A very beautiful jug. Lovely for pouring water

What makes this special
1.4 litres with a matching lid
The domed lid fits exactly into the rim, with a spout and a sturdy D-shaped handle.
The largest copper surface in the collection
That's why a colour change shows up on the jug first. It's not a difference in quality, just a bigger visible surface.
Independently tested for food safety
Tested to European food safety standards; both the migration and odour/taste tests passed, none of the 19 heavy metals tested for were found. Read the full study under What does research say about copper?
Smooth or hammered
Only the surface differs. Smooth looks understated and calm, hammered gives the large surface extra texture and shine.
A colour change that comes with pure copper
Solid copper changes colour a little on its own as you use the jug. That's completely normal, and even a sign of pure, uncoated copper. If you prefer the shine, simply polish the jug with lemon and salt (not too hard: salt is mildly abrasive and dissolves well in the lemon juice). Exactly how is in the care guide.
Composition
99.21%
copper
99.21% copper, measured independently
The material is analysed by RTC Laboratory in Moradabad, a NABL-accredited lab, tested to ASTM-1621 and IS-228. In the sample that was analysed the measurement came out at 99.21% copper and 0.75% zinc; the remaining 0.04% falls within the measuring range of the analysis. Food safety is covered by a second report, from URS Products and Testing: tested against EC 1935/2004 and REACH, using the heavy metal limits from EU 10/2011 as the benchmark.

What you actually get
In the box
- Copper jug, 1.4 litres, with lid
- Luxury black branded box
- Card with a QR code to the digital guide
The jug is the household size: 1.4 litres, enough to pour four to five glasses. You fill it in the evening, let it stand, and pour for everyone at once the next morning. Where that practice comes from is set out in the article on tamra jal.
It has a matching copper lid, and that is not decoration: water left on the counter overnight is water left open overnight. The lid keeps dust and insects out. The spout is narrow enough to pour without spilling, and the handle stays cool enough to hold.
The jug comes smooth and hammered. At this size the difference is easy to see: the smooth surface gives one continuous reflection, while the hammered piece spreads the light across dozens of small facets. The jug, spout included, is formed from a single piece of copper, with no seam. The handle is brazed on separately, on the outside. Nothing of that joint reaches the inside, so your water only touches the copper jug itself.
There is another reason copper became the tradition. In EPA tests, cleaned copper killed more than 99.9% of bacteria such as MRSA and E. coli within two hours, and since 2008 it has been registered in the United States as an antimicrobial material. It is also a trace element your own body uses, from energy metabolism to the transport of iron in your blood. Stainless steel and plastic are inert and do neither. The evidence is in can copper really kill bacteria.
How to get the most out of your copper
Still drinking water goes in the jug. Fruit juice, squash and carbonated water are too acidic for copper. Refresh the water daily rather than leaving it standing for days.
Wash jug and lid by hand and dry them straight away; standing moisture is where the first marks start. Because a jug has far more surface than a cup, you also see copper's natural darkening sooner here. That is not a fault: why is my copper turning green or black explains how it works, and the care article explains how to polish it back.
Settled in, in six steps
From the first clean to setting out water for the whole family.
-
Clean the jug first
Rub jug and lid with lemon and salt (not too hard: salt is mildly abrasive and dissolves well in the lemon juice). Rinse well and dry both parts right away.
-
Fill it with still drinking water
Just water. No juice, fizzy or acidic drinks.
-
Set the lid on
The lid keeps dust out and sits loose. Lift the jug by the handle, not by the lid.
-
Let the water rest overnight
Set the jug out in the evening and pour in the morning. Drink the water within 24 hours.
-
Wash it by hand
Warm water and a soft cloth, lid separately. Dry right away and store the jug open.
-
Polish it when the shine fades
Every one to two weeks with lemon and salt (not too hard: salt is mildly abrasive and dissolves well in the lemon juice). Polish in sections: on a large surface patina shows sooner.

Made for filling, resting and pouring
From the matching lid to the sturdy handle: discover the details of the Kopero jug.
RTC Laboratory measured 99.21% copper and 0.75% zinc, the same ratio as the rest of the Kopero drinkware. This zinc comes from the production process and isn't an added extra.
The domed lid fits exactly into the rim of the jug, with a wide knob that continues the shape and lifts off easily.
The handle is firmly anchored at top and bottom, clearly visible at the two rivets.
The same shape gets a calm or a distinctly lively character, depending on the finish you choose.
URS Products and Testing tested the jug to European food safety standards; both the migration and odour/taste tests passed, none of the 19 heavy metals tested for were detected.
You unpack a luxury black branded box. So you can give it away straight from the box, without wrapping anything around it.
A Kopero card is inside the box. The QR code on it takes you to the digital manual.

- Fill the product with still drinking water only. Acidic drinks such as fruit juice, soft drinks and lemon water dissolve copper faster and belong in glass. Do not leave water standing in it for more than a day. Wash by hand, not in the dishwasher. If you have Wilson’s disease or another condition in which copper accumulates, talk to your doctor first.

Frequently asked questions about this product
How many people does 1.4 litres serve?
The jug is meant to provide water for the whole family at once: 1.4 litres is enough for several glasses or cups. Set the jug out in the evening and pour everyone a glass the next morning.
Can I put juice, tea or a fizzy drink in the jug?
Still drinking water is what the jug is made for. Juice, carbonation and acidic drinks attack solid copper faster than neutral water and aren't suited to longer storage in copper.
How do I clean the jug and the lid?
Rinse both parts separately by hand with warm water and a soft cloth, never in the dishwasher. Dry the jug and lid thoroughly right away and store the jug open so the inside can dry. Lift the jug by the handle, not by the loose lid.
What's the difference between the smooth and the hammered jug?
Just the finish: the same shape, the same lid, the same spout and the same handle, but in smooth copper the vessel looks calm and understated, while hammered copper gives the large surface extra texture and shine. The jug, spout included, is formed from a single piece of copper, with no seam. The handle is brazed on separately, on the outside. Nothing of that joint reaches the inside, so your water only touches the copper jug itself.
Why do I see the jug change colour faster than smaller products?
Simply because the jug has the largest copper surface in the collection, which makes this change more noticeable. It's completely normal, and not a difference in quality. Take your time polishing it section by section with lemon and salt (not too hard: salt is mildly abrasive and dissolves well in the lemon juice) if you want the shine back evenly all over. Step by step instructions are in the care guide.
For your water ritual
Pour your water into a matching copper cup. A useful addition to your mug or jug.
