I got on to this idea after reading this thread lead me to the idea of doing a partigyle DIPA and re-using the late addition hops from the big beer to hop the small beer(s).

I started working up a 2 batch grain bill, but I feel the small beer is too small to utilize the amount of hops that will be left over from the first batch even if they have been partially utilized. So now I'm thinking it needs to be a 3 run-off event.

I'll post back with a recipe draft when I have one.

+1. Ive only done 4 all-grain but the partigyle aspect just fascinates the crap out of me. Were you thinking like DIPA for big and APA for small?

I've been on a partigyle kick lately. I am doing a doppelbock/alt this winter and drew up the recipe for a rye saison/rye pale ale partigyle as well, which I may revisit this spring.

The big beer is definitely going to be a DIPA. I've been fiddling around with grain bills looking at different split batch scenarios. I'm having a hard time coming up with the gravity ranges that I want. I think I'm going to have to sit down and do some calculations and settle on differing batch sizes for each beer in order to get closer to my desired gravity.

The goal is to make a DIPA that is in line with a recipe I already have and then get 1 or 2 more batches of pale ale of some variety that utilize the leftover hops from the big beer. I think it will end up being a DIPA and an APA. I was thinking DIPA, APA, Bitter initially, but it seems like, in order to get a reasonable Bitter out of the third runnings would make the big beer a Barleywine realistically.

When you say using leftover hops, do you mean taking hops in say, knockout, and using those as the 60M addition for the next batch?

FWIW, you can also perform a mini-mash if you want. Mash some specialty grains that you'd want in one beer but not in the other with a handful of six row, then add that to the boil.

Yup. The hypothesis is that if you use a huge amount of late addition whole hops (say 8oz or so at <20mins) that they will still have plenty of unutilized acids and oils available to use in the next batch. Risky business to say the least, but an interesting experiment.

I may be misunderstanding, but I don't see why you think it is "risky" (?) It seems smart to me.

In researching partigyles I seem to recall lots of breweries doing that. {*yes, found it: http://www.brewingtechniques.com/library/backissues/issue2.2/mosher.html

If it were me, I'd use whole leaf hops, just because the pellet sludge in the bottom of my BK seems hard to work with.

Great article. I'm using the equations Mosher discusses to figure out how to split the batch. I like that he gives you the method you need to work backwards from your desired gravities and volumes to calculate the master batch gravity. I think it will be key in doing this the way I have in mind. I really don't want to fuss with dilution/extra long boils.

In theory it shouldn't be that hard to estimate the hop utilization from the first batch and be able to at least guestimate how bitter the small beer will be. The 'risky' comment is just that it is an experiment and I won't be sure what kind of hop character to expect out of the small beer. Especially since all the hops will be mixed together coming out of the kettle. On the other hand, I find it's pretty hard to make truly bad beer so...

Absolutely going to be all whole hops. Even though I can't think of a reason why using the sludge wouldn't work just the same if it's coming out of a hop bag, it just seems gross. Plus I have a couple pounds of whole hops from last year that I need to use.

Man, experiments are where it is at. I say go for it and let us know how it all turns out. I'm pretty stoked about the whole partyguile idea and I'd love to hear of your results. I mean what's the worst case? You still end up with 2 or 3 tasty beers whether they are what you planned or not?
