I own a pub and it is tied – so can only get 9g casks of real ale.
We sell through enough to have two fixed and one guest ale on at a time, but I want to increase the offering to 2+2. My bright, excuse the pun, idea is to decant a cask into 2 x 20l bag-in-box, these normally giving a longer shelf life.
If you do a search there is no consistency in advice as to how long it will last. Some say 1day if you decant it bright, yet the same brewery also sell bright bag-in-box with a week shelf life. I could decant it live and then let it settle in the bag.
Essentially I am looking to see if anyone has any experience of this and what sort of shelf life you get before dispense (I would imagine somewhere close to the BBD on the cask) and after you start dispense.
I already do it for some cask ciders and it works fine – sell both bags through in 3 weeks.
Any views appreciated.
