What is better: aluminium or stainless steel bottles?

The world of bottles is wider and more complex than one might at first imagine. There is a huge variety of materials in which bottles are usually made: plastic, glass, Tritan, aluminium, stainless steel, etc. Each material has its own characteristics, pros and cons. But in this post we are going to try to answer one of the most common questions, which refers specifically to two of these materials. And that question is: What is better: aluminium bottle or stainless steel bottles?

The best thing to do is to look at the pros and cons separately. And with this information, let everyone choose their preferences:

Stainless steel bottles

Advantages of stainless steel bottles

• They do not transmit odour and taste to the liquid inside, because they are not coated with any other material. This could happen with aluminium bottles.
• It is perfectly suitable for drinks of any kind, hot and cold: water, tea, coffee, soft drinks, etc. Aluminium bottles, on the other hand, are recommended more for water.
• They are resistant, easy to clean and 100% recyclable.

Disadvantages of stainless steel bottles

• The price is usually more expensive than aluminium bottles.
• They can be heavier than aluminium bottles, which are lighter.

Aluminium bottles

Advantages of aluminium bottles

• They are cheaper and lighter than stainless steel bottles. Therefore, when carrying them on excursions, walks... they will weigh less.
• They are 100% recyclable, which helps to protect the environment.
• They are highly resistant to knocks and falls, without deforming.

Disadvantages of aluminium bottles

• It is not good for the aluminium to be in direct contact with the liquid. However, this can be avoided by coating the aluminium with enamels or resins. Make sure that the aluminium bottles you want to buy are marked as "BPA-free" to avoid this disadvantage.
• They are suitable for water, but not so recommended for other liquids.
• They could get hotter when exposed to direct sunlight than stainless steel bottles.

In summary, we could say that stainless steel bottles have the advantage of being safer as they do not need to be coated with other materials, as is the case with aluminium. In addition to being better for any type of beverage. On the other hand, aluminium bottles have the advantage of being cheaper and lighter in weight.
