Hi,

I would like to know the differents ways to calculate the volume of the wort in your pot after grain absorbtion and/or after boiling.

Example, let's say I want to BIAB a batch and should target a 7.4 gal Pre-boil volume.

I estimate the grain absorbsion to be (example) 1.1 gal overall. So I'm starting with 8.5 strike volume for the mash. How do you determine if you really have 7.4 gal of wort in your pot before starting the boil (after the mash)?

I'm thinking of marking a stirring spoon on every 0.5 gal, it will give me a rough idea of the volume of the wort in the pot ? Is there a better way to do it ?

Thank you.

You can make a stick like you mentioned. You could also have a sight glass installed on your pot.

A marked stick will work. This BIAB calc. inputs kettle dia. and gives you wort volumes measured from the top of the kettle.

I use the measuring stick method. I have mine marked in 1 gallon increments and just guess on the fractions of a gallon.

I filled my kettle up with measured water volumes on the first day and wrote the numbers at the correct spot on the outside of the kettle with permanent marker.

Imagine how cool brewing will be once they've perfected transparent metal.

I opted for an hybrid of both method you mentionned, I marked an unused racking tube, put it in wort and just put the thumbs on the other end to keep wort level in the tube. I can take a reading this way.

Thanks to all for your suggestions.
