The Helmsley - American IPA

Mash
Heat your strike water to 164°F to achieve a mash temperature of 152°F. The total strike volume for a 7.5-gallon batch will vary based on your kettle size and grain absorption, but approximately 9.5 gallons is a good starting point.
Add your water additions.
Add the grain bag to the hot water and mash in, stirring thoroughly to break up any dough balls.
Mash at 152°F for 60 minutes.
After the mash, remove the grain bag and let it drain completely into the kettle. You can hang it or place it in a colander over the kettle.
