Interesting Article: 'Does carbonation have a taste?'

[KEG]

Not really beer related, but interesting all the same.

Nice

Would like to know more about the science of how it works though

[Kevnlis]

I do truely believe beer tastes different when forced carbonated rather than naturally in a bottle. The forced carbonation has more of a tangy metallic sort of taste.

[blandy]

Perhaps that is due more to the absence of yeast than the presence of something else.

no idea, just hypothesising is all.

I find it the case with CPA as well, when I lived in SA I drank nothing but CPA all day every day, and it tasted much different from the pub than it did from the bottle.

I have noticed it with home brew as well though, the same batch tastes different from the keg than from a bottle.

Give it a go and see if I am just crazy

[blandy]

The way to test my hypothesis would be to compare a filtered beer from the tap and bottle.

Another thought is that the flavours of the keg metal are coming into the brew .

I agree Blandy

In the keg vs bottle taste debate, there are more variables other than carbonation.

Aside from the metal from the keg, there's also the age of the beer and in the case of a non-filtered beer, the fact that beer ages differently and develops different flavour depending on volume of beer and yeast.

I would agree that kegged beer hasa distincly different taste.

As for differences in carbonation, as far as I'm concerned it's a conclusive fact that carbonation levels change the taste of a drink.
