Brew Day Updates
« on: January 18, 2015, 06:13:20 PM »
I've decided to press on w my brew day, hopefully the chiller won't poison me!

Quick note, mash temp landed at 153.3, looking for 154. Stirred for a minute or so initially. How often should I be checking temp and stirring during the mash?

that's good hitting 153.3. wont notice any different vs 154F.  i'd just check temp at end of mash just so you know your heat loss over the mash period. if its significant, then you cant take steps to insulate next time. otherwise, you're good to go!

I stir until I hit my steady temp, close the lid and leave it shut until vorlauf.


EDIT -  BTW, looks like you did a nice job hitting mash temp.

What they said. Don't open the lid, all that does is cause heat loss

If you're within a few degrees, it's plenty close enough!  Get your temp, close the cooler, and don't open it til you add sparge water.  Every time you open it to check temp, you lose heat.  Even if it drops a few degrees by the end of the mash, it really doesn't matter.

Vorlauf the mash, let it run empty, then add sparge water, stir thoroughly, vorlauf, and let it run empty.

Vorlauf about 6 quarts. Pretty darn clean. When I drained the MT I do see some very small white specks

1-2 quarts is probably plenty, but 6 won't hurt anything.

grain absorption and any dead space in your mash tun....still ok!

Not weird - did you figure grain absorption and dead space ?  Grain absorbs ~ .12 gallons/lb of grain - so 10 lbs grain absorbs ~ 1.2 gallons of water. Dead space is also water you don't get back.

So at this point I should use all 4 gallons of sparge water?

pretty much everything put in from sparge will come out-less a little in the mash and dead space (if any). collect what you need for target preboil volume.

EDIT: by the way, what is your target preboil volume?
