Well it’s certainly one view of the country

How many people would drink Guinness if it were not for its association with Ireland?

It might still be a known product, sure. Its following in Africa for example probably has little to do with its Irish origins. But for most people, the images of beverage and country are almost indistinguishable – despite it being owned by British-based Diageo. If you strip away the associations with Irish culture – or what people suppose to be Irish culture – what are you left with? No tradition, no fun-loving attitude, no music and mystery. Just a black drink with a bitter taste and weird texture.

Diageo should ruminate on this. Without the Irish market, there would be little enough market for Guinness.

Ironically these thoughts are prompted by an effort to regain market share in Ireland. I say share; I doubt that Guinness has declined much in total sales, but it remains associated with the more relaxed, conversational drinker. The biggest growth sector – the young, excessive drinker – prefers cider, lagers, alcopops, Buckfast. Any old shit in fact, as long as they can drink a lot of it quickly. It’s hard to drink Guinness quickly. The “Arthur’s Day” programme of concerts by fashionable and/or obscure bands is clearly aimed at attracting the younger crowd. But it threatens instead to kill the goose.

The debate continues elsewhere about what restrictions should be placed on the promotion of alcohol, whether it’s right to aim it at the young through sport or art or even entertainment. That’s not really the problem here though, so much as the sheer scale of Diageo’s vision. The original “Arthur’s Day” was a one-off celebration of the company’s product and history. No one objected to that. Where they overstepped the mark was in turning it into an annual event, virtually a national holiday. That is going a bit far now. Already they push the identification of brand and country to extremes, even to the point of using the national symbol for their company logo. But declaring a new feast day, that’s acting like they own the place.

It’s not a national holiday of course. It’s an enormous alcoholic drink promotion in a country that has an enormous alcoholic drink problem. Such a big event inevitably brings the issue to a head. (I’m sorry, it was unavoidable.) Guinness wants to project an image of Ireland as a land of happy drinkers, where the worst social consequences of alcohol use are perhaps a comical hangover, perhaps a jaw that aches from too much talk and laughter. And not, say, spousal abuse and suicide.

The Sinking Guinness Bubble – Explained!

Guinness drinkers are puzzled about something. OK, after a few they’re puzzled about many things, but the one that gets you even before you start drinking the black stuff is that the bubbles in it appear to rise… downwards. This is not the standard behaviour of bubbles.

You might think that this has something to do with the unusual, possibly supernatural, properties of the famous Irish beer. But no. Scientists have finally torn their attention away from trivialities to explain exactly what is going on here, and it has less to do with the liquid itself than with the glass. Not the special Guinness “tulip” either, but any beer glass just so long as it has the typical tapering shape.

You can read the actual scientific paper here (PDF) if you don’t mind looking at maths, or MIT’s excellent non-technical account. But if you want a loose and more inaccurate explanation which has the merit of being simple enough to tell someone in the pub while they wait for their pint to settle, read on!

Other Irish stouts are also available

Like other beers or fizzy drinks, bubbles form in stout as gas forced in under pressure escapes after the pressure is released. They’re significantly less dense than the liquid of course, and therefore float to the surface – exerting a little drag on the liquid as they do. Now that drag would have no effect in a straight-sided container. All the liquid would feel an equal upward pull, so it would be in balance and none of it could move. But in the slope-sided glass things are different.

This is the crucial bit: There are always fewer bubbles directly above the sloped sides than there are directly above the flat bottom. Therefore there is less upward pull near the sides, more in the centre. This creates an imbalance – the centre goes up, and the liquid at the sides is pulled downwards to take its place at the bottom of the glass. Similar to the convection that occurs when you heat fluids, a “rolling” motion is set up.

Bubbles still want to go up at the sides of course, but the liquid is being pulled down faster than they can rise through it. The net result therefore is that they are visibly dragged downwards. And as we know Guinness is pretty opaque stuff, so though there are actually far more upward-moving bubbles at the centre, we only see the downward-moving ones just inside the wall.

The solution is simple and convincing then: The bubbles at the outside sink because of a circulating motion caused by the bubbles on the inside rising. Next perhaps mathematicians can explain why people drink the stuff when it tastes like wet cardboard.
