I'm having a hard time working out what my efficiency was because of the addition of honey. I did my first all grain and as far as I can tell I think I did well.

Here is the recipe(please note it was 4 gallons final volume as intended):
http://hopville.com/recipe/1442295/b...rain-4-gallons

I measured the OG pre boil and pre honey at 1.025

Then before pouring into the primary(after boil) I was at 1.050 with the addition of honey.

So when do I calculate efficiency without accounting for the honey addition?


I also learned that I should just pour the honey straight into the primary(instead of at flame out) because I did end up with what seemed like a bit of it mixed in with the trub when I cleaned my pot. It was a lot jumping into my first all grain with my own recipe and BIAB setup. Also lit my bag on fire a bit and broke a candy thermometer. Fun day.

You calculate it using that 1.025 reading for whatever volume you had pre-boil.

Knowing the amount is 1.6 gallons, what formula or online calculator do I use?

The March-April issue of BYO magazine covered this exact subject, including all the calcs and adding some maltodextrine as the honey tends to dry the beer out.

Can anyone help me with the initial question? I keep googling things and not getting a real answer. Thanks

Does that look like I used it correctly? I'd be amazed if I had an 88% efficiency on my first BIAB.

You boiled off 2.8 gallons? If 6.8 is actually the correct volume, then yes you're using the tool properly.

Well I lost 2.8 gallons to the grains, boil off, and trub. When is the correct time to measure the wort for efficiency? Before the boil or after?
