First partigyle attempt (IIPA + APA)
 
<edit 1/18/2010> I'm mashing right now. I'll add a new post to the end of this to show what's going on</edit>

Ok, Here's what I've come up with. I got the estimated gravity readings from Mosher's Brewing Techniques article

80% eff gives me a 1.063 regular batch with this grain bill

Batch size 11 gallon (5.5+5.5, 50/50 split)

Grain bill:
20lbs 2 Row
2lbs 60L
2Lb Munich

I was thinking about cutting back on the 60L/Munich as low as 1.5lbs each, but I'm not really sure

Mashing 90 minutes at 153

My 1st runnings should come out to 1.084
Second runnings should end up 1.042

<edited, thanks Jesse/dkershner>
I was going to mash with 8 to 9+ gallons of water and when I drained my first runnings I was going to stop at 6.5 gallons and start my Big's boil.
<edit>

Then I would drain the remainder (if any) into my second pot and figure out how much more I need for my Small.

As for the hops, I was thinking about running my untested IIPA hop schedule since it shares the OG and a similar grain bill

1oz Columbus 14% at 60
1oz Nugget 13% at 60
1oz Centennial 8.5% at 15
1oz Nugget at 15
1oz Columbus at 15
1oz Centennial at 5
1oz Columbus at 5
1oz Amarillo DH
1oz Centenial DH

For the Small, I'll just use some basic APA hop bill, nothing crazy, actually probably pretty plain, maybe even something mostly late additions.

Both will probably use US05 since I don't feel like making 2 starters for my WLP001, but I could be convinced otherwise (due to the 1.084).

Is there anything in particular that I should know about trying out a partigyle recipe?

<edit> holy **** I suck. I wrote this up real fast when I had a few minutes. I meant that I meant to collect 6.5 gallons if I boil for 60 and 7 gallons if I boil for 90. So I will need to mash with more, oops. </edit>

So for your IIPA, your preboil volume will be 5.5g?? what about boil off?

This, and don't forget about the grain soaking up the water. You probably would only have about 5.5g in the MLT.

Damn, I wrote that up real fast. Yeah, I meant that I wanted to collect 6.5-7 gallons (depending on a 60 or 90 minute boil), so I will need to mash with more water. probably closer to 8 or 9 gallons of water, I guess.

I need to re figure out my grain absorption rate, or go with what I have listed in Beersmith already, because I'm usually close with that.

Do you fly or batch sparge? The volume thing is pretty easy to split up if you fly sparge, and needs to be calculated in advance if you batch sparge. I think it is OK to sparge some though. On my first partigyle attempt, coming up in a week, I am doing a 10gal Barleywine followed by a 5gal Brown. I will have to sparge some of the barleywine, and the brown will be basically all sparge.

I batch sparge. Is there any problem in making this batch like I would any other batch and just collecting enough wort in my 1st pot for a pre boil volume and then a second pot with the remaining sparge? Are the second runnings less fermentable?

I am certainly no authority on the topic, but I see no reason why the sparge runnings would be any less fermentable, just weaker (less sugar).

I also think that the way commercial breweries run their Mash Tuns (max capacity), their partigyle 2nd beers are likely all sparge too. Their 3rd have to be.

I would have some pale DME on hand in case the second runnings are looking weaker, or if you have to top up on the 2nd brew.

1. What is the desired OG for the IIPA? 1.084? (and that's 11g batch size)
2. What is the desired OG for the APA? and what's the batch size? 5.5g?
3. What is your expected efficiency for the IIPA? 60%?

Question relating to partigyle brewing: I did this one, my friend and I were both brewing some big beers, and we each did a second sparge and took those runnings and some LME into an extra kettle. We took the late addition hops from his and my boils (5 min?) and threw them into the weaker wort for bittering hops. we did some taste samples along the way to guesstimate balance and added a little more fresh hops. The beer came out pretty good, and it was a good experiment in recycling but I wonder how effective the used hops were.
