Why "One Cup" tea exists

Source: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for Why "One Cup" tea exists, Tetley One Cup: Engineered for the Single Mug. Canonical: https://teas.co.uk/wiki/tetley one cup engineered for the single mug/

The classic British tea bag was originally designed for pot brewing, multiple cups from one larger bag. The "One Cup" variant is engineered for single mug brewing where:

You want strong tea from a single bag.
You don't want to over steep (bitter).
You don't want to squeeze the bag (mess).
You're in a hurry.

Standard tea bags can brew thin in single mugs because they're designed for higher water to leaf ratios. One Cup compensates with concentrated tea content.

How to brew

1 One Cup tea bag in a mug.
200-300ml just boiled water.
Steep 2-3 minutes (no longer needed).
Remove bag.
Add splash of milk + 1-2 sugars.

The 2-3 minute steep is the design goal, full strength fast.
