Gongfu or mug brewing: choosing a method

Both methods steep leaves in water, but use different amounts and timings. Gongfu brewing uses more leaf in a small vessel for repeated short infusions. Mug brewing uses fewer leaves for a larger cup, steeped for a few minutes.

Try the same tea both ways. Use the recipes below to compare the flavour and find a method that fits your day.

Short infusions: small servings, frequent tasting

For an initial oolong trial, use 4–5 g per 100 ml of usable gaiwan capacity, water at 95 °C, and start pouring out 10–15 seconds after you begin adding water. Drain, taste, and adjust the next infusion. These are comparison recipes, not rules for every tea. The advantage is being able to adjust the strength and taste each infusion separately.

A mug or pot: fewer steps

Try the same oolong at 2–3 g per 250 ml, using water at the same temperature and steeping for 2–3 minutes. Remove the infuser or pour all the tea into another vessel. If it is weak, steep longer next time. You can brew the leaves again while they still give a pleasant flavour. A larger cup does not automatically mean a harsh or less aromatic tea.

Why the taste changes

Aromatic, sweet, bitter, and astringent compounds enter the water in both methods. A short steep does not extract aroma alone, nor does a long steep extract only bitterness. With a high leaf ratio, even a few seconds can produce a strong brew. Temperature, leaf size, and broken leaves also matter. A longer steep with fewer leaves can taste gentle.

Choose a method and compare

Short infusions suit tasting small servings and following changes. A mug with a removable infuser suits making one larger drink. To compare, use two fresh portions of the same tea, the same water, and the same temperature. Consider aroma, strength, and aftertaste. You are comparing two complete recipes: because the ratio also differs, you cannot attribute every difference to time alone.

Tips

The number of infusions does not tell you the total yield: serving size and strength also matter.
With either method, separate the leaves from the water when you like the taste.
Grandpa-style brewing with repeated top-ups and cold brewing need their own ratios and timings; do not simply reuse a hot gongfu recipe.
