Quick Answer
To use a glass teapot with a built-in infuser, start by warming the pot with hot water, add loose leaf tea to the infuser, pour water at the right temperature, steep for the recommended time, then remove the infuser to stop extraction. This method works for both black and herbal teas, and a porcelain tisanière offers a similar experience with a built-in stainless steel filter.
A glass teapot with a built-in infuser is one of the most convenient ways to brew loose leaf tea. The transparent walls let you watch the leaves unfurl, while the infuser keeps them contained for easy cleanup. Whether you're brewing a delicate green tea or a robust black tea, the process is straightforward once you know the key steps.
In this guide, we'll walk you through the entire process, from heating the water to removing the infuser at the right moment. You'll also learn common mistakes to avoid, so your tea never turns bitter or weak. If you're using a similar vessel like the Kusmi Tea Tisanière porcelaine 48Cl, the principles are the same—just adjust for the material and capacity.

Why a Built-In Infuser Simplifies Brewing
A built-in infuser eliminates the need for separate tea balls or disposable bags. The infuser sits inside the pot, allowing water to circulate freely around the leaves. This ensures even extraction and makes it easy to remove the leaves when the tea is ready, preventing over-steeping.
Glass teapots are particularly popular because they let you see the color and strength of your brew. This visual feedback is helpful for adjusting steeping time to your taste. However, glass doesn't retain heat as well as ceramic or cast iron, so you may need to preheat the pot or use a tea cozy to keep your tea hot.
- Preheat the glass pot with hot water to maintain steeping temperature.
- Use a tea cozy or warm the pot again if you're serving multiple cups.
Choosing the Right Tea and Water Temperature
The type of tea you brew determines the ideal water temperature. Black teas like the Kusmi Tea Earl Grey or Ceylan OP thrive at 200–212°F (93–100°C), while green and white teas prefer cooler water around 175–185°F (80–85°C). Herbal infusions, such as the Bouquet de Fleurs N°108, can handle boiling water without becoming bitter.
Always use fresh, cold water and bring it to a boil, then let it cool slightly if needed. Avoid reboiling water, as it depletes oxygen and can make the tea taste flat. If you don't have a thermometer, a simple rule is to let boiling water rest for 1–2 minutes for black tea, and 3–4 minutes for green tea.
- For black teas, use water just off the boil.
- For herbal teas, boiling water is fine.
- Never use distilled or softened water—it produces a dull cup.
Step-by-Step Brewing Process
Start by warming the empty glass teapot with hot water, then discard it. Add your loose leaf tea to the infuser—use about one teaspoon per 8 ounces (240 ml) of water, or adjust to taste. Place the infuser in the pot and pour the hot water over the leaves, filling the pot to just below the rim.
Set a timer according to the tea type: 3–5 minutes for black tea, 2–3 minutes for green, and 5–7 minutes for herbal blends. When the time is up, remove the infuser to stop extraction. If your pot doesn't have a removable infuser, pour the tea through a strainer into a serving pot or directly into cups.
- Use a kitchen timer to avoid over-steeping.
- Taste at the minimum recommended time and add more time if you prefer stronger tea.
The 5-Step Brewing Method for a Glass Teapot with Infuser
- Preheat the pot: Pour hot water into the empty glass teapot, swirl it around, and then discard. This prevents the glass from cracking and keeps the water temperature stable during steeping. Checkpoint: The pot should feel warm to the touch before adding tea.
- Add tea to the infuser: Measure loose leaf tea—about one teaspoon per cup. Place it in the infuser basket. For a stronger brew, add a little more, but avoid overfilling the infuser, as leaves need room to expand. Checkpoint: The infuser should be no more than half full to allow water circulation.
- Pour water at the right temperature: Heat water to the recommended temperature for your tea type. Pour it over the leaves in the infuser, filling the pot to just below the rim. For black teas, use water just off the boil; for green, let it cool for a few minutes. Mistake to avoid: Boiling water for green tea will make it bitter.
- Steep for the recommended time: Set a timer: 3–5 minutes for black, 2–3 minutes for green, 5–7 minutes for herbal. Watch the color through the glass and taste at the minimum time. Adjust to your preference. Checkpoint: If you want a stronger cup, add 30 seconds, but don't exceed the max time to avoid bitterness.
- Remove the infuser and serve: Lift the infuser out of the pot and set it aside on a saucer or lid. This stops the brewing process immediately. Pour the tea into cups, using a strainer if any leaves escaped. Checkpoint: The tea should be at your desired strength—if it's too weak, you can add a little hot water to the pot, but you can't fix over-steeping.
