I generally read ukfdra via google & don't bother clicking on the small text ads that appear at the side (envilleales.co.uk have been up there recently) but today I noticed an ad from Giles Enterprises (never heard of them before -
I saw their "Filt-A-Cask"(c) mentioned & thought, "oh good, a device that filters out solids from your slops before you return them to your cask" then I started reading & saw CAMRA was mentioned & the word "breather" (as in blanket CO2) well, it's *not* either of those at all, thankfully - it's actually a set of filters & a non-return valve that fit into the spile-hole to stop airborne infection of beer, while still allowing clean air into the cask, as the beer is drawn off.
They say that the non-return valve removes the need for hard/soft pegging (similar action to the "race spile"?)
Interesting stuff, anyone know of a pub which uses them & their opinion of them?
BTW I have no connection to the company, just seemed like a good idea that I'd not seen before. cheers MikeMcG.
