Start the morning with tea that is still hot at your desk. The bottle holds loose leaves while they steep, then lifts out so every sip is clean. Built from SUS304 stainless steel, it is a daily carry that handles the commute.
Keeps drinks hot or cold longer, and brews loose tea in one bottle
- drinks cooling too fast
- loose tea leaves in drink
- bacteria or odour in bottle interior
- leaking during commute
Brew loose tea in your bottle, and keep it hot longer
Stop reheating a cold, leafy cup at your desk. Brew straight in a vacuum-insulated steel bottle and drink it while it is still warm.
Brew, strain and keep warm in one bottle

Loose leaves stay out of your cup
Add loose tea to the steel strainer, pour in hot water and let it steep right inside the bottle. When the tea is strong enough, lift the strainer out and you drink with no leaves floating on top. The strainer comes out for cleaning, so the next brew starts fresh. Browse the stainless steel tea strainer range if you want a spare.

Vacuum walls that hold the warmth
The body is vacuum insulated with a double wall, and the 3D vacuum steel cover seals the top. Heat moves slowly across the gap, so a morning brew stays hot through the commute and a cold drink stays cold through the afternoon. Keep the lid on between sips and the warmth stays where it belongs.

Made for the daily carry
The cup mouth is smooth and round, so the lip feels comfortable on every sip. The base is non-slip, which keeps the bottle steady on a desk or in a car cupholder. The body is matte and soft-touch, and the SUS304 stainless liner sits inside as authentic food grade steel.
Brew your first cup in the bottle
- 1Rinse the bottle and strainer
Wash both parts with warm water before the first brew so the steel starts clean.
- 2Add loose tea to the strainer
Fill the strainer with loose leaves and seat it inside the bottle.
- 3Pour hot water and close
Pour hot water over the leaves and fit the lid straight away to hold the heat.
- 4Let it steep, then lift the strainer
Give the leaves time to open, then lift the strainer out before you drink.
- 5Rinse the strainer after each brew
Rinse it straight after brewing so wet leaves do not sit in the steel.

Lukewarm tea and leaves in every sip

The cup that goes cold by 9:15
By the time you reach the office, the tea you poured at home has gone lukewarm. Loose leaves float in every sip and the bitter edge builds with each mouthful. Most people accept this as the cost of drinking tea on the move.

One bottle that brews and keeps warm
The detachable strainer holds the leaves while the tea steeps, then lifts out so you drink from the bottle without a second cup. The vacuum double wall slows heat loss, so the tea you brewed at seven is still warm when you open it on the train.

Clean, quiet and ready for the day
The inside is SUS304 stainless steel with an electrolytic inner treatment, so the interior is steel from top to bottom with no plastic lining to hold a smell. The matte body sits well in a bag, the non-slip base keeps it still on the desk, and the lid goes on without a second thought.
Rinse fast, no leftover tea smell
- Lift the strainer after brewing
Rinse it straight away so wet leaves do not sit in the steel.
- Hand wash with warm water
Use mild soap and a soft brush on the interior and lid parts.
- Keep high heat off the finish
Hot dishwasher cycles can wear the matte body and the lid seal over time.
- Air dry with the lid off
Leave the lid off so the inside dries fully and stays fresh.

Questions and answers
Yes. The strainer sits inside the bottle to hold loose leaves while the tea steeps, then lifts out so you drink without leaves. It is detachable, so you can rinse it under the tap after each brew.
The mesh holds whole leaves and most loose blends without trouble. Very fine tea dust can still slip through any strainer, so a dusty tea will leave a little sediment at the bottom.
A single-wall tumbler lets heat leave through the steel quickly. This bottle has a vacuum double wall and a 3D vacuum steel cover, which slows heat loss from both the body and the lid. Tea brewed at home arrives at your desk noticeably warmer.
The liner is SUS304 stainless steel, and the packaging lists it as food grade. The inner wall also gets an electrolytic treatment, which the maker says keeps the surface free of bacteria.
The lid seals against a smooth cup mouth, and the bottle is built to be carried upright. Keep the lid pressed down and stand the bottle upright in your bag, and spills stay unlikely. Pair it with a few other bottles from our insulated bottles vacuum range if you carry more than one.
Think of it as one purchase instead of two. A plain thermos plus a separate infuser costs you a bottle and extra parts to wash, lose and replace. The 304 steel body and liner are sturdy enough for a daily commute, so the cost spreads across months of tea rather than a few weeks of cheap bottles that smell.
