I have few questions,
If the recipe calls far a dual temp mash, say 30 min @130° then 60min @ 150°, it takes the Grainfather some time to increase 20°. Should it still be 90 min total or 30 minutes at lower temp, then heat to higher temp before starting timer for additional 60 min?
Also I think I am sparging wrong. I have sparged every batch with the sparge water at mash temp. I've since noticed that recipes on the Grainfather app are sparging at 167°. What should I be doing? All my recipes so far have been from the 200 clones book and it does not specify sparging temp.
