Learn how to use the Full Leaf Vacuum Flask Tea Infuser for perfect loose leaf tea on the go. Step-by-step guide with tips for a great brew.

Quick answer

Use the Full Leaf Vacuum Flask Tea Infuser to brew loose leaf tea directly in the bottle or steep it separately and pour in for all-day temperature retention.

Why choose the vacuum flask method?

The Full Leaf Vacuum Flask Tea Infuser is designed for both brewing and temperature retention. Its stainless steel construction makes it durable, and the infuser basket secures inside the bottle, so you can steep your tea without any loose leaves floating around.

One trade-off: if you leave the leaves in the flask too long, the tea can become bitter. That's why the step-by-step guide below includes a crucial checkpoint for removing the infuser in time.

How to use the Full Leaf Vacuum Flask Tea Infuser

  1. Prepare your tea leaves: Add your desired amount of loose leaf tea to the infuser basket. A general guideline is 1 teaspoon per 8 ounces of water, but adjust to your taste. Don't overfill the infuser—leaves need room to expand for proper infusion.
  2. Attach the infuser and add hot water: Secure the infuser basket inside the bottle. Pour hot water (around 175-185°F for most green teas, 200-212°F for black or herbal teas) into the flask, covering the leaves completely. Check that the infuser is tightly sealed to avoid leaks when you carry the flask.
  3. Steep and remove the infuser: Let the tea steep for 2-4 minutes (or according to your tea's instructions). Then, open the flask and lift out the infuser basket. You can set it aside or rinse it for reuse. Leaving the leaves in the flask will over-steep and make the tea bitter. Remove the infuser as soon as the steeping time is up.
  4. Seal and enjoy on the go: Replace the lid tightly. Your tea will stay hot for hours thanks to the vacuum insulation. Pour and sip whenever you're ready. If you prefer a milder brew, you can also steep the tea separately and pour the finished tea into the flask for pure temperature retention.
