Copper Guide

Copper or steel? An honest comparison

We sell both, so here is the straight answer: what each bottle is good at, what it is not, and which one fits your day.

Three kinds of "copper" bottle

Before comparing, know what you are looking at. There are three common types:

  • Pure copper: copper outside and inside. The water touches copper, the traditional tamra jal way. Plain water only.
  • Steel-lined copper (often called steel-copper): copper outside, food-grade steel inside. Looks like copper, works like steel. Any drink.
  • Steel: steel inside and out, often insulated for hot and cold drinks.

Which one should you buy?

  • Choose pure copper if you want the traditional copper-water habit: fill it at night, drink it in the morning. It is also the most meaningful gift for elders, weddings and housewarmings.
  • Choose steel-lined copper if you love the copper look but want to carry lemon water, juice or anything else, or you want less upkeep.
  • Choose plain steel if you mainly need hot or ice-cold drinks for hours.

Many families keep both: a pure copper bottle or jug at home for tamra jal, and a steel-lined bottle for the office or travel.

How to tell them apart in a shop

Look inside the bottle: copper-coloured inside means pure copper, silver means steel-lined. Hold a magnet to the outside: copper is not magnetic. On rivaaaj.com every product page says exactly what is inside, so you never have to guess. Want to check any bottle you already own? Use our at-home purity test.

FAQs

Copper vs steel, answered

Is a copper bottle better than a steel bottle?
They do different jobs. A pure copper bottle is for the traditional habit of storing plain water in copper (tamra jal) and is a classic gift. A steel bottle is easier to care for, can hold any drink and, if insulated, keeps drinks hot or cold. Many families use both.
What is a steel-copper bottle?
A steel-copper or steel-lined copper bottle is copper on the outside and food-grade steel on the inside. It looks like copper but the water only touches steel, so you can use it for any drink. It does not give the tamra jal effect of pure copper.
Can I keep lemon water in a copper bottle?
Not in a pure copper bottle: lemon and other acidic drinks react with copper. Use a steel-lined copper bottle or a steel bottle for lemon water, juice and other drinks.
Does a copper bottle keep water cold?
No. Copper keeps water at a pleasant room temperature but it is not insulated. For drinks that stay ice-cold or hot for hours, use an insulated steel bottle.
Which is easier to clean, copper or steel?
Steel is easier and often dishwasher-safe. A pure copper bottle should be washed by hand and cleaned once a week with lemon and salt to keep it bright.
