Of course I prefer my beer to be dispensed by handpump (without sparkler) or straight from the barrel with the assistance of good old fashioned gravity. This is natural beer served naturally. Adding gas to a beer is unnatural and unnecessary. It does nothing for the taste and even less for the aroma if that matters to you. Carbon Dioxide is bad enough, nitrogen is much worse.
The biggest bugbear for me though is how long it takes to pour a bloody pint. I haven't done a scientific time trial but I will guarantee it takes less than a quarter of the time to pull my foaming pint of real ale than it does for Mr Old Duffer's pint of Extra Creamy Smooth to arrive. Waiting for my pint is bad enough at the best of times but when the delay is being caused by waiting for some crappy flavourless nonsense to be poured, I'm even more agitated.
Still, I'm off to Coventry Beer Festival tomorrow. No gas there (except plentiful flatulence).
