S-04 its a hungry beast.......
ferments off very quickly ( can be aggressive I'm told ) easily reaches gravities of 1.010. and settles out solid on the bottom of the fv, so much so the vessel can be tilted 45 degrees and more and it still doesn't move.
I don't know its technical statistics but I've had no problems with it at all.
Last brew I used Nottingham and it was not so good when settled out.
