Okay, when we ”mash” the grain is getting converted from starch to fermentable sugar. The “strike temp” is hotter than the mash temp because adding room temp grain will cool the hot water. This recipe has a step mash with the steps getting warmer.
@IslandLizard has given a great recommendation for reading. As you increase the temp with each step you’ll need to keep the grain off the bottom of your kettle so it doesn’t burn. For the mash we do not boil. If this sounds daunting, perhaps you can use this grain bill with a familiar process. Many brewers have the opinion that step mashing isn’t needed now that grains have been modified. With that said, I’d keep it around 155-158F for an hour. I hope that helps.
I double checked and it was 156F.
This is the steps that I followed for my first beers: I skipped the campdon tablet
Method: In a large stainless steel pot bring your water to 156ºF.
Dissolve the Campden tablet.
Place the mesh bag into the pot, and slowly stir in the crushed Munich malt.
Cover the pot, and maintain 154ºF for 1 hour - wrap in blankets / towels if needed.
After 1 hour, remove the bag of grain and squeeze out as much liquid as possible. Bring the pot to a boil.
Once boiling, add the hops and boil uncovered for 1 hour.
Remove from the stove, and chill the pot to 60ºF as quickly as possible.
Carefully transfer the wort to a cleaned and sanitised 1 gallon jug, add the yeast, and seal with an airlock.
Leave at room temp for 2 weeks out of direct sunlight.
Clean and sanitise pressure rated beer bottles - swing top is best.
Add desired amount of priming sugar to each bottle, and then carefully fill each bottle with beer.
Leave bottles at room temp for two weeks before transferring to the fridge to chill.
