One of my pet peeves is when I go to a pub or restaurant, and I see people sitting near me happily swigging their beer directly from the bottle. I am well aware that bottle-drinking is the norm for the average beer drinker. However, I am also aware that the server brought them a bloody glass and they prefer to ignore it. Now, that is dogmatism.

Leaving aside that it makes you look a bit like a Trailer Park Boy or the guys from Fubar, it destroys the flavour of your beer. It is particuarly irksome when I see some drinking a local craft beer or a quality import directly from the bottle. I remember a couple years ago two college guys sitting at the Sugar Bowl, gleefully glugging from their over-sized bottles of Fischer. Now, I am not including Fischer in any category of quality beer, but the sight of these two guys drinking directly from a 650 ml swing-top bottle was a bit too much for me. Really, guys? Don’t you know what that looks like? It might explain why you are having a hard time finding women to go out with you.

The core of my ire around this issue is that drinking directly from the bottle destroys the flavour of your beer. And I made THAT topic the subject of my latest Beer 101 (read it here). Once again, I know that most readers of this website have moved beyond the introductory class of “use a glass” to the more refined art of deciding which glass is best for which style of beer. But as old hat as not drinking from the bottle is for you, this Beer 101 might have something to teach you – because it did me.

You, I always preached about most of our taste sensation coming from aroma and that the small openings in a bottle or can restricts the aroma, and thus the flavour. (Toss in serving the beer at 2 degrees and you might as well be drinking ice water).

Recently I learned, thanks to Stephen Beaumont, that it has a second effect on your beer. It beats the crap out of it. Stephen was party to an experiment (led by an AB-Inbev rep, no less) where they replicated the effect of drinking straight from the bottle. They poured a beer back and forth between glasses six times. This action was to duplicate the approximate number of sips from a bottle required to drink a 12-ounce beer. By the end, the beer was undrinkable. All the agitation pulled the beer apart.

I did the experiment myself at home and found similar results. Feel free to try it yourself.

So now I have a two-part lecture on why you should always use a glass. And it gave me good fodder to rant in Beer 101 and get a bit of cathartic relief before I next hit a pub and see some guy taking a big gulp from a bottle.
