Eco Myth Bust of the Month: “Cans leave a metallic taste.” (They don’t.)
If you saw our social post this month, here’s the deeper dive. The short version: modern aluminum cans are designed so the beverage never directly touches the metal. Inside the can is a thin protective liner that acts as a barrier between the drink and the aluminum. That means the flavor inside is the flavor the brand intended, not something added by the can. On top of that, cans help protect beverages from light and excess oxygen exposure, which can affect freshness over time.
WHY PEOPLE THINK THIS
Drinking from the rim
Sometimes what people notice is the feel or temperature of the can itself, not the liquid inside.
Perception vs. product
Packaging can influence how we experience a drink, but that does not mean the can is changing the flavor.
Old assumptions
A lot of people still picture bare metal, when in reality beverage cans are engineered with interior protection built in.
HOW CANS ACTUALLY PROTECT FLAVOR
Protective liner inside
The beverage is separated from the aluminum by an interior coating designed for product safety and performance.
Blocks light
Unlike clear packaging, cans keep light out, which helps protect taste and quality.
Limits oxygen exposure
Less exposure helps beverages stay fresher and more consistent from filling line to first sip.
WHY THIS MATTERS FOR BEVERAGE BRANDS
Flavor consistency matters
Customers expect the same taste every time they open a can.
Packaging does more than look good
A can is not just branding, it is part of how the product stays protected through shipping, storage, and sale.
Freshness supports shelf appeal
When packaging helps preserve what is inside, brands get both performance and presentation.
What about the “metal taste” people swear they notice?
Most of the time, that comes down to perception, not the drink itself. The scent, chill, and feel of the can can shape the overall experience, especially when sipping directly from it. But the liquid inside is not supposed to be picking up a metallic taste from the aluminum.
For breweries & beverage brands
If flavor protection matters, cans are doing more work than people think.
If your product depends on freshness and consistency, packaging choice is part of the equation.
Want a package that helps protect the drink while still showing up strong on shelf? Aluminum cans are built for both.
