Can Someone Check This Conversion For Me (AG to Extract)

[TriggerFingers]

Hey,

Can someone with beersmith double-check this for me really quickly?

Here is the AG Recipe and below it a suggestion conversion to extract:

OG 1.058
FG 1.012
6.0% ABV
~45 IBU

All grain, 75% brewhouse efficiency:

Grain Bill:
9# 2-row
1# Crystal 10
1# Crystal 20
.5# CaraPils

Mash 150*F for 75 min.

Hops:
.25oz Warrior 60
.25oz Horizon 60
.25oz Magnum 60
.5oz Cascade 30
.5oz Cascade 15
1oz Columbus/Tomahawk/Zeus 5
1oz Columbus/Tomahawk/Zeus (DH)

US-05 Cali Ale yeast


Now the recipe states that converting to extract everything else is the same (2# of Crystal!?)

Extract:

In place of the 9# of 2-row use 6.75# of Extra light DME. Steep Crystal 10, Crystal 20, and CaraPils at 155*F for 30 minutes. A full volume boil is best. If you must do a partial boil, do a late extract addition with 10 minutes left in the boil to ensure proper hop bitterness and color.


Is this correct for the target #'s?

Sounds about right. I'd use the wort from the steeping grains to boil the hops and then add the extract at flame out. I make sure the temp doesn't drop below 180 when I add the extract and hold it there for a few minutes. 5 minutes at 180 is plenty to sanitize the extract without having to boil it.

Thanks,

So how do I convert the All-Grain to Extract to get similar #'s to the original? The original recipe is more of a session IPA that I am going for....

I used the same calculator but don't have the program to translate All Grain to Extract. Can anyone with beer smith please convert it for me?

I overlooked that you specified DME. 6.75 lbs would be correct for LME. In most cases you could probably just sub in .62 lbs DME or .75 lbs LME for every pound of base malt. When it comes to Munich or Wheat extract you have to remember those generally are blended with 50% 2-row.

Ray,

The extract is not what I am concerned about. Its the 2# of Crystal.

You would steep the same amount of crystal. If you want to get technical, I don't really see obtaining a 75% efficiency with steeping. If it's a concern, bump the amount up by 10-15%. Is that what you're referring to?
