Lovely jug, I use it daily for water.

Why copper works
Kills bacteria on contact
Changes the water it touches
A mineral your body needs
Long used for skin and recovery
Lid off, fill, lid on
The lid sits loose and lifts straight off on the hammered version too. Filling and cleaning stay easy, and the water stays covered overnight.
1.4 litres, ready to pour
Four to five glasses from one jug. At this size the difference in finish shows most: the hammering breaks the reflection across dozens of small facets.
What you actually get
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.
What to watch out for
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.
How it arrives
You unpack a sturdy branded box with a Kopero card inside: the QR code on it takes you to the digital manual. So you can give it away straight from the box, without wrapping anything around it.
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. Exactly how is in the care guide.
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. The measurement came out at 99.21% copper and 0.75% zinc. That zinc is not an additive but a residue of the casting process: it makes the copper marginally stronger and changes nothing else. Food safety is covered by a second report, from URS Products and Testing, tested against EC 1935/2004, EU 10/2011 and REACH.

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 casting 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.

Settled in, in six steps
From the first clean to setting out water for the whole family.
-
1
Clean the jug first
Before first use, rub the jug and lid with lemon and salt. Rinse thoroughly and dry both parts right away.
-
2
Fill it with still drinking water
Just water. No juice, no fizzy drinks and no acidic drinks.
-
3
Set the lid on
The lid keeps out dust and rests loosely on the jug. Lift the jug by the handle, not by the lid.
-
4
Let the water rest overnight
Set the jug out in the evening and pour in the morning. Drink the water within 24 hours.
-
5
Wash it by hand
Warm water and a soft cloth, lid separately. Dry both parts right away and store the jug open.
-
6
Polish it when the shine fades
Every one to two weeks with lemon and salt. On such a large surface you'll notice the patina sooner, so take your time polishing it section by section.
The packaging also carries a QR code that takes you straight to this guide.
Reviews of this product
Gorgeous piece, also very decorative.
Our tap water is quite hard. After a night in this jug it tastes much softer and simply goes down more easily.
I fill it after dinner and in the morning we have enough for the whole family straight away. Even the children say the water is fresher.
Wow, that typical swimming-pool smell of our tap water is almost gone. That alone makes the jug worth it for me.
Ayurveda led me to water from copper. A whole jug suits my routine better than separate cups, and I genuinely feel good with it in the morning.
The water gets a softer finish. I still make my coffee with fresh water, but for drinking plain I now want this.
At 1.4 litres there's enough water ready in one go for our whole breakfast.
My partner didn't believe a word of it. Now he pours himself a glass first thing every morning, because he prefers the taste too.
I finally drink enough. Not because the jug forces me to, but because the water tastes less sharp and is already standing ready.
After a few weeks what stands out most is how fresh my mouth feels after the first glass. I now start with two glasses and only then have coffee.
With lukewarm water I taste the difference most strongly. It feels almost silky. Yes, that sounds over the top, but that's how I experience it.
The narrow spout pours steadily and the handle sits firmly in my hand.
I leave the water for about eight hours. The taste turns calm and clean, with no clear metallic note.
A friend who often cooks Ayurvedic food recommended copper water. No miracle cure, but a morning habit my body responds well to. The first few days I drank one glass to try it. These days the two of us empty the jug before breakfast. That never happened with our old carafe.
The smooth shape looks beautiful on our wooden worktop.
The lid completes the jug and keeps the water neatly covered.
After a night the water tastes noticeably mild. My first reaction was genuinely: wow, why can I taste this difference so clearly?
We put the jug on the table without saying anything. Three people asked whether we had different water. I thought that was a fairly strong test.
I use it for my Ayurvedic morning routine. Two glasses of copper water and I feel awake without reaching straight for coffee.
Our limescale-heavy water suddenly feels much softer in the mouth. It's genuinely pleasant to drink.
My stomach responds calmly to water that has stood overnight. That's personal, but for me it's reason enough to fill the jug daily.
The hammered pattern gives the jug plenty of character without looking busy.
I taste no metal. Rather less of that hard tap-water edge. Even at room temperature it tastes good.
Since the jug has been standing there we empty it every morning. That never worked with a glass carafe. Maybe the ritual is half the power.
After two weeks my mornings felt less sluggish. More energy, less need for a second cup of coffee. Really happy with it.
With the lid on, the water seems to stay fresher. I fill it around ten in the evening and pour at six.
The spout pours precisely and the handle feels familiar, even with a full jug.
Ayurveda has long spoken of copper water, so I wanted to experience it myself. For me the difference lies mainly in the taste and a calmer feeling in the stomach.
The children now call it 'the nice water'. I don't need better proof at home. The water tastes surprisingly soft and clean. Even my mother-in-law asked for a second glass unprompted. That was a great compliment as far as I'm concerned.
On the table it draws attention straight away and we often get nice questions about it.
The deeper patina suits the handworked surface beautifully.

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?
No, only use the jug for still drinking water. 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.
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 if you want the shine back evenly all over. Step by step instructions are in the care guide.
Not what you were after? No problem.
You have a 30-day right of return. Copper does take some getting used to: it tarnishes, it feels heavier in the hand than stainless steel, and now and then you will want to polish it. Give it a few weeks. If it is still not what you were after, send it back and get your money back.
