Water Temperature Requirements by Tea Type

Optimal brewing temperatures vary by tea type to preserve flavor and avoid bitterness: green tea (155–185°F or 68–85°C), white tea (160–190°F or 71–88°C), oolong tea (170–195°F or 77–91°C), black tea (195–212°F or 90–100°C), and pu-erh tea (195–212°F or 90–100°C).

Steeping Times

Recommended steeping times for loose-leaf teas are:

  • Green tea: 1–3 minutes (shorter for Japanese varieties like sencha)
  • White tea: 2–5 minutes, allowing multiple infusions
  • Oolong tea: 2.5–5 minutes, adjustable for light or dark styles
  • Black tea: 3–5 minutes
  • Pu-erh tea: 5 minutes or more, often rinsed first

Tea-to-Water Ratios

General guidelines from tea experts recommend 1 teaspoon (2–3g) of loose-leaf tea per 8 oz (240ml) of water, adjustable for strength; scale proportionally for larger volumes. Finer leaves like matcha or gunpowder may use less to avoid over-extraction.

Water Quality Effects

Water quality significantly impacts taste: soft, filtered water (low minerals, pH 6.5–8) extracts flavors cleanly without astringency, while hard water (high calcium/magnesium) can dull delicate notes in green and white teas or cause cloudiness in black teas. Filtered or spring water is preferred over tap; boiling reduces chlorine but may concentrate minerals.

Brewing Vessel Materials

Material affects heat retention and flavor:

  • Clay (e.g., Yixing for pu-erh/oolong): Porous, seasons with tea, enhances depth over multiple brews but absorbs flavors.
  • Glass: Neutral, allows visual observation of leaf unfurling, ideal for green/white teas; poor insulation.
  • Porcelain: Inert, even heating, versatile for all types without imparting taste; good for beginners.
Tea Type Temperature (°F) Steep Time (min) Notes on Ratio/Vessel
Green 155–185 1–3 2g/8oz; glass/porcelain to avoid scorching
White 160–190 2–5 2–3g/8oz; glass for delicacy
Oolong 170–195 2.5–5 3g/8oz; clay for aging effect
Black 195–212 3–5 2–3g/8oz; porcelain
Pu-erh 195–212 5+ 5g/8oz; clay (preferred)
Ranges reflect consensus across sources, with variation due to specific cultivars (e.g., lighter oolongs cooler). Use a thermometer or visual cues like steam wisps for precision without equipment.
