How Frederik tests a calendar
- Brews every tea he rates, loose leaf in a pot and bags in a cup, at the maker's recommended temperature.
- Compares a house's loose leaf calendar against its tea bag edition where both exist.
- Looks closely at the craft of the box: materials, how the doors open, and whether it still looks good on day 24.
- Checks current availability at US, UK and EU retailers before each update.
