Biab info needed

Hi , im doing my first biab and just need to work out water quantities. Plan on a citra smash , doing 23 lt batch in a gas keggle. Not signed up to beersmith or similar sites yet,.
Any help appreciated

Beersmith would be a good place to start what's your grain and hop weights?
Pobs resident Biab expert and if memory serves he normally goes 32-33l spending on boil off 5-6 litres and trub at bottom 3-4l

This is how I calculate:
Initial Volume =
         23L          Fermenter Target Volume
    +    2L          Kettle Loss (what's left behind in the kettle after you've filled the fermenter)
    +    0.5L     Hose Loss (wort left behind in hoses: easy to forget)
    +    1L        Cooling Shrinkage (Water gets denser as it gets colder: 100L @ 100C = 96L @ 20C)
    +    4.5L     Boil-Off (usually 10-15%)
    +    5L         Grain Absorption (Grain absorbs water: allow about 1Litre per kg of grain. Assume 5kg in this case.)
Total = 36L required at start to end up with 23L in the fermenter.


You will need to estimate/guess what your losses will be, considering your equipment. First few times is all about measuring these losses. Record everything carefully, and that will help you dial in your process.
Hope that helps and good luck with the brew.

Beersmith has a set up configuration to help you plug in all those numbers and will let you know automatically what water vols are including thermal dynamics from keg.

I'd highly recommend BeerSmith. As CH says, it will do all the calculations for you. You just have to enter your equipment losses in your equipment profile. You can download it free for a 30-day trial, and you can get a discount buying it as an NHC member (best tenner I ever spent).

Didn't somebody post here recently buying it in Aus$ or some other kinda deal?

[SkiBeagle]

Yeah, there was. Though I ended up buying in US$ and using the NHC discount. Cost me $23 (€21.50). Well worth it. And not just for calcs, but recipe and ingredient management is great also.

I got it from here for $19/£10 but they seem to be offline until Monday.

If you're any way comfortable with a spreadsheet then BIABrewer.info will give access to their calculator for free once you sign up to their forum. I've only used it once so far but I found it very accurate. Lots of great info for biab as well.

Thanks for replies. Something like thisi is what I was after for now.
Just need to Nick the wife's credit card for beersmith😏😏!!!

Start with free brewmate.
Been using it for some time.

Will second this. Use the biabacus excrl spreadsheet. Find it very good, once you find your way around it. Has been spot on in terms of volumes, expected gravities, scaling etc.

(Sad to say, it is tge fact that is a nice bit of a spreadsheet, that appeals to me also!)

Before i got beersmith I used http://biabcalculator.com, its very straight forward
