Is beer in cans better?
The craft beer revolution always manages to surprise. Hop-forward, bitter beer has been put back on the map. The beer world has begun experimenting with yeast and malt. And now we’re seeing oats along with other ‘ancient grains’, taking up centre stage beside traditional grains like barley, wheat and rye.
The result of all this experimentation is clear: beer now comes in many different colours, smells and flavours. And it’s not just the beer that's changing. Huge improvements are also being made in packaging, specifically with the reintroduction of cans...or tinnie to some of us. The question is: should we be happy about canned beer making a comeback?
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. It tasted like blood. But those days are over now, as there are various coatings inside the tin to prevent unwanted tastes.
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. Aluminium 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. Aluminium 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.
Canned beer in America
Beer in cans originated as an American invention. Since 1909 businesses have been experimenting with canned beers, but the cans simply weren’t strong enough and they exploded on the assembly line.
On 24th January 1935, Gottfried Krueger Brewery put them into production. Technical innovations led to workable packaging - but these cans did give off a bad taste. It wasn’t until the end of the last century when these barriers were overcome, and in 2002, Oscar Blues from Colorado became the first craft brewery to pack beer in cans.
In the USA alone, 30% of all the beer sold is now in cans.

Canned beer in Europe
Scepticism is now slowly being replaced by admiration in Europe, too. Small, independent breweries in particular are opting for cans instead of bottles. Certainly, when it comes to beer with a strong aroma, such as lager, IPA or Hefeweizen, cans are emerging as a better option.
German brewery And Union as another great example: they make lagers, Hefeweizen and IPA, all in cans.
In the Netherlands, small and independent breweries have not exactly been ahead of the canned beer game either. However, in recent times many Dutch brewers have added cans to their assortment. These include, but are not limited to, Two Chefs Brewing and their Funky Falcon Pale Ale and Walhalla. Walhalla brew a very delicious raspberry Berliner Weisse, also available in a can!
Bevog brewery, originally a Slovenian brewery but now located in Austria, joins the acceptance of beer in cans. Their more aromatic beers are canned, but the beers that can take more a beating are bottled.
Canned beer in the UK
The UK generally has historically had less doubts about cans - perhaps they’re a tad more open-minded as a country that so openly embraced cans of baked beans and tomato soup. Leading breweries such as Magic Rock, FourPure , Wild Beer Co and First Chopoffer a wide range of craft beer in cans.
