As I remember he preferred the latter and suspected that O2 pickup at caskfilling was to blame. It's well known that beer is adversely affected by O2 over some timescales. I wouldn't be surprised to hear that some beers (pale? delicate? hop-forward?) are more susceptible than others.

But then I thi...Firstly, I agree, KeyCask is silly. But then I think that exposing beer to air deliberately is silly. Cask has the advantage of being simple, I'd never disagree with that, but it's disadvantage is that it causes air to some into contact with the beer. Air in contact with beer is rarely good.<br /><br />For us KeyKeg avoids the need for return of containers. Ideal for export and I'd like to send more out to a wider audience within the UK. Also, KeyKeg will stay fresh for longer. Theoretically longer than regular keg as even bottled CO2 contains contaminants.<br /><br />Why serve through handpull rather than keg font? For me, at the moment, it's to prove it can be done. ±Longer term we have the question about why put cask beer through a handpull at all. Some places use FloJets and put through a tap. Why not?<br /><br />I think it is important not to be constrained.

I am hoping at Leeds International Beer Festival to arrange at least on KeyKeg with a low enough level of condition to demonstrate acceptable handpull dispense. No promise though.<br /><br />The problem with beer is that the warmer it is the less CO2 will stay in solution. That KeyKeg I tried to dispense completely at open atmospheric pressure without cooling. Way too much condition for that.<br /><br />Some form of cooling that is appropriate for the level of carbonation is required. I do have a cooler that can be regulated to a set temperature. In fact, it's really easy to modify nearly any flash cooler with bits that can be bought readily.<br /><br />Biut yes, to finally answer your question, if the KeyKeg condition is low enough, and it's in a seller at cask temperature it should be possible to serve through a handpull.Anonymoushttps://www.blogger.com/profile/11319272987951077205noreply@blogger.comtag:blogger.com,1999:blog-2446074078505386356.post-14163230230802620432012-08-30T09:11:03.192+01:002012-08-30T09:11:03.192+01:00Dave,
