My APA

[cigarmitch]

So I am trying to brew up an APA. But want to make sure I am calculating OG and FG right. My process:

2.5 Gallons of boil, final batch size 5 gallons


60 min-
3.5# Golden LME
2 oz Galena

30 Min-
1 oz Cascade

15min-
6# Golden LME

Flame Out
2 oz Cascade


I used The Beer Recipator website to figure this stuff out, I THINK... Here are the stats I got from it's calculations.


The finished volume is: 5 gallons Low High
The original gravity is: 1.101 1.044 1.056
The alcohol is: - 4.5% 5.5% v/v
The color is: 11 HCU (~8 SRM) 4 11 SRM
The bitterness is: 43 IBU 20 40 IBU]


It didn't have a place to add to the fact that I am split boiling the LME. Does that effect anything?

Do you mean your late LME addition? That has an enormous effect on the IBU's. I've run a few experiments on hopville.com concerning late malt additions and I've increased my IBU by as much as 30 on certain recipes while using the same amount of hops. If you mean you are actually splitting the boil into 2 pots I can't say anything about that.

I might be missing something but when I run these numbers through hopville I am getting a much different output. I see an average OG of 1.065, IBUs at 117!!! with the late malt addition and SRM at 7. This assumes you are talking about late LME addition.

 

[cigarmitch]

Yeah, I meant late addition of the 6# of LME. My bad!

When the batch finished it came in at OG: 1.072 so I guess the initial numbers were off a bit.

Using hopville, I got an IBU of 137.7. Sounds like I will have all sorts of hop flavors!

20 minutes after pitching the yeast, I have a bubbling airlock, no turning back now!

As I understand it, boiling your hops in a lower gravity wort will extract more hop flavor/bitterness out of the hops.

If you only boil part of your malt extract and add the full amount of bittering hops at the beginning of the boil, you are effectively getting a LOT more bitterness out of those hops.

As I understand it, you should reduce some of the bittering hops when boiling with a late malt extract addition.
