These links were posted on the GBF, but I thought some of you might find them interesting.

Interesting info, thanks for posting.

So where do we get the good stuff?  :wink:

Not a problem for naturally carbonated beers.

Except maybe that you’re pushing them out with CO2?

?

He means if kegged. If you keg condition, you still need to use co2 to push the beer out of the keg.

Unless you use a cask…

I just bought one. Won’t be able to cask all my beers, since I can’t finish them that quickly. However, all “special” beers (for thanksgiving, parties, etc.) will likely be cask conditioned and served via gravity tap.

Might even try it with a lager, though I’d obviously have to deviate from traditional methods to try and make it work.

Ah, thanks. I don’t use kegs so didn’t understand the reference to pushing.
