Brewing Master Guide
Think of water temperature as the key that unlocks specific flavor compounds inside the leaf. Delicate amino acids (which taste sweet and savory) dissolve at lower temperatures, while heavier tannins and caffeine extract at boiling point.
The Loose Leaf Brewing Master Guide
| Tea Type | Water Temperature | Western Steep Time | Gongfu Steep Time (Asian Method) |
| Green Tea | 160°F – 175°C (71°C – 80°C) | 1 to 2 Minutes | 15 to 30 Seconds |
| Oolong Tea | 185°F – 205°F (85°C – 96°C) | 3 to 5 Minutes | 20 to 40 Seconds |
| Black Tea | 205°F – 212°F (96°C – 100°C) | 3 to 5 Minutes | 10 to 20 Seconds |
| White Tea | 175°F to 185°F (80°C to 85°C) | 3 to 5 Minutes | 15 to 20 Seconds |
Breaking Down Each Tea Type
1. Green Tea: Gentle and Cool
Green tea leaves are unoxidized and highly delicate. If you use roaring, boiling water on green tea, you destroy its fresh, grassy sweetness and end up with a bitter, astringent cup.
- Pro-Tip: If you do not have a temperature-controlled kettle, let your boiling water sit with the lid off for about 5 minutes to cool down to roughly 170°F before pouring it over the leaves.
2. Oolong Tea: The Medium Heat Range
Because oolong teas vary wildly in their processing—ranging from light and floral (like a green Tieguanyin) to dark and roasted (like a Da Hong Pao)—they require a flexible middle-ground temperature.
- Light Oolongs: Stick closer to 185°F to preserve the bright, floral top notes.
- Dark/Roasted Oolongs: Push up closer to 200°F to extract the rich, honeyed, and toasted undertones.
3. Black Tea: Full Rolling Boil
Black tea leaves are completely oxidized and possess a robust cellular structure. They require maximum heat energy to properly break down and release their deeply comforting, malty, and bold characteristics.
- The Exception: High-elevation spring black teas (like a delicate First Flush Darjeeling) prefer a slightly cooler pool of around 190°F so you do not overwhelm their subtle fruit notes.
The Golden Leaf Ratio: For standard Western style brewing (a typical mug), use 1 teaspoon (about 2 grams) of loose leaf tea for every 8 ounces of water.
4. White Tea: Gentle and Hot
Because white tea leaves are light and fluffy rather than tightly rolled, you need a larger physical volume of tea compared to black or green varieties to get the proper flavor profile.
- Standard Western Brewing: Bring your water to a temperature between 175°F and 185°F. If you do not have a temperature-controlled kettle, bring the water to a boil and let it cool with the lid off for about 5 minutes.
- Give them space: Use a wide infuser basket or brew the leaves completely loose in a pot. White tea leaves are large and need maximum room to expand and release their flavor.
- Steep gently: Pour the heated water over the leaves. Steep bud-and-leaf varieties (like White Peony) for 3 to 4 minutes, and delicate bud-only teas (like Silver Needle) for up to 5 minutes
- Separate and enjoy: Remove the infuser or strain the liquid into your mug to stop the brewing process.
Re-steep: Do not throw away the leaves. High-quality white tea can easily be re-steeped 2 to 3 times, adding an extra minute to each subsequent steep.
When brewing white tea using the Gongfu method, you use a high leaf-to-water ratio with short, repeated steeps.
Quick Reference Guide
- Leaf-to-Water Ratio: 5 grams of tea per 100–110ml of water.
- Water Temperature: 185°F to 195°F (85°C to 90°C). Aged white tea can handle hotter water up to 200°F (93°C).
- Vessel: Gaiwan or small clay teapot.
If you are using the traditional Asian Gongfu style, you will drastically pack the vessel with tea (filling it roughly one-third to one-half full), flash-steep for mere seconds, and repeat the process multiple times to watch the flavor evolve!
