What did they do, modify the lid?
Maybe because they have a store bought kegerator with a sanke connector and are afraid to change it out? Or maybe want to swap between sanke and cornie, maybe?
I am sure they do, but it takes all of a few minutes to remove the spear and clean the keg.Since it is welded on, I was going to ask how they clean the keg.
But, since they are pros, I guess they have Sanke washers.
Its easier to use than regular cornies in a bar setting just tap and pour like any other commercial keg.Probrewer seems to have a lot of them for sale. So my guess is that the bigger brewers (bigger than homebrewers) use them. Maybe to sell their Craft Brews to Taverns?
