Don't worry have a homebrew. It'll turn out fine whatever you do.

What's the difference between the two?

Hey Nick. I think you might want to read the thread "BIAB brewing (with pics)". It should answer a lot of your questions.

Here's what I'd do if I were you. First, read that thread I mentioned. Then I'd probably use about 15 litres for strike water, mash in, then sparge to hit about 15.5 litres pre boil volume. Boil down to 11.5 litres, transfer 10.5 litres to the fermenter, and that should get you about 10 litres into the bottles or keg.

Why is BIAB different in terms of water quantities rather than a conventional mash tun?

I'd still be using 15.5 litres despite only have 1.8kg grain for my mash, right?! My kettle holds 12 litres but my cool box holds 24. If I did it in the cool box (which I yet to be converted into a mash tun, hence the grain bag), how would I do a mash out or even the sparge?

Suggestions?

No mash out is required.

There's an infinite number of variations on sparging. You just need to find what works for you. All methods require that you remove the bag of grain from the mash. Sparging in BIAB serves the same purpose as other all grain methods; you're washing the grains to remove that last bit of fermentablas. Two methods commonly used are:

1. Dunk sparging in a separate bucket of water, sort of like you would steep a tea bag. Just take the bag out of the mash vessel, the tun in your case, and dip it into another bucket with some water in it. Move it up and down a few times and you're done.

2. Figure out some way to suspend the grain bag over your mash vessel and then pour sparge water over the grains. Some people use pulleys and ropes. I use the steamer basket my kettle came with and rest it over the kettle on a grate from my oven.

These are two generic descriptions, each with countless permutations. Like I said earlier, find the tweaks that make it work for you.

Now, concerning your kettle, you're gonna have a hard time with that small volume. The general rule of thumb I've heard is that your kettle should be about double the size of batch you want to make. I'm pretty new to BIAB, but I've found this to be accurate. If you're intent on using this 12 litre kettle for a 10 litre batch do some research on "maxi BIAB". Because 15.5 litres won't fit in your kettle you're going to have to add left over wort from your mash, which will either be sitting in your tun or dunk sparge bucket depending on the sparge method you used, as it gets boiled off in the kettle.

Hope all this is becoming clearer now. Personally, I researched BIAB for several months before I did my first batch. I read everything I could about all the different methods, figured out what I thought would work best for me, and gave it a go. Keep reading, keep asking, make a plan and execute it.

Good luck.

Thanks TexasWine, that was a really helpful response

A friend of mine has a 19 litre pot which I'm going to borrow.
