Double A side this one, I'm attempting my partigyle beer! Difficult one to manage this one as I can only partly use beersmith. The idea is that I make one beer from the first mash - no sparge. 13.2kg of grain - tried to get 40 ltrs of water into the tun but with all that grain I could only get in 35. This will be my 'Big Beer'.

10.00 kg Pale Malt (2 Row)
2.00 kg Munich Malt
1.00 kg Wheat Malt
0.20 kg Roasted Barley
35.00 gm Chinook [12.70 %] (60 min)
35.00 gm Cascade [7.60 %] (30 min)
30.00 gm Challenger [7.60 %] (0 min)
1.32 tsp Irish Moss (Boil 15.0 min)
1 Pkgs SafAle English Ale Yeast #S-04

Did the first mash overnight - went in at 9.30pm and stayed in until 5.30 in the morning. Mash temp was 68C and AMAZINGLY the whole mash only lost 1.1C. I couldn't believe it!

The dough-in .. nearly broke my arms this one!


All tucked up safely for the night


Lost 1.1 C in an 8 hour mash


First runnings of the Big Beer .. recirculated








OK .. so Big Beer in boiler.. small beer mash time!


Into boil goes the cooler .. 15 mins from end of boil








Back to SB (small beer): First runnings for recirculation:


Quick pic of the sparge - 7.5 ltrs


Look ma .. twins!


I didn't bother to take so many pics of the SB as the whole process was identical - including hops, timing and yeast.

SG for BB = 1090. I added liquor in at the start of the boil and then again later to drop the SG now to 1075. Don't want too strong a beer - also, I couldn't get all the liquor into the tun that I wanted as it wouldn't fit, I was 5 ltrs short.
SG for the SB is 1065, pretty good really, but once again, I think this is more to do with the fact that not enough liquor went into the mash for the BB.

All in all, 21 ltrs for the BB and 23 for the SB, 8 hours - 7 yesterday and 1 the night before - not a bad brew. Have a good feeling about this one .. although I'm not sure it's something I want to do too often! Came home this lunchtime to see that the BB had blown the lid off. Thank F the missus didn't see it before I had the chance to clean up. Smells fantastic though!

Happy man!

Looking good nice set of pics

[Tony01]

Cheers pdtnc! Smell from these is wonderful .. getting impatient already!

Nice one Tony01.

That's inspiration for me one day. SB looked like a really nice dark colour too.

Did you 'mash' the second one at all or was it basically just sparging?

[malc]

Looking good Tony01
do you recirculate until it runs clear? i've not done that before does it help in having a clearer beer in the end?
cheers

Hey beerkiss, yes it was basically just a sparge, just left it sit for about 30 mins

Hey malc, yes more or less, usually 3 or 4 ltrs is enough to get the bits filtered back through the grain

Excellent stuff. I'm impressed at the SG for the small beer - particularly after the Big beer came through so well - all told an impressive mash.

Can I ask.. the hopping amounts and schedule during the boil... was this identical to the big beer... so you're aiming for an identical IBU/bittering profile for the lighter beer?

[Tony01]

Hi bellebouche

Cheers!

Yup, everything was identical, boil time, hops and hopping schedule.

Brewed this on Monday morning and fermentation is finished in the big beer and looks like the small beer finished overnight too. Big drop in temp here this week (London) so have stopped worrying about high fermentation temps! Think I'll rack into secondary today and dry hop with 20g challenger in each. Probably leave that in there then until next weekend.

I've (only once) attempted a parti-gyle... and it was something of an accident/afterthought. I'd made a mash for a Scottish 80/- did my brewday as normal and when I came to chuck the spent grains to the chickens noticed a thick dark very sweet wort still available from the tun when I opened the tap. So, taking a flyer that there might be a baby brew in there still I ran 6 litres of water from three part-boiled kettles through the (by then 7 hrs old mash) and got a gallon of 1050 wort out of it after a one hour boil.

It was unrecognisable from the original brew... and I dry hopped it to in the fv for a week after the fermentation had stopped and it made an excellent mid-strength bitter.

Waste not, want not!

How big is your mash tun vessel?

I have the 40l thermobox and have been wondering for a while just how big a beer I could make. If necessary I would do two mashes one after the other and collate first and second runnings from each to do the partigyle.

[Tony01]

got a gallon of 1050 wort out of it after a one hour boil.

Excellent... be a great way of testing hop combinations too!

How big is your mash tun?

The tun holds 50ltrs but with 13.2kg of grain in there, the most liquor I could get in was 35ltrs. I think that effected the OG of the big beer quite a bit - and therefore allowing a higher OG in the small beer.

To be honest, my main restriction was having a 25ltr boiler, or I would not have attempted the partigyle. Ever since doing this on Monday, I have regretted not attempting a 3rd beer - as the OG of the small beer was considerably higher than I had expected - again, due to not having enough liquor in the initial mash. I had expected the big beer to come out somewhere around 1095. If you have a big enough boiler you could easily combine 2 mashes ... or a big enough FV with two separate boils!

Still .. I'm happy with the two that I have got, expect the big beer to be drinkable somewhere around end of october and the small around beginning of october... well, that's when I'll be dipping in!

[bellebouche]

Could always be worth a flush through with a kettle full of hot/ 80c water to rinse through enough for a starter wort for bringing on a yeast - freeze it and then reboil/sterilse ahead of your next brew.

[Tony01]

Just thought I'd give you an update on this...

Bottled the small beer this evening. Tastes absolutely bloody wonderful .. full of rich malty goodness

Now I'm pretty sure all my figures are correct and I've checked twice at least... the small beer went into the FV at 22C and after a slight temperature correction came out at 1065. It's now at 1005... that makes the small beer smack on 8% I must admit it does taste strong

Lesson 1: If I do this again I'm using much less grain!

Bottling the big beer tomorrow - it fermented for 2 days longer than the small beer... I'll report back again if I'm able to see clearly after sampling it.

Hi Tony!

Sorry to 'hijack' your brewday thread...

Where did you find out how to do the partigyle calculations?

I'd like to do athe folowing and a partigyle appeals to me...

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)

What do you think? any pointers?



Cheers
