Getting the most out of my grain

[Wicks]

I've been doing quite a few bigger beers of around 7-10% this means lots of Pale Malt. Been doing research regarding using the malt to try and get a lesser "small beer" out of the same mash. My current method is to BIAB mash in one pot (first runnings) and then I do a dunk sparge in a larger boil pot (sort of a second runnings).
I'm thinking of mashing and grabbing the first runnings for the Strong Beer and then dunking the bag in a new batch of water for some second and maybe some third runnings if I have enough pots. Take a Hydro reading of the second runnings and increase with DME as required for the "small beer". Thinking of something about 4%. I could even allow a little of the first runnings into the second batch to give it some additional body. I realise taking a pre boil Hydro reading I need to account for the rise in gravity due to boil off. Also I do have 2 fermenting vessels and two large wok burners on my cooker so all good there.

I did read of someone adding extra malt to the initial batch to allow more first running wort to be added to the second batch, started to get a little complicated then. Sort of defeats the point for me trying to make the most of the first load of malt.

Anyone tried anything like this, have any tips/pointers?

I have just read about this in the river cottage handbook booze and by all accounts you should get around 3.5% as is but with DME should knock it up a bit to 4.
I have never tried it but the theory is sound

sounds like a parti gyle to me

That's the term apparently some breweries do it for extra taps.

Isn’t that how Fullers make London Pride and ESB?
