I saw this in two places in Japan. They poured a can into a little mini 400ml tulip glass, and then sat it on a little metal plate. a head formed. very weird. Tasted as good as your average pint-in-a-pub-where-no-one-drinks-pints. Ultra-sonic you say? I couldn't figure out what was going on at the time and the barman didn't know

I've yet to see the surger in the US, but it certainly is a gimmick. Suppose it helps the beer seem a bit milder by taking a bunch of the carbonation out of it.

[/quote:2pmim5ie] To kenmc's observation, I noted that bottle vs. can difference earlier in my drinking life. When I did a some consulting work at a can manufacturing plant, I noticed that the interior parts of the can that touch the product are coated or passivated so the metal does not react with the product. The exterior is left bare, or at the most the side is primed for painted labels.

So every time I drank beer straight from the can, I was licking the bare metal top, which was something that didn't happen with bottles, due to the entire lack of a metal top once I pried the crown off of the bottle. If I poured the can beer into a glass before drinking it, that odd slight metallic taste vanished.

I've tried the surger and did find the head to be better than a regular can.although i do like the cans and generally drink them straight from the can, i noticed over christmas when a few supermarkets were doing a special on swill that the guinness wasn't great. i do like the bottles too ....its nice to be able to drink 3 different types of a drink and they all taste slightly different. my top tip is out of date guinness cans. ..especially the really old ones with the signature on them in red.they were smaller than the ones we have now. whatever happens with the gas it worked for me.

Hmm...

Sounds like someone needs to do an experiment with one of those ultrasonic jewlery cleaner devices (with no solution in it) and see if we can produce our own "surger"... Maybe one of the ultrasonic toothbrushes could even be rigged up to do the same?
