Efficiency ?

[SuperBroo]

Hi All,

Sorry if this is being a bit lazy, but I would like to know what my efficiency was using the details below.
If I apply the figures to the brew i just made last night, it will make a lot more sense for me. So many numbers in this craft if you want to get things right, but I am learning I think

I did a 90 minute boil, should have only done 60 as i lost 16% in the boil, but thats my first lesson learned, no harm done I dont think.

anyway, this was my recipe, Which is basically Docs JSGA All grain...

2.73 Kg Pale malt.
0.91 Kg Munich malt.
0.91Kg Wheat malt.
0.27 Kg Caramalt (Crystal 50).
Mash 1 Hr at 64.5 Degrees (wanted 67, maybe get it right next time, I learnt what I did wrong).

All Amarillo hops...
25g @ 60 mins.
15g @ 20 mins.
20g @ 5 mins.

Preboil volume 28.3 L
Preboil gravitry 1.033 @ 20 degrees.
90 minute boil (60 next time).
Post boil volume 21 L.
Post Chill volume 21 L.
Trub loss 3 L.
Topped up to 20.3 Litres in fermeter.
OG 1.045 @ 20 degrees.

Pitched 1 packet US05, (rehydrated for 1 Hr beforehand).


Please feel free to comment on any wrongdoings, and any advice is appreciated.

Cheers,
Chris

59.3%

Basically my recipe? It is my recipe

If you enter the numbers into beersmith it will tell you your efficiency.

Yes, its yours Doc, But I think I may have changed a bit of hops maybe, anyway, its sincerely appreciated mate...


59%, thats a bit useless isnt it ?

cheers,

My first few were low 60s and i soon peaked at 70% which is where i am now, 78 AGs later. A mashout helps as well as ensuring your sparge water keep the grain bed at 76-78C.

The % is not important, consistency is.

I am sure you will increase in the next few batches.

A 90 min boil is what i do, you just sparge a few extra litres to allow for the extra evaporation. You might be able to turn the burner down - it needs to be a rolling boil, not violent but more than a gentle simmer. This might reduce your evaporation rate down. 16% is high but not unheard of. I get 12%.

thanks Doc,

I also think maybe my grind was a bit coarse, brand new crankandstein mill.

thanks again, it puts me at ease a bit

Last 2 brews 76 and 75 %, so now thats hopefully where they will settle down,

yes, consistency is the key...

thanks Doc..
