I'm not taking this 100% seriously but...

Basically, a polypin is a big plastic bottle, usually 4.5 galls (Imp) or 36 Imp pints.  It has a screw lid, which has a tap built into it.  Ok, so you unscrew the lid, fill it up, screw back together again and you have an airtight container.  But, usually, of course, it has a bit of air left in it.  If you fill it with a real ale, it will start to expand as the secondary fermentation takes place..  Using the tap, carefully, you can expel the excess CO2 (and the bit of air left in) and so maintain a good pressure - it's a bit like managing a cask of real ale in a pub cellar.

So, the big question, how long will the beer stay good?  I can't really answer that from personal experience, as I tended to fill mine at an off-licence that sold handpumped real ale on the day of drinking.  The off-licence had done all the necessary spiling and tapping, so the ale was in 'ready to drink' mode.  However, using my experience with homebrew in PET bottles, if the ale was reasonably fresh and contained a reasonable amount of fermentable material, handled carefully, I don't see why you couldn't make it last quite a few days.  If you filled it with good, fresh beer before you left Broadstairs and kept it reasonably cool, it would certainly be ok to drink after, say, 2 to 3 days travel, providing it didn't get too hot.  Whether it would last more than a week, is a big question.  It might, OTOH, it might not.  It would probably be well drinkable but how good, who knows?!

What do you think Andy?
