For hop utilisation you're normally looking at a SG of 1.040. You add your hops to that while it's on the boil and bingo bango you start your timer.
I'm certain all the advice given so far regarding the amount of hops refers to a SG of 1.040. I'd be shocked otherwise.
Hop utilisation is highest in plain water. It is most suitable in 1040 wort (or a gravity reflecting that of your finished (but not fermented) wort).
Just wanted to say thanks to all you guys for the help, and in light of Manticles pearls of wisdom ;-), thought I'd lay something down.
Just put in the fridge:
1.7kg Coopers Traditional Draught
1.5kg Amber Malt Extract
300g dextrose
30g Cascade @ 60 mins
10g Cascade @ 30 mins
10g Cascade @ boiled in the AME with dextrose for 15 mins
US-05 yeast pitched about 22 degrees. Should ferment in the fridge about 16 degrees.
Thinking of dry hopping about 15-20g Amarillo after about 7 days.
Cheers all.
:lol:No wonder they rarely do what I want them to.
It's not too warm here in Adelaides north (28-30 during day down to about 14 at night) so should be able to shut door of fridge at night and leave it slightly ajar during the day.
