in the UK...
Just some more insight from the UK...
The issue of cask shrink has meant that some micros here in the UK are turning to plastic casks. I believe they cost about 1/3 (20 gbp versus 60 gbp) of stainless.
Personally, I cringe a bit when I think plastic, but I know a couple micros giving them a go. This is something that is quite feasible with the bung style cask, probably not so feasible with a Sankey keg...
Anyone in the UK with hands on plastic cask experience? Probably an entirely different thread...
