Learn how to use your Flat Tummy Tea Infuser to brew refreshing iced tea at home. Step-by-step instructions for hot brew and cold brew methods.

Quick answer

You can make delicious iced tea with a tea infuser using either a hot brew method (steep strong tea, then pour over ice) or a cold brew method (steep in cold water in the fridge for 8-12 hours). Both work great with your Flat Tummy Tea Infuser.

Hot brew vs. cold brew: which one for you?

Hot brewing extracts flavor quickly and gives you a more traditional tea taste. It's perfect when you want iced tea in 15 minutes. Cold brewing takes longer but produces a smoother, less bitter drink with lower acidity. Choose cold brew when you have time to plan ahead and want a gentler flavor profile.

Both methods work with any loose leaf tea. The key is adjusting the tea-to-water ratio since the ice will dilute the hot brew.

Step-by-step: Make iced tea with a tea infuser

Choose your method and measure the tea: For hot brew: use 1.5 times the usual amount of loose leaf tea (e.g., 2 teaspoons instead of 1.5) to account for dilution from ice. For cold brew: use the same amount as you would for hot tea. Hot brew needs extra tea; cold brew does not.
Fill the infuser and steep: Open the Flat Tummy Tea Infuser, add your loose leaf tea to the removable strainer, and close it securely. For hot brew: pour 8 oz of just-boiled water over the infuser and steep for 3-5 minutes. For cold brew: fill the infuser with cold filtered water and place it in the refrigerator for 8-12 hours. Don't over-steep hot tea — it becomes bitter. Cold brew is forgiving, so longer steeping is fine.
Remove the infuser and add ice: Take the infuser out of your cup. For hot brew: fill a separate glass with ice and pour the hot tea over it. For cold brew: your tea is already cold — pour it over fresh ice or drink it straight from the infuser. Pouring hot tea directly over ice shocks the tea and can make it cloudy. Let it cool slightly first.
Customize and serve: Add sweetener, lemon, or fresh herbs like mint to taste. Stir well and enjoy immediately. The stainless steel infuser keeps your drink at the right temperature longer. Add sweetener while the tea is still warm (for hot brew) so it dissolves fully.
