My daughter has lent me a very nice 20 litre stock pot so I'll try using it for my first BIAB.
I want to get 20-21 litres in the fermenter for a 18 litre keg. I was also going to no-chill it. I plug the figures in to the calculator and I get 16.7 litres in to the cube. It then says to add the extra water to the fermenter to make it up to 21 litres. Why wouldn't you add boiling water to the cube and make sure you have no head space?
Cheers

Well, I suppose you could do that, its just that its usually far easier to add cold water to the fermenter
You can squeeze the cube to displace a lot of the air, and unless its very empty it should be okay, and even if there is some headspace, the jury is out if that actually makes a difference or not

As per stux, no major issues with that method Steve, it may be more convenient and energy efficient to just add cold water though.
One possible problem might be the calculation of the wort SG (with stux's excellent calculator!) as opposed to actually measuring it and then knowing by how much to dilute- unless you're able to reliably predict efficiency then you may not reach the desired OG in the fermenter. That's one of the benefits of the Maxi-BIAB method in the guide, you are able to hit OG in the fermenter precisely, albeit at the expense of variable volume of course.
I've not been overly concerned with some head space in the cube to be honest, I don't think it is the huge drama it is often made out to be. However these days I mostly chill in- kettle anyway, so its now moot as far as my own method is concerned.

Stux and Ralph,
Thanks for the info. Think I will not bother with the head space and follow the "instructions as directed"
Now to work out what to brew
Cheers
Steve
