Why "One Cup" tea exists
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.
