Chinese Green Tea Brewing Guide: Glass Cup vs Gaiwan
Choose a glass or mug when you want a larger, slower cup and an easy view of the leaves. Choose a gaiwan when you want short, controlled infusions that can be poured out completely between rounds.
Glass or Mug vs. Gaiwan
| Factor | Glass or mug | Gaiwan |
|---|---|---|
| Typical vessel size | About 200–300 ml | About 90–120 ml |
| Leaf direction | Less leaf for more water | More leaf for less water |
| Infusion style | One longer infusion | Several short infusions |
| Pouring | Strain when the cup is balanced | Pour out each infusion completely |
| Useful when | You want a relaxed cup and visible leaves | You want tighter control and repeated tasting |
The numbers below are adjustable starting points. If the package or product page gives specific guidance, use that first.
Glass or Mug Starting Point
- Warm the vessel, then empty it.
- As a trial starting point, add about 3 g of green tea to 250 ml of water.
- Start near 80°C / 176°F.
- Taste after 60–90 seconds and strain when the cup is balanced.
This method makes it easy to watch the leaves and prepare a larger single cup.
Gaiwan Starting Point
- As a trial starting point, add about 4 g of green tea to a 100 ml gaiwan.
- Start near 80°C / 176°F.
- Pour out the first infusion after roughly 15–25 seconds.
- Taste before deciding whether the next infusion needs more time.
Pour each infusion completely into a cup or fairness pitcher so the leaves do not keep steeping between rounds.
Adjust for Leaf Shape and Vessel
- For very tender or small leaves, begin at the cooler and shorter end of the range.
- If the cup tastes thin, change only one variable—leaf amount, temperature or time—and record the result.
- When switching vessels, keep the same tea and water so you can isolate the effect of vessel size and infusion style.
Avoid Vessel-Related Mistakes
- Do not use a gaiwan like a mug and leave the leaves sitting in the full infusion.
- Do not put gaiwan-level leaf amounts into a large mug without shortening the time.
- Do not change the vessel, leaf amount, temperature and water at the same time.
For general bitterness and strength adjustments, use the core Chinese green tea brewing guide.
Choose a Tea for the Comparison
Use one tea in both vessels and keep notes on leaf amount, water volume, temperature and time. Browse the current green tea collection for available teas and product-specific preparation notes.
