Rather than throwing the kettle loss away at the end of a brew day I've been letting it settle out then filtering what amounts to a couple of litres into a 5l water bottle. I've been adding dregs of various bottles of beer into it - it's got various saison, kviek, Trappist, brett strains in there. Currently on 3rd gen (I keep some back on bottling then repitch next brew day). I'm getting some interesting beers, and only get 3 or 4 bottles, but never know quite what I'm going to end up with . I think the brett may have been an error, it tends to dominate. If and when I get something really interesting I may use for a proper brew length. Just a bit of fun....
