Default Missing my Mash temp by 6 degrees

I'm currently brewing a nut brown, and I somehow managed to miss my mash temp. I got y grain temp, MLT temp and hit my water temp, and still my mash is at 148 instead of 154! I assume this is just something I need to take in to account next time. But for right now, is adding 1/2 gallon of hot water going to be ok to raise the temp? Do I simply subtract that amount from my sparge?
Thanks!

Yes, the grain/water ratio is much less critical than temperature.

And yes.

Preheating you MLT really helps with hitting your temps. Don't know if you did it or not, but ever since I started doing it 6 months ago, I haven't missed a temp by more than .5-1 degree.

A+ for the preheating the MLT the only way to go. I go in 15 degrees hotter than my strike and wait for the cooler to come down to dough in temp.

I did preheat the MLT, it was at 100 when I doughed in. I put that in to BS and got what my water temp should be and still missed. When I'm all done today I'm going to check my thermometer, see if it's off at all.

What I do is bring my strike water to about 5-8 degrees more than the recipe calls for, and then add most of it to my MLT, cover it and swirl it around, and let it cool to the correct strike temp. Then I add about 1/3 of the grain, stirring, more strike water, more grain, etc, and I hit my temps every time.

If you doughed in while your mashtun was only 100 degrees, that sucked out the heat from your strike water. (I assume it was a cooler setup).

Did you click the little box that says Adjust temp for equipment? Try doing that and see what happens to your strike temp.

Default Water Temps

How many LBS of Malt is going into your all-grain mash?

Depending on the volume of malt, you may need add more water to the mash to hit your temps

i.e. on a Stout I recently had 9# of Malt and started with 3.5 gallons at 130degF. I then added 1.25 gallon of water at 200 degF. I hit 150 degF.

as always....relax and dont worry and have a home brew


Regards,
JC
PS...how did the brown ale turn out?

+ 4 on the preheating the MLT. It also helps to use this strike water temp calculator.

http://www.rackers.org/calcs.shtml

I use it for every batch.
