Canned revolution: Why UK breweries are choosing cans

05 June, 2017

“The process of canning beers compared to bottling is fairly similar in concept. Both techniques use blasts of CO2 to extract oxygen from the beer, but bottles have a far smaller openning which puts it at an advantage over cans.

“Oxygen is the worst possible additive for beer, therefore the less exposure the beer has to the open air the better. With the rotary systems the cans are sealed much faster so we can be more confident in the quality and taste of our beer."

Ciaran also says that the US has had access to the specialised machinery needed for canning much longer than in the UK. Meantime doesn’t can its beer onsite, mainly due to a lack of space in its warehouse in east London, but also the same old issue of cost.

THE BROWN BOTTLE

Have you ever noticed that Homer and Peter drink from brown bottles that mimic a bottle of Budweisser? As well as a clever piece of marketing by ‘The King of Beers’, there is some science behind the brown bottle.

Ciaran ads, “UV light effects bottles because it penetrates the glass, so if you taste a bottle of beer that’s been left in the sun for an hour compared to one that hasn’t, they would be completely different. Brown bottles are the best for preventing exposure to UV light, but ultimately aluminium cans don’t have this problem.”

Martin Constable, chairman of UK trade body Can Makers, spoke to Drinks International about why he thinks cans are taking over the craft beer industry in the UK.

“The trend for canning craft beer started in the US and the industry is already well-established thanks to small-scale canning machines being available for over a decade. The UK also came from a more traditional cask approach but is catching up fast with the US now - and well ahead of the rest of Europe. 

“From no low volume lines four years ago there are now over 35 craft beer can filling lines in the UK, and off-trade retail sales of 330ml craft beer cans grew by 468% last year.

“Cans have an unparalleled safety record. Sturdy and unlikely to suffer breakages, their tamper-resistant and tamper-evident packaging provides consumers with peace of mind that their products have been safely prepared and delivered.”

THE ART OF CANNING

Another London-based brewery called Beavertown has pioneered the artistic possibilities of canning beer with intricate graphics that almost hypnotise consumers into purchasing its beers. Beavertown founder Logan Plant, joined Drinks International to share his views on the brand’s marketing.

“The can for us is a completely blank canvas and 360 degrees of awesomeness that we can go mad with. There are lots of microbreweries doing it now and it’s wicked for us because we’re really stimulated by our design and our artwork.

“When we started canning three years ago in London there didn’t seem to be many people doing it.

“The size of the 330ml can is hospitable to bars and shelving and fits in bags to take wherever you want.  Ecologically for the amount of cans we can fit on a pallet it’s the perfect size as well – plus the recycling of aluminium is far more cost effective than glass.

“When we’re talking about a fresh IPA there’s no better vessel than a can. It’s a mini keg.”

If you were to watch season eight, episode 21 of The Simpsons, there’s a scene where Lisa asks Homer to recycle his 330ml sized beer cans by drinking the entire crate. This episode was first broadcast in 1997, highlighting the 20-year gap between the US and UK, but it looks as though that gap has finally started to close.

Bottled cocktails: The dos and don'ts

Pre-made cocktails have always carried a stigma, which I find odd. The romance of watching bartenders make drinks from scratch left pre-batched cocktails feeling cheap to many consumers, but lockdowns have forced this attitude to change.
