Ok I've got an 100 litre keg so i was thinking off doing a lentil wash if my calculations are correct if not then correct me so hear goes 80 litres of water ,1600g of red lentils 20kg of sugar and 320g of Allison's​ baker's yeast .

Assuming that you have a 100l fermenter , or enough smaller.

IMO your sugar and water are close to what I would do, I might up the sugar to 24 kg...
Your yeast is kind of high, I use 50g in 25 litres.
And I have recently had no ill effect cutting back the lentils to 100g/25 litres.
That's a cheaper wash that seems to work just as fast.
Just sayin'.

Hi Robbo

I would keep the wash to 80litres, to give a little head space in the boiler, I use a 50 litre keg and never charge it with more than 40 litres.

It’s also gonna take a while to heat up, I would use 16 kg of sugar for 80 litres, which is inline with the amount you already suggested for a larger wash.

A problem you might have is getting the finished wash into the boiler, you’ll need some kind of pump, as it’ll be too heavy to move or lift by hand, I can just about safely manoeuvre and lift my 40 litre ones, and even then, only by following proper manual handling techniques so I don’t put my back out!

Ok Robert i will go with that.

I was thinking of doing it in batches because i have a t500 so would do in 25 litre batches.

I am now confused.
Are you planning on using your 100 litre keg to ferment in?
And distill with a T500?
And the mention of batches now confuses me more from your OP.
But, hey, questions are questions.
And someone here may have the answers

Robert.

The keg I'm using has been made into a fermentation keg just to clear any confusion.

Yes Robert just getting giddy with all this

I see no problem with a big ferment and numerous distillations.
I will stick with the first advise that I posted.
Good luck with the brew, ferment and distillation.

Robert.

Boy you have had a sugar rush. Lol. I your comment.

Couple of things spring to mind. Caravan "whale" pumps on the end of ½ inch hose are very good & cheap.

If there is going to be a delay between stilling sessions, you might want to consider keeping the wash going with a few spoons full of sugar.

My thinking...
By the time you get to the last (fourth) run then it's a big airspace in the fermenter. If this is 4 days it probably doesn't matter. If it is 4 weeks it will get into trouble.
A finished wash is a sugar wine. Nothing more, nothing less. Would you expect a bottle of wine that's been open for four weeks to be ok? No.
A bit if extra sugar will keep the wash slightly active & producing co2 which will provide a protective blanket on top of the wash.

Word of caution. Where are to doing this? Co2 in quality can kill. Keep well ventilated and away from pets/children.

Ps. You don't need quite that much yeast. Use 2 tins. There is also a benefit if you rehydrate it properly. It makes a difference

Once it's fermented and cleared I'm looking at doing it over 4 days and collect my neutral then putting back through my still and collecting and making cuts.

I run 3x25ltr washes at a time. Just find it easier
to move if needed and as Mash said keeps it fresh.
Also if you do have a problem with one wash, you
still(hopefully) have two other healthy washes to
still.

Ok thanks for the info.

@Robbo. I am running 90 L washes, 22kg dark brown sugar, 150 gr yeast. You have flexibiliy with a sugar wash. Find what works for you and run with that.
