Example Calculations

1Green Tea (Sencha)

Inputs

Tea TypeGreen (Japanese Sencha)
Amount1 tsp (2.5 g)
Water Volume8 oz
Brew StyleWestern

Result

Water Temperature170°F (77°C)
Steep Time1.5 minutes
Re-SteepsUp to 3
Caffeine (est.)25–35 mg

Japanese green teas like Sencha need lower temperatures (170°F) and shorter steeps (1.5 min) to avoid bitterness. The leaves can be re-steeped 2–3 times with excellent flavor.

2English Breakfast Black Tea

Inputs

Tea TypeBlack (English Breakfast)
Amount1 tsp (3 g)
Water Volume8 oz
Brew StyleWestern

Result

Water Temperature212°F (100°C)
Steep Time4 minutes
Re-Steeps1
Caffeine (est.)40–70 mg

Black tea requires a full rolling boil and 3–5 minutes of steeping. English Breakfast is a blend that holds up to milk, so a full 4-minute steep is ideal.

3Oolong Tea (Gongfu Style)

Inputs

Tea TypeOolong (Tie Guan Yin)
Amount5 g
Water Volume4 oz (gaiwan)
Brew StyleGongfu

Result

Water Temperature195°F (90°C)
First Steep15–20 seconds
Re-SteepsUp to 7
Add Per Steep+5–10 seconds

Gongfu brewing uses more leaf (5 g) in less water (4 oz) with very short steeps. This method reveals different flavor layers across 5–7 successive infusions.

Frequently Asked Questions

Q

What is the correct water temperature for different teas?

Water temperature varies dramatically by tea type. Green tea needs 160–180°F (too hot makes it bitter), while black tea needs a full boil at 200–212°F. White tea brews at 160–185°F, oolong at 185–205°F, and herbal teas at a full 212°F boil.

  • Green tea: 160–180°F (71–82°C) – too hot releases excess tannins
  • White tea: 160–185°F (71–85°C) – delicate leaves need gentle heat
  • Oolong tea: 185–205°F (85–96°C) – varies by oxidation level
  • Black tea: 200–212°F (93–100°C) – needs hot water for full extraction
  • Herbal/tisane: 212°F (100°C) – full boil, as these are not true tea leaves

Q

How long should I steep tea?

Steep times range from 1–3 minutes for green tea to 5–7 minutes for herbal tisanes. Over-steeping extracts excess tannins, making tea bitter. Under-steeping produces weak, flavorless tea. The sweet spot depends on tea type, leaf size, and personal preference.

  • Green tea: 1–3 minutes (Japanese greens closer to 1 min, Chinese greens 2–3)
  • White tea: 2–5 minutes (longer steep OK due to delicate flavor)
  • Oolong tea: 2–4 minutes (re-steepable 3–5 times)
  • Black tea: 3–5 minutes (Darjeeling 3 min, Assam 4–5 min)
  • Herbal/tisane: 5–7 minutes (chamomile, mint, rooibos need longer)

Green1–3 min2–3 steeps
White2–5 min2–3 steeps
Oolong2–4 min3–5 steeps
Black3–5 min1–2 steeps
Herbal5–7 min1 steep
Q

How much loose leaf tea should I use per cup?

The standard ratio is 1 teaspoon (2–3 grams) of loose leaf tea per 8 oz of water. Fluffy teas like white or some greens may need 1.5–2 teaspoons by volume. Dense rolled oolongs need only 1 teaspoon. For stronger tea, add more leaves rather than steeping longer.

  • Standard ratio: 1 tsp (2–3 g) per 8 oz water
  • Fluffy white/green: 1.5–2 tsp per 8 oz (light by volume)
  • Dense rolled oolong: 1 tsp per 8 oz (heavy by volume)
  • CTC black tea: 1 tsp per 8 oz (compact granules)
  • For stronger tea: increase leaves, not steep time (prevents bitterness)
Tea TypeTsp/8 ozGrams/8 oz
Green (flat leaves)1 tsp2–3 g
White (fluffy buds)1.5–2 tsp2–3 g
Oolong (rolled)1 tsp3–4 g
Black (orthodox)1 tsp2–3 g
Herbal (dried flowers)1.5–2 tsp2–4 g
Q

Can I re-steep loose leaf tea?

Yes, most quality loose leaf teas can be re-steeped 2–5 times. Oolong is the champion with 3–5 steeps, followed by green and white at 2–3 steeps. Increase steep time by 30–60 seconds per re-steep. Black tea generally only tolerates 1–2 re-steeps before flavor fades.

  • Oolong: 3–5 re-steeps (Gongfu method: up to 8–10 short steeps)
  • Green: 2–3 re-steeps (add 30 sec per re-steep)
  • White: 2–3 re-steeps (delicate flavor diminishes slowly)
  • Black: 1–2 re-steeps (flavor drops significantly after first)
  • Herbal: generally 1 steep only (dried herbs release flavor quickly)
