Insulated Tea Flask with Infuser & Temperature Gauge - 820ml Thermal Thermos

This 820ml stainless steel tea flask has a built-in stainless steel infuser and a mechanical temperature gauge on top, so you can see the water temperature without opening the lid. We use these at our Salamanca Market stall on cold Saturday mornings — they keep ripe puerh and aged white tea hot for a full shift.

What's included

• Capacity: 820ml
• Material: 316 stainless steel body, food-grade stainless steel infuser
• Insulation: Double-wall vacuum — keeps tea hot 6-8 hours, cold 12+ hours
• Temperature gauge: Mechanical (no batteries needed), reads 0-100°C
• Infuser: Removable fine-mesh basket, sits inside the flask

This works well for

• Taking loose-leaf tea to work, hiking, or road trips
• Market days or outdoor events where you want tea on hand
• Ripe puerh and aged white tea — teas that hold up to long steeping
• Anyone who wants to see the temperature before opening the lid

The temperature gauge is a handy feature if you're brewing green or white tea and want to make sure the water has cooled enough before adding leaves. For darker teas like ripe puerh or aged white tea, just fill and go — they're forgiving with temperature.

Joanne's tip

This flask goes with us to every market. If you're brewing ripe puerh in it, use a bit less leaf than you normally would — the long steep time means the flavour builds up. About 4～5g of leaf to a full flask works well. And rinse the leaves once with hot water first before filling up.

How to use — brewing tea

Start by rinsing the flask with hot water to warm it up, then pour that water out. Add your tea leaves directly into the flask — about 4-5g for a full flask is a good starting point. For ripe puerh or aged white tea, pour in a small amount of hot water to rinse the leaves, then pour it out through the filter. After that, fill the flask with fresh hot water and close the lid. The built-in filter sits at the spout, so it catches the leaves when you pour.

Steeping time depends on the tea. Most teas do well with 30 minutes to an hour in the flask. Ripe puerh and aged white tea are forgiving and can sit longer without getting bitter. For lighter teas like green or white, check the temperature gauge first — wait until it reads around 80-85°C before adding the leaves, and keep the steeping shorter.

How to use — as a thermos

You can also use this as a regular thermos — just pour in whatever you like. It keeps hot drinks hot for 6-8 hours and cold drinks cold for 12+.

About the lid

The lid has a twist knob with a small grey line on it. Line up the grey mark with "On/开" to open the pour spout — water flows out when you tilt the flask. Turn it to "Off/关" to seal the spout shut. If you're putting the flask on its side in a bag, make sure the knob is turned to Off/关 and tightened properly. You'll hear a noticeable click when it locks into Off position — it's louder than the On click, so you can tell by sound that it's sealed.

Care and use

Rinse the infuser and flask with hot water after each use. The temperature gauge sits on the outer lid and doesn't come into contact with the tea, so it stays clean. Avoid using abrasive cleaners on the stainless steel interior. If tea stains build up, soak overnight with a teaspoon of baking soda and warm water.
