Brew House Efficiency

I’m trying to workout my brew house efficiency, and wonder if the “possible” extract figures I’m using are correct.

They are as follows-:
Pale malt, wheat malt, flaked barley, flaked maize etc – 300 degs per Kg per Ltr.
Crystal malt – 240 degs per Kg per Ltr.
Granulated sugar – 360 degs per Kg per Ltr.

Any corrections will be gratefully received.

My current average extract using the above figures is 85%.

 

Oh well, some you win and some you lose!

Sorry eric, can't help you.
I would love to know myself what the accepted figures are.
Does anybody else have a clue?

I don't have my books where I am - you could try the recipe calculator on this page to work it out. They seem correct from memory though, but I think I've seen 370 used for sugar.

Also your extract from sugar will be 100% which may be why you think your efficiency is high. But 85% is achievable so it might not be that.

 

Thanks ano, never thought of the calculator.
Due to my "mash tun" limitations, I use 1 lb sugar with 7.5 lbs malt.
This just boosts the ABV a little.
I take your point, it needs subtracting from my calculations!

Damn, this drops my BHE down to 76% :shock:

That isn't out of the ordinary.

Also by trying to use to recipe calculator you add a recipe to the database, so don't forget to delete it if it's just for playing.
