Efficiency Readings

[tribalfish]

Hi all,

I have done my first ag brew via the biab method this morning. Everything went really well except I didn't remember to take volume and sg readings until 10 mins into the boil.(realised at first hop addition!)
So I shut down the burner and took a sample to test later when cooled, and also measured my volume, then cranked her back up and continued as normal.
Obviously liquid expands when hot. So I was wondering is there still a way of calculating efficiency from a near boiling temp?

Thanks in advance Tribal.

One of those handy rule of thumb numbers
There will be a 4% difference between the volume of boiling and the same wort cooled to 20C.

So if you measured 32 L at 100 C or close to, you would have (32 X 0.96) = 30.72 L if it was cooled to the temperature the hydrometer should be calibrated to.

Hope that helps with the calcs

Thanks MHB. :icon_cheers:

Pumps up my efficiency a fair bit.
So many little things to remember in a relativley short period of time.
Made plenty of notes on things I could have done better and equipment I need to purchase.
Can't wait for the next brewday and ofcourse the tasting! :icon_drunk:
