How It Works

How to Calculate Tea Steeping Time

Guidelines by Tea Type

| Tea | Temperature | Time | |-----|------------|------| | Green | 165-180°F | 1.5-3 min | | White | 175-185°F | 2-4 min | | Oolong | 185-205°F | 2-4 min | | Black | 200-212°F | 3-5 min | | Herbal | 212°F | 5-7 min |

Key Principles

  • Temperature matters more than time. Green tea becomes bitter in boiling water regardless of steeping time.
  • Loose leaf tea generally needs 1 teaspoon (2-3 g) per cup with room to expand.
  • Tea bags steep slightly faster because the leaf is cut smaller, increasing surface area.
  • Multiple infusions: Oolong and pu-erh can be steeped 3-5 times, adding 30 seconds each round.

    • Worked Example

    2 cups of loose-leaf black tea at 3 g per cup.

    tea_type = 4format = 1cups = 2tea_grams_per_cup = 3
    1. 01Steeping time = 4 x 1 = 4 minutes
    2. 02Total tea = 2 x 3 = 6 g (about 2.4 tsp)
    3. 03Total water = 2 x 237 = 474 mL
    4. 04Use boiling water (212°F) for black tea.
