I'm trying something similar this Sunday.
This will be a light amber ale, mostly grain, with a little cornstarch added to the mash.
125* for 15 minutes.
145* for 30 minutes.
155* for 30 minutes.
Mash out at 170*
Two sparges, each at 170*
I'll be using my heatstick to do the temperature increases.
(Oh, and it will be 65* and sunny here)
