Tomorrow if I do it, it'll be my second batch. The first I pitched at 75, although I'll probably aim for 70 on tomorrow's batch. I think partly the reason for it coming down so fast is that the water pressure in my house/hose is incredibly strong. Showers are painful at full blast, and I didn't turn the chiller on full blast for fear of blowing apart the elbows I put in the chiller (it's a home-made jobby, and while I may not qualify as the worst handy-man in the world, my chiller is far from the prettiest ever made).
Hmmm, according to Papazian's instructions it takes at least 30-40 mins to prep the yeast, but I'm not sure if his instructions are out of date? What's the fastest way to effectively hydrate yeast?
