Partigyle - Porter and a mild? Feasability?

[Manx Guy]

Hi,

Thought I'd kcik this idea out there....

Not had a random one from me for a while...

I'm thinking of making another Porter(similar to Anchor Porter) near the end of December and I also planned to make a 'Maple Mild'

The thought then occured to me that the grists are similar enough to possibly do a partigyle...

The OG of the Porter recipe I have my eye on is ~1050 I'd like a brew length of 15-19L
The OG of the mild could be as low as 1035 as I'll be adding plenty of Maple syrup in secondary. Brewlength can be 4.5-6 litres (as its mainly anexperimental brew)

However I'm pretty clueless to be honest... Any one tried it ?

Where should I look for more info? I have the book designing great beers but it doesnt really give much of an Idea on partigyle

Or should I just forget it and do two seperate mashes following on from each other?

Cheers!

Hi BK!

No I didn't see it.. I did search partigyle tho'... honest !

Does look good doesn't it... I may Pm the poster and see if they have any advice...



Cheers mate!

No worries mate I struggle with the search too.

Besides, there isn't a post to cover everything which is why it's good to ask the question in a different way...

The plan looks fine in principle but what I'm not sure about is how you hit the SGs you want. Do any of the common brewing software progs cater for Partigyle? I guess you can treat the first one as "no sparge" and so get the SG reasonably close but the second one might be a bit of a lottery. I suppose you could sparge it for whatever you get and then adjust with the syrup. I'd say go for it. Focus on the big one and improvise on the small one. And keep notes on exactly what you do...

I knocked up a excel spreadsheet to do these calculations. You can download it at

You adjust the OG and volume you'd get as a normal single gyle beer. It then calculates what you'd get if you partigyled it a number of ways. Working backwards you then know the OG and volume you'd brew normally and use that to calculate your recipe. It's arse-backwards but seems to work.

Hi Steve!

Many thanks! I have had a quick look and it looks like just the thing I need...

I think I can get about 15 litres of OG1051 Porter and 11.5 litres of 1034 mild... Which will be fine as I plan to add maple syrup to secodary which will boost up the ABV a little, hopefully without too detrimental effect on mouthfeel.

So would I just use a grain bill to get me my 51 points then sparge to collect ~18-19 l of wort into the boiler for the porter then (remash?) and sparge to get another 15l of wort for the mild?

Cheers!

Guy, I'll be interested in finding out how this goes - i've been considering something similar for AG4. I want to experiment more with different hops and beer styles, but can really only squeeze in one brewday a month so doing a partigyle would give me opportunity to muck around a little bit with smaller batches.

Gents,

The Jamil Show on Fullers Pride says this beer is done partigyle with ESB so maybe the two shows are worth a listen for some tips...?

Not listened to it myself though...

Partigyle is not really much of a time saver unless you have two sets of boiling and cooling kit. If you can only boil and cool one batch at a time then you might as well mash and sparge a totally new beer whilst you are boiling and cooling the first. That would also give you more control over the two beers. I do quite like the concept of two beers from one mash though.

Boingy, yeah, that's a good point. still seems like it might save me some work, although perhaps not as much as i'd hoped
