OK, I've given '05 a shot and it's got it's uses, seems to go really well in the Blande Hallertau Blonde Ale and the pale coloured Cascade flavoured ales.
I'm still not sure it fits in with pale coloured Styrian flavoured ales though. It seems to sharpen up the hop profile too far - to my tastes - or expectations anyway, I'm wanting something mellower.
Now it's a few years since I bought S-04, but I recall it was a full on malt favouring yeast and I didn't get much in the way of hop profile.
I was going to start again with something pretty simple, along the lines of Palmers Crouchback. OG 45 and BU 38 for an 84% ratio - and I'm sure at that ratio S-04 is going to let a little hop flavour through ?
93% ADM 4.0kg
7% Medium crystal 0.30kg
Should get around 1.044 at my standard eff % so say 36 IBU
Of course the FG could screw up the balance completely - what sort of attenuation do you get with '04 for your mash temp on a simple grain bill like this ? How's it compare to 05 ?
