Strike Water & Step Infusion

How hot to mash in, and how much boiling water to add for each temperature step — straight from a heat balance. It defaults to the grain specific heat that's actually been measured, not the inflated number every other calculator quietly carries, and tells you exactly why. For thicker, heat-driven steps where infusion runs out of room, hand off to the decoction calculator.

The 90% case: how hot the water must be so that hot water plus cool grain settle at your rest temperature.
