Help with Evil Cousin scaling

Beer Recipes
1

Wondering if anyone can help me scale this recipe down to homebrewer size.

I emailed Jamil to get his Evil Cousin recipe and he gave it as he brews it:

[quote]For 37 bbl:
2300# GW pale ale malt
50# C15
100# dextrose

600 g hop extract 60 min
8.55 kg columbus 0 min
8.55 kg apollo 0 min
11.4 kg cascade 0 min

6.65 kg columbus DH#1
6.65 kg cascade DH#1
8.9 kg apollo DH#2
5 kg simcoe DH#2

OG 16.4 FG 1.4

Ferment around 69F with WLP001. Mash is 149F.

[quote]Thanks.
For the 0 min hops how long is that in the whirlpool?
[/quote]

[quote]It used to be 90 min now it is just 30 as we can knock out at a bbl per minute.

Here’s what I put into Beersmith. I realized the percentages are different, I was rounding… should I not do that? Also, I had no idea how to translate hop extract to regular bittering hop. This uses my best guess.

I think you would want to stay close to this percentage.

94% - GW pale ale malt
  2% - C15
  4% - dextrose

I have seen  (somewhere?) to use 20AAU of high-alpha bittering hops per 10 ml of extract.  You will need to get the weight to volume on grams to ml for the extract.

Okay for hop extract I see its a density of .9 to 1 gram per ml so it would be 540 to 600 ml in the full scale recipe. So you would need to scale that to your 6.5 gallons…
