So which is better? Canned beer or bottled beer?
Does it affect the taste?
A lot of beer lovers aren’t too fond of the idea of drinking beer from a can. That has a lot to do with the past: not too long ago, untreated tin was used as packaging and the metal gave the beer a bad flavour. I for one am old enough to remember the awful metallic taste that tainted the canned food of my youth. It tasted like blood. But those days are over now, as there are various coatings inside the tin to prevent unwanted tastes.
Then heavier alcoholic lagers became available in pint-sized cans at very low prices, and thus became the beer of choice for people who spent their days drinking on park benches, which for many consumers is an undesirable association.
There is no better packaging for beer than cans.
If you’ve not heard about the benefits before, here’s the top line: cans are the best way to protect beer against the inevitable decrease of flavour over time. Beer is a product made from natural ingredients, and therefore, sadly, does not have an eternal life. The taste reduces rapidly when beer is exposed to light, air and high temperature. Light, especially UV-rays, react with hops and cause nasty sulfur compounds - but tin is 100% light-tight, and thus beats every bottle. Oxygen reacts with beer and causes it to oxidize, making the beer smell like a wet newspaper - but tin is also 100% airtight. The colder a beverage is, the slower biochemical processes that cause the taste to slowly deteriorate - cans cool faster than glass.
Reduce, reuse, recycle
Let's not fail to mention the countless environmental benefits of using cans. Aluminum can be recycled indefinitely, in fact 75% of aluminium produced since 1888 is still in circulation today. Recycling a can also uses 95% less energy than it does to produce a new one. Aluminum is actually the most recyclable material on the planet because of its lower density and thus, lower weight. This means it’s cheaper to transport, making for a smaller carbon footprint and therefore reduces emissions.
Point is: cans are, especially for flavoursome beers, the superior beer packaging.
