My system is ready for the switch from 5G extract to 10G AG... I cleaned everything with PBW last night and rinsed... Gonna transfer a beer from my second carboy into a corny and then I should be good to go...

Want to run the mash process by you guys, and I have a couple questions...

I bought a 5G American IPA kit from B3 which was shipped on the third.. It's been in the fridge for a bit more than a week, and I don't want to wait any longer so that it stays reasonably fresh..

I bought a second American IPA 5G kit from them, which was shipped on the 15th..

So I have 2 kits.. each kit has 12lbs 2 row, and 1.5lbs crystal malt 15L

So that's 27 lbs of grain... I want to mash at 154-156 (158 max) degrees, so that I stay on the maltier end of things...

So here's the plan as I understand it...

*) I just removed both kits from the fridge, and set them on the coffee table a bout ten feet in front of the fireplace to warm up to room temp in preparation for the mash a few hours from now... (7-8 hours)

*) I heat up about 10 gallons of water to 180 or better, and dump into the mash tun (48qt coleman cooler) to preheat it while the strike water is heating..

*) I heat seven and a half gallons of water to 170-172 degrees..

*) I dump the preheat water from the tun, and then dump the strike water into the tun from the kettle...

*) I check the temp to make sure it's 170-172 degrees, and then add the 27 lbs of grain and stir

*) I check the temperature, and add hot or cold water if needed to get it to the 156 degree temp I'm targeting.. stir thoroughly

*) Cover and wait 60 mins

??) should I leave alone, or stir during this process

*) while waiting for the mash, during the last 15 mins or so, I heat another 3 gallons for the sparge (I'll be adding ore before I actually sparge)

*) After 60 mins, I collect the first running into a plastic bucket and cover... recirculating the first half gallon into a pitcher until it runs clear..

*) I deduct what I collected from the first running from eleven gallons, and then add enough water to the 3 gallons already heating to equal that amount... I bring the sparge water to about 168-170 degrees, and then dump it into the mash tun and stir...

*) I wait 15 mins and then collect the second runnings into a second bucket (recirculating with the pitcher first)... and cover..

??) should I leave alone during the 15 mins or stir occasionally?

*) I should now have 11 gallons of wort...

*) I add the wort in the two buckets to the BK and check the OG and figure efficiency..

*) I add 2 more gallons of water for boil off, and begin my boil...

If I follow these steps will I be successful?
Is there anything I missed?
Suggestions?

just add hot tap water to the cooler for preheat. it doesn't have to be 180*. close the lid and let the cooler absorb the heat while you are heating your strike water

stir really well at dough in getting all doughballs broken up so all the grain is nice and evenly heated then close the lid. 5 minutes after this point open the lid and take the grainbed temp. if you hit your target, close the lid and leave it at least 60 minutes.

If you are going to add more water to the mash before your first sparge.. add it, stir real good, then settle the bed for a couple minutes, then vorlauf until clear, (slow flow rate at first), then collect the first runnings in your bucket full speed ahead. dump your second batch sparge into the cooler, stir real well, settle the same as the first time, vorlauf, then drain. there is no need to let the sparge sit for 15 minutes in between. just until the bed settles down (couple minutes)
Good Luck.. have fun
 
No need to fill the MT twice to preheat. Simply add the strike water 10-15 above strike temp. Let sit for 15 minutes, then either stir to cool to strike temp, add a couple of ice cubes and stir or just a little cool water to reduce to strike temp.

The sticky up top says to preheat it... You sure this isn't necessary? The tun has been sitting outside overnight in sub freezing temps.... and the ambient temp will likely be in the thirties when I start the process around mid day...
 
Yes you want to preheat it but what I believe he is saying is add your strike water at a higher temp and allow it to come down to your strike temp.

At that point add your grains.

Either way works, do whatever feels good to you.

I just don't want to screw it up.... that would suck! :D
 
I'm not sure what mash ratio your using. 1.25qt/lb gives you 8.5 gallons for mash but 7.5 is fine for a little thicker mash and will let you add hot/cold water if necessary. As for mashing if you have brewing software it should help you with calculating yoru strike temp(temp of the grains vs the temp/volume of the water).

To keep things simple just heat up your strike water to about 180 then add it to the cooler. Throw the lid on and let it heat up and even out. Once it reaches your desired strike temp dump in the grains and stir them up nice and good. Cover and let it sit to stabilize the temp then take a reading and adjust if necessary. You can mash out if you want but it's not necessary and adds another step.

After your hour you can vorlauf as much as you need and then drain it into the kettle when it's running clear. At this point I usually measure what my runnings are and add what's necessary to make up the volume I need with boil off. So lets say you pull out 6.5 or 7 gallons out of the 7.5 you'll probably need >12 gallons total for your boil depending on your boil off rate. So you'll need another 6 gallons for sparging at 170. Let it sit for 10 minutes and repeat the vorlauf/draining. While you're on the sparge you should get the first runnings heated up and ready for the boil.

Considering you're doing your first AG batch and you're doing a 10 gallon one at that, good luck. If it were me I'd do it one kit at a time just incase I mucked up.
 
What exactly does "mash out" mean anyways? I see this term in a lot of recipes, but I'm vague on it's meaning and purpose...
 
Thanks..

So then, if I didn't need to add any water to adjust the temperature of the mash at the beginning, I can add some hot water if I want, to raise the temperature and also dilute the mash a little for improved flow purposes? I might do that...

Or I might just add some water of the desired mash temp in the beginning..

Or should I leave well enough alone, and trust that I won't have any issues with flow from the original 1.1 qts per pound?
 
As long as you open the drain slowly you should be fine. If there is wheat in the kit you have a slightly higher chance of it getting stuck but you should be fine.
 
Another approach to preheating your mash tun:

0. Know your mash tun dead space. Mine is about 2 cups.

1. Boil your mash out water + dead space amount. Toss it in your mash tun.
2. Heat your strike water to a couple degrees above strike temp. (or if you're ballsy, follow your calculator and hit it spot on. I usually don't try it.)
3. Once you're near strike temperature, drain your mash out through your manifold into another pot.
4. Add strike water. Stir or add ice cubes to reach actual strike temperature.
5. Dough in.

This process usually gets me right on in terms of mash temperature.
 
Measured 10 mins after mash was stirred in, is 149 degrees..

That's a little cooler than I wanted, and at the bottom end of the range.. I'd like to heat it up some, so I have a gallon of water heating on the stove... Do I bring it to boil or what temp.. and how much should I add?....

Ideally, I'd like to hit 156 degrees...
 
Can I do it in two pours? I don't want to carry a pot of boiling water that's that full.. (near the brim)
 
At 22 mins, the digital thermometer reads 151-152 degrees.. So I'm not gonna add 'too much' boiling water on the first try.. Maybe 3 qts...

Then stir, wait, and measure again...
 
After pouring 3 qts.. It measured 155 degrees immediately after stirring the mash.. I'll let it sit for about 10 mins and check again.. I bet it goes up a couple more degrees.

Ok so you are doing a AG IPA. I would recomend doing a British style Infusion mash.

Strike- 1.3qt/lb water @ 170 maybe fill your tun with 175f and wait to dough in till around 170, but not below. Stir in well!

Low Mash- Allow to stand for 2hr 35min. Cover and maintain temp. Do not open lid if you do not have too! Wrap with blankets or towels if it is really cold there.

Underlet- Transfer, filter first 1-2qts back through grain bed. allow to stand 30min before sparging.

Sparge- rinse with hot water @ 180f, down to 1.002-3 gravity.
 
Mmmmmm... Smells 'incredible!'

Sorry didn't realize you had already started. I think you will be fine, when I did my first couple AG's I made mistakes... you learn from this. Just take good notes and you will be fine!! Happy Brewing!
 
Man that hour went fast!

Temp stayed at about 150-151 through the mash.. A bit lower than I wanted, but within range... 152 was recommended in kit instructions... I wanted a bit warmer to add maltiness and mouthfeel/body.. But it is what it is...

Extracted 4.5 G wort, heating up 6.5G more for sparge...
 
Don't get too stressed out about your temps not being where you want them. The more times you brew with your setup, the better you'll get to know it. You won't have to ask how many degrees hotter your strike water needs to be to hit your mash temp, you'll just learn what your system requires and do it. Don't forget the most important thing and RDWHAHB! Cheers!

Heat the sparge water during the mash rest next time. Your original post says that you will add water to acccount for boiloff...while this will work...better IMO to sparge an additional amount to account for boiloff...sparge more rather than water down the runnings for better efficiency:mug:

Really? That video I watched from the brew network suggested doing it the way I am, as that will reduce the likelyhood of tannins...

Anyways, I would not have been able to fit the sparge water in my tun... It didn't fit as it was, and I had to get creative..

I just called B3 and they said their kits are based on exactly 5 gallons, so I will only be adding another gallon pre boil, and this of course skewed my OG reading for efficiency..

If someone can help me with the numbers, I read 1.041 with a sample at 122 degrees, with 10% more wort than there's supposed to be... (11G instead of 10)..

I'm hungry and the math is giving me indigestion... target is 60-64.. Mine is pretty low, but temp and volume are skewing it... Trying to figure out if I should add water at all...

On to the boil
