Crystal Tea Infuser Bottles

Brewing loose leaf away from the kitchen

An infuser bottle solves a narrow problem well: you want loose leaf at a desk, on a train or at the gym, and you do not have a pot, a strainer or anywhere to put wet leaves.

How the crystal chamber works

These bottles hold the crystal in a sealed compartment separate from the water — the stone is never in contact with what you drink. That distinction matters. Loose crystals sitting in drinking water are a genuine safety question, because some minerals are not inert and small stones are a choking risk. A sealed chamber sidesteps both.

Getting a decent brew from one

The main difference from a teapot is that the leaves stay in the water. That is fine for the first fifteen minutes and increasingly bitter after that, so:

• Use about half the leaf you would use in a pot.
• Choose forgiving teas. Rooibos, herbal and fruit blends stay drinkable after long steeping; green tea and delicate whites turn astringent quickly.
• Water off the boil, not on it — around 80°C for green, boiling only for black, herbal and rooibos.
• If you want it to last all day, tip the leaves out once it has brewed properly.

Care

Hand wash, and rinse the infuser section as soon as you finish rather than at the end of the day. Tea residue left in a warm sealed bottle is the fastest way to make it smell.

What to put in it

Start with a rooibos or a fruit blend — both are hard to over-brew. Browse the full loose leaf range, or see the infuser teapots if you mostly drink at home.
