Was reading about some funky Saisons and stumbled upon one using sweet potato as adjunct. I decided the caramel/toffee flavours of heavily roasted sweet potato would go well in a porter so i couldn't help myself!

i roasted 1kg of sweet potato whole for close to 2 hours at 180deg. They ended up all jammy. Pureed in the food processor once cool and straight into the mash. The mash has some mild sweet potato charter in it (kind of like maple syrup and toffee). hoping it carries through into the beer. unsure what gravity contribution it will lend. I'm assuming something like pumpkin does. 1.030 SG or there abouts.

Notes:

dilute post boil to 36IBU @ 1.055 @ 40L

Thinking of secondary fermenting 1/2 batch on some WLP655 Belgian sour mix.
 
Tripel
2kg gladfield vienna
5 kg glad pils
125g each dingemans biscuit & aromatic.

Hallertauer mittelfruh and styrians to 40 ibu with some at 10 and whirlpool.

Some decoctions and steps, 200g white sugar to boil, 800 added in increments post active ferment.
1 pack wy 1388 in a 6L active starter with another fresh pack added at the same time.

Start fermentation around 16, allow to rise to low 20s after 3-4 days, 3 weeks minimum cold conditioning.

Some calcium chloride and lactic acid to mash, lactic to sparge water, cal chloride to boil.
 
Looks great, mants!
(I'm not sure about you, Fourstar. Sweet potato?! I think you have issues ... though maple syrup & toffee sounds fantastic [emoji6])

Hey manticle, what was your Vol, OG & est. FG?
6L starter plus a 2nd pack?! Wow, that's a lot of yeast! I hoped you brewed something tasty for your starter, given its a mini batch brew all by itself.
You don't use any calc sulf to affect your 40 ibu's of hops?
I know it's mainly/totally a malt driven beer, I just thought a bit of CaSO4 might do favorable things to the bitterness? No?
 
At 40 ibu and 9% I want a very soft beer to balance. I did put about 1g of caso4 in the mash but I want smooth, gentle bittering and good subtle maltiness. Also fwh half the bittering addition.

OG calc I can't remember - probably around 1070 or so without the sugar. Maybe a tad more. Just bringing it to the boil now.

Starter will be from the same wort which is how I usually do them. No chill, pitch the whole starter when active. Big Belgians need a good whack of yeast, otherwise they taste like bad home brew (tasted a commercial locally brewed belgian pale last night that was exactly that).
Tripel for me is gentle, smooth, complex, aromatic and beguiling.

FG aim is 1010-1012.

90 min boil.

just thrown the WLP007 on it now. Out of the chiller the wort didn't taste much (if any) different to a standard porter. i ended up with an OG of 1.058 so my extract assumptions wasn't too far off.

im really interested to get my hands on a bottle of this, the bruery make some delicious beers.: http://www.thebruery.com/beer/autumn-maple/?category=seasonal

sounds like a sweet potato version of a pumpkin ale or the brett version at their sister brewery would be delightful! :icon_drool2:

I haven't done any cereal mashes yet, but I was under the impression it was not required with flaked or torrified ingredients...

What method do you use?

BYO said it's a good method, so I just went ahead with it
I threw the corn and 500g of the malt into a 20L Big W pot with 7-8L of the main mash water (I BIAB), brought to 70C and rested for 5 minutes
Then brought it to a boil for 30 minutes and I'm just about to add it to the main mash
I'm thinking 500g of malt may have been too much, so I'll add another 200-300g to the mash to make up for lost sugaz (guessing they wouldn't have converted properly before it was brought to a boil)
 
I have a Red X ale fermenting currently with Dry English Ale 007 and plan to use the yeast cake with a YOB inspired no chill ridiculously cube hopped only beer :beerbang:

My usual black IPA has base malt, Vienna, light crystal, med crystal, flaked oats, melanoidan and 10% choc wheat for the mash out colour. for this no chill I'm aiming to simplify the malt bill.

OG 1.065
FG 1.013
ABV 6.8
IBU 90 ( brewers friend calculated this - will see by taste what its like )
EBC 70
Vol 20L

80% Pilsner
5% Carapils
5% Dextrose

Mashed @ 66c for 60mins

adding 5% Carafa S 3 & 5% Chocolate Wheat @ mashout for 20mins - recirc wort to extract the colour.

boil 60mins - no hop additions ( im so wanting to add some columbus at 60mins for 25ibu but this is a cube hop experiment)

100g - CITRA into the cube

Fermented on 007

Can anyone tell, when i use teh yeast cake should I pour it aggressively to aerate and then hit it with O2 or add gently and then hit with O2 ??
 
just swirl the yeast cake from the previous brew to mix it up with the beer layer above it and pitch a couple of cups of it. I wouldn't dump it on the yeast cake. you'll just double the trub in your next brew.

Yep you don't need a cereal mash with flaked corn as it has already been gelatinised. No harm done though, just unnecessary.

well, I also should have mentioned, it's cracked stock feed corn not flaked corn (no LHBS within 140kays of me)
thought it was best to do the cereal mash just in case

LRG1 I am interested in how these seperate ferments turn out, almost went with one of these yeasts for my stout but went us05 instead... and wore pants the whole time

It should be fine. Just testing (again) the limits of my system. Last time I did this, I knocked out a RIS and an IPA in the same mash, by separating the spec malts and steeping them separately and boiling in separate pots on the stove.

This time, I have a bag (just because it was easy at the time), and I'm whacking all the mash in a 50L esky, step mash and separate ferment, one on existing yeast, the other on a new packet (which I have never tried before).

Pants or no pants, I like to live dangerously.

is the additional trub the only concern?

Can I just swirl and then open the tap on the FV to empty out most of it and then pitch the new wort?

Absolutely, when repitching that's what I've done and it has always worked out well. Pour aggressive, hit with some 02 and it'll start like nothing else.

Ps- Additional trub and massive over pitch are the concerns with using the entire yeast cake.

As far as I've read and done, the aim in reusing yeast is to get as much of the good healthy stuff and as little of the dead cells, hop debris etc that makes up the rest of the crap at the bottom of the FV. If you're happy you're achieving that, all good. For me, the extra time washing the yeast is usually worth it. YMMV
