I am brewing the pm version of this tomorrow. Two questions, how long should I mash for and how much water should I sparge with?
I've done all of one PM batch (this one, probably the best beer I've ever made) so take this with a grain of salt. But after reading DeathBrewer's indespensible
PM tutorial, I did the following:
- 1.25 quarts water per lb. grain. (I used 1lb Munich, 1lb 2 Row, and 1/2 lb each of Carafoam, Crystal and Melanoiden, so 4.4 quarts water).
- Target mash temp of 152 F. Using the
online calculator Deathbrewer recommended, I heated to 167 F with the goal of dropping to 152 F after my room temp grain was added. My temp went a bit lower after adding the grains so I added a little boiling water to get back to 152 F -- next time I'll probably heat to 170 F before adding the grain. If you're mashing in a pot, cover it with a towel/blanket to minimize heat loss during the mash.
- I intended to mash for 45 mins but got busy and left it for 1.5 hours. Everything I've read suggests 45 mins should be plenty though. After mashing I wrung the grain sack out and set it aside, and then tossed in the first wort hops.
- I "sparged" by bringing the remainder of my boil volume (5.75 gallons) to 160 F, killing the heat and letting the grain sack steep in that for 15 mins. (after which I wrung it out again and then discarded).
- To complete the story, I used 8 lb LME in the boil. With all of the above, my OG and FG were dead on, and as I say this beer is incredible. Will definitely be making this one again.
