One of the most interesting presentations and discussions
that took place at the
European Beer Bloggers Conference in Dublin
last month concerned the humble beer can. The discussion was led by James
Winans of the
Vanguard Beer Collective; a “one stop shop” organisation for
the promotion, and supply of Irish Craft Beers. The presentation kicked off
with a bit of history to set the scene, then examined the relative advantages
of cans over glass. I have added some of my own thoughts and views on the
matter, and have also researched the rise of the beer can in slightly more
depth.
Persuading consumers to accept beer in cans proved a long
and painful process; a process which only really started to take off during the
late 1930’s, in America.
Although cans were in every day use for the mass distribution of foodstuffs
during the late 19th century, it wasn't until 1909 that the American Can
Company made its first attempt to can beer. This was unsuccessful, and the
company would have to wait for the end of Prohibition in the United States before it tried
again. Finally in 1933, after two years of research, the American Can Company
developed a can that was capable of withstanding pressurisation and which had a
special coating to prevent the beer reacting chemically with the tinplate which
the can was made from.

Some rather non-PC 1930's cans from Krueger |
Canned beer finally made its debut in 1935, when in
partnership with the American Can Company, the Gottfried Krueger Brewing
Company delivered 2,000 cans of Krueger's Finest Beer and Krueger's Cream Ale
to faithful Krueger drinkers in Richmond, Virginia. It is
claimed that over ninety percent of drinkers approved of the canned beer, giving
Krueger the green light to continue production.
The concept of canned beer proved to be a hard sell, but Krueger's overcame
its initial reservations and became the first brewer to sell canned beer in the
United States.
The response was overwhelming. Within three months, over 80 percent of
distributors were handling Krueger's canned beer, and Krueger's was eating into
the market share of the
"Big Three" national brewers--
Anheuser-Busch,
Pabst and
Schlitz. Competitors soon followed suit, and by the end of 1935, over
200 million cans had been produced and sold.
The purchase of cans, unlike bottles, did not require the consumer to pay a
deposit. Cans were also easier to stack, more durable and took less time to
chill. As a result, their popularity continued to grow throughout the 1930s, and then exploded during World War II, when U.S.
brewers shipped millions of cans of beer to its armed forces,
overseas.
After the war,
national brewing companies began to take advantage of the mass distribution
that cans made possible, and were able to consolidate their power over the
once-dominant local breweries, which could not control costs and operations as
efficiently as their national counterparts.
Today, canned beer accounts for approximately half of the $20 billion U.S.
beer industry. Not all of this comes from the big national brewers: Recently,
there has been renewed interest in canning from micro brewers and high-end
beer-sellers, who are realising that cans guarantee purity and taste by
preventing light damage and oxidation.

Cone-top cans from Felinfoel Brewery |
The first British brewery to try tinned beer was
Felinfoel of
Llanelli.
Canned beer was introduced as a means of boosting the local tin-plate
industry, which was struggling at the time. I have seen photos of some of these
early cans. They had a conical top, and were sealed with a traditional
crown-cork. Whilst growing up I can remember certain items being packaged in
these sorts of tins, although as neither of my parents were drinkers, I don’t
ever recall seeing beer cans of this sort. From memory it was substances like
furniture, or metal polish
(Brasso), that were filled into these cone-shaped
containers; perhaps this is why I have always associated tinned, or canned beer
with having a metallic taste.
I do remember having to pierce cans with a pointed
instrument, specially designed for the purpose, and it was necessary to make
two holes; one to let the contents out and the other to let air in. I am
talking about soft-rinks here, but beer was also marketed in these sorts of
cans, which by now had lost their conical top, and looked just like any other
ordinary can.
Aluminium cans first became available in the United
States, during the late 1950’s. Their
lighter weight, and greater durability meant they rapidly replaced the older,
heavier, tin-plate cans. Then in 1959, Ermal Fraze devised a can-opening method
that would come to dominate the canned beverage market. His invention was the
"ring-pull-tab". This eliminated the need for a separate opener tool
by attaching an aluminium pull-ring lever, with a rivet to a pre-scored
wedge-shaped tab section of the can top. The ring was riveted to the centre of
the top, which created an elongated opening large enough that one hole
simultaneously served to let the beverage flow out while air flowed in.
The first “ring-pull” cans I was aware of, featured in an
advertisement of Long Life beer; Ind Coope’s premium pale ale brand. The ad
made great play of the ring-pull, and of the fact the beer was designed and
packaged for home-drinking, and the voice-over said, “Home is where you drink
your Long Life; the beer brewed specially for the home, in ring-pull cans.” Unfortunately,
the only clip I could find of this advert on You Tube was of such poor quality,
that it wasn’t worth including a link to it.
By the 1970s, ring-pull cans were widely available, but they
came with a significant problem, as people would frequently discard the
ring-pulls on the ground as litter, or drop them into the can and risk choking on them.
Towards the end of the decade, Daniel Cudzik's invention of the non-removing
"Sta-Tab" solved the problem. The ring-pull was replaced with a stiff
aluminium lever, and the removable pull-tab was replaced with a pre-scored
round tab with a riveted lever which pushed the tab open and into the interior
of the can.
Today, most people, particularly in the UK,
associate canned beer with cheap, tasteless lager, or equally cheap and
tasteless bitter. However, in other countries cans have a much better image,
and have become very popular in the United States I have
written before on this subject; something which was prompted by
my visit to Japan last year. There
cans are extremely popular, especially on environmental grounds. But cans score
highly in other ways too, being light and therefore easier to transport. They
chill down quicker than glass well, and are ideal for taking on picnics, due to
less weight. Finally, cans are often permitted at events where glass bottles
are not.
Cans therefore win on cost, convenience, ecology and
taste. Although canning costs a lot to
set up initially, once the plant is up and running the ecological advantages of
the can really start to creep in. Advocates of the can, and brewers who are
choosing cans, say there are clear advantages over bottles: The beer in a can
cools quicker. The can protects from beer-degrading light. Beer cans are
portable and take up less space, advantages both for retailers and for
consumers who want to take them camping, hiking or fishing, or to sports or
other outdoor events.. There is also more space on a can for wraparound design
and decoration.

Retro-style Pilsner Urquell cans |
Some quite large brewers are pushing ahead with promoting
cans as the ideal way to store and transport beer, and this was brought home to
us in Dublin at the
Summer Barbecue on the Saturday lunchtime, hosted by
Pilsner Urquell.
There, in the courtyard, was a huge stack of cans, on display, ready for us
to take away and try. What’s more the cans were decorated with some old designs
taken from the brewery’s archives, giving them a real retro look. I brought my cans home with me, but then, rather foolishly,
drank them all without carrying out a taste comparison with the bottled version
of Pilsner Urquell.

A choice of container from Crafty Dan |
However, all is not lost as those good folk at
Beer52 have
come up trumps by including both a bottle plus a canned version of
Crafty Dan
13 Guns;
Daniel Thwaites’ recently launched
American IPA in the case
of beer they sent me recently. I tried both versions
side by side, and have to admit I found it difficult, to tell the difference;
certainly so far as taste is concerned, although I did prefer the mouth-feel of
the bottled beer, which was tighter, if that makes sense. The canned version
seemed looser, and what I think this conveys is that the dissolved gas within
the beer was present as much finer bubbles in the bottles than in the cans.
So much for my rather inconclusive verdict, but from what I
read and hear I would say that the jury’s definitely still out on this one.
What do other people think?
