Differences between north and south

I heard today, about north and south pints and how to pull them. Beer, for ths unfamiliar with the word 'pull' in this context.

Apparently a southern pint needs to be drawn slowly, with just a fine skim of bubbles on top of the beer. Southern beers are often heavy, and need to be made peacefully. A northern pint apparently should be jetted into the glass to create a deeper foamy head.

This started as a rant-ette about Australian bar staff and the serving of beer that was too cold by a morris-man, shortly after a question about the etymology of the word 'coaster'.
