Hi Jayse,
your method sounds interesting and a time saver, the only problem is, I don't follow how you do it.
If it's not too much trouble when you have the time could you post your method step by step as I am converting over to a three 50lt keg system and I would'nt mind giving your metod a go if my eff does'nt drop to much. also what is "boil start gravity"??
sorry to be a pain

Hi Andrew,
The method is not all that different really, you conduct your mash as usuall then when the mash is finished and you have all your sparge water ready to go you add it to all to the mash in one heap as you would for a batch sparge only with this method you add it all before you drain out the first runnings.
So say a 5 kg brew you have mashed with 3 litres of water per kilo you work out how much sparge water you need(you know you'll get 9.5L out of the mash) to reach your boil start volume as you would ussually. Mines 32 litres so i'll need around 22.5 litres of sparge water to get up to that volume in the kettle.
All of this water is added to the tun at the end of the mash BEFORE i set the tap and start the lauter.
The boil start gravity i mentioned is the gravity at the start of the boil in my case the gravity at 32litres in the kettle.
Steps
1. mash as per normal
2. get sparge water ready
3. when mash is finished add all the sparge water in one hit before draining the first runnings.
4. mix up very very well
5. recycle
6. set tap and take gravity reading it should be the gravity you predicted for the boil start
7. boil it and add two shovels full of hops
(optional step)
The temp of the water you have for the infusion you can calculate with software to give you a step infusion up to 78c in the tun, The temp is ussually around 85-90c for this 22 odd litres of water. That brings the mash up to around 78c.
What you end up with in the tun is the extact wort your going to boil ie the same gravity and the same volume plus a few litres that will remain in the grain.
It is a unreal way to brew i think not just because it saves a hell of a lot of time over doing a fly sparge or a bit of time over doing a normal batch sparge.
A real benefit i have found is the mouthfeel on the beer and how clean they come up is awesome, In the mouth the tongue is not distracted by any harsh or tingley like(for the want of a better term) feel. The body and mouthfell are just perfect and you can really taste a really clean beer and pick all the flavours perfectly.
Before doing this i had great clean beers but i have found my beers are just rocking now.
I'll try and come up with a better discription for the mouthfell iam talking about here when its not 3am in the morning and iam not winding down from a gig from hell.
Anyway good luck with it guys, i bet after everyone gives it ago for the first time you'll all be converted. Iam not sure where all this lower effiency bull dust is coming from in some articles on the subject, maybe if your getting insanely good effiency like 90% you won't get that with this method, but it is easy to get 75% no probs at all.
In the end it saves time and effort but best of all makes unreall beer because you don't go anywhere near extracting anything from the grain you don't want.
Sorry for the preach on this method, it is sunday after all.
Hopefully the way i described the process make sense.
Happy brewing.
Jayse
