OG Calculation

[olstones]

When I calculate my estimated OG, which amount of water do I use as the denominator: the boil size (e.g. 6.5 gal) or the final size (e.g. 5.5 gal)?

I am still unsure about my EE% but still makes quite a difference

Thanks

OG is the density of the wort prior to pitching the yeast, so use the post-boil volume.

And don't forget to convert your units using a tool like www.brewersfriend.com As you may know, the sugars are more soluble in solution when it is hotter so, your gravity will be changing as the temperature does. But yeah, use the one right before pitching.
