This is thought to give a better flavour than some other methods.
