Ah, the BIB. I felt like we invented the format over lockdown and then everyone else caught on. It's a bladder inside a box, the same as a wine box. We figured out how to decant cask beer into BIBs so that we could deliver them for people to drink at home. It's a really neat solution because it leaves all the sediment behind in the cask and also extends the shelf life because the beer is in a vacuum and the bladder collapses as it's dispensed so theres no air introduced.
We sourced some fittings as well so could loan people a hand pump for the full pub experience at home, we did really well with those for a while. I do fruit cider in this format now, works well.
