One bottle with its cap. With 2 bottles you get a cap on each, and the glasses option adds two plain copper glasses. The canvas sling bag is a separate buy at $30.95.
| Size | 9 × 9 × 29 cm (about 3.5 × 3.5 × 11.4 in) |
|---|---|
| Cap | Copper screw cap with a seal (washer); checked for leaks |
| For | Plain still water at room temperature |
| Care | Hand wash with lemon and salt |
Each bottle is shaped by hand, so small marks and slight differences in tone are normal, even on a smooth body.
The polish fades as bare copper darkens with use, and green spots can form where water stands. Lemon and salt bring the shine back; the care schedule further down says how often.
Free shipping worldwide; delivery times and duty are under Shipping and returns.
We buy this bottle straight from the coppersmiths in India who shape it, with no importer or wholesaler between us. Akshat Goel, our founder, looks over every bottle before it is packed.
Is it safe? Your water sits on bare copper: this bottle is solid copper with no lining, lacquer or coating inside.

Tamra jal is the Indian name for water kept in a copper vessel overnight.
Pour in plain drinking water at room temperature and screw the cap on.
By then the water has stood in the copper all night, as the custom has it. Rinse the bottle before the evening refill.
A fridge magnet and a phone flashlight cover the first two checks, and every row works on any copper bottle, ours or not.
| Check | Solid copper, like this bottle | Copper-plated or lined |
|---|---|---|
| Hold a magnet to it | Does not stick | Sticks if there is steel under the plating (plated aluminium does not stick either) |
| Shine a light inside | The same reddish brown as the outside | Silver, grey, white or glossy |
| Look at worn edges and the rim | Copper all the way through | Silver or grey metal where the plating has worn |
| Feel the weight | About 270 g empty for 1 litre | Plated aluminium feels much lighter for its size |
| Use it for a few weeks | The inside darkens, and lemon with salt brings the colour back | A lined inside stays the same colour |
| Read the listing | “Pure copper”, “unlined”, a named lab and report number | “Copper finish”, “copper-tone” or “copper-coloured”, no lab named |
These checks tell copper from plated metal. Only a lab measures how much copper is in the metal, which is why we name ours.

Two bottles cost $84.95: $42.48 each, and $14.95 less than buying two singles.
| Option | What you get | Price | Per bottle |
|---|---|---|---|
| 1 bottle | One bottle and its cap | $49.95 | $49.95 |
| 2 bottles | Two bottles, each with its own cap | $84.95 | $42.48 |
| 1 bottle + 2 glasses | The bottle, its cap and two plain copper glasses | $79.95 | $49.95, plus $15.00 a glass |
Fingerprints and fine scratches show on a smooth, polished body, so a dry soft cloth after each refill keeps it even. Wash by hand only.
| When | What to do |
|---|---|
| First use | Wash with warm water and a little mild soap, rinse well and dry with a soft cloth. New bottles are mostly smell-free; if yours isn’t, a quick rinse with lemon water clears it. |
| Every day | Pour out what is left from the night, rinse with plain water and refill in the evening. Wipe the outside dry so water does not leave marks on the polish. |
| Every week | Rub inside and out with lemon juice and salt, or diluted vinegar, using long strokes along the smooth body. Rinse well and dry fully. |
| Every month | Look for green spots where water stands and clean them off the same way. On a smooth bottle the outside darkens to one even brown; keep it if you like it. |
| Never | Scouring pads or steel wool, which scratch the polish; also the dishwasher, the fridge, harsh detergent, and hot or acidic drinks. |

Photos: the copper bottle is ours. The steel, plastic and glass bottles are AI images made with ChatGPT, generic examples, not real products.
If you want water kept cold, or lemon in your water, a steel bottle suits that better. This one is for plain water left to stand overnight.


Keep it out of the fridge. Fill it with plain water at room temperature; chilled, hot or lemon drinks go in another bottle.
The name points to Ayurveda: tamra jal, the Indian household custom of keeping drinking water in a copper vessel overnight, is part of Ayurvedic tradition. Nothing lines this bottle, so it suits that custom.
Yes. It is handmade in India and ships from there.
The Ayurvedic copper water bottle is $49.95, $84.95 for two, or $79.95 with two glasses.
Measured on one Ayurvedic Copper Water Bottle (plain). Other products were not part of this report.
Ayurvedic Copper Water Bottle
One that is pure copper, not plated, with bare copper inside and a named lab report. This plain bottle is unlined, holds 1 litre (34 oz), costs $49.95 and is the bottle our lab report covers.
The measured figure and the report number are on the lab card above.
Pick the outside you like. Both hold 1 litre (34 oz), are unlined, have the same screw cap and cost $49.95; this one is smooth and polished, and the hammered bottle has dimples beaten in by hand.
No. There is no lacquer, chemical polish or coating inside, so the water touches bare copper.
Real, solid copper. There is no plating and no steel or aluminium underneath, and it is the model our lab report covers. A magnet will not grip it.
Email us clear photos within 30 days of delivery and keep the bottle until we reply. A damaged or wrong bottle carries no restocking fee. Check the polished surface when you unpack it, since a smooth bottle shows scratches more than a hammered one.

Love it💯💫🔥💖
LOOKS GREAT, WATER TASTES GREAT TOO.
It’s a beautiful bottle! Unfortunately, I accidentally dropped it on the floor and I couldn’t open it anymore.
