Yesterday I did my first re-brew in 2 years and it was my Yorkshire Bitter, details of the original brew are
here. There's only 2 bottles of it left making it my fastest drinking brew yet so I scaled up to a 23L batch. My water is in line with what folks are saying and I got the figures from
Graham Wheeler's calculator, albeit tweaked a bit and lacking magnesium as I didn't (and still don't) have epsom salts.
Wyeast 1469 West Yorkshire has done soon good work for me; making a brown porter, milk stout and now 2 bitters. I've not had the issues with krausen but I brew 15L batches in young's barrel style fermenter with the screw on lid, markings go to 22L but there's probably close to 30L of space, now that there's 24L fermenting away it'll decide to go crazy and escape... Tends to escape when I make starters of over 1L in a 2L flask, but it's been worth it thus far.
