Need Help with Hop Weights and Schedule for 60 IBU
« on: May 28, 2011, 08:18:57 PM »
I am working on a recipe that is measured at 60 IBU.

My setup is all-grain, 5.25 gallons (final product) 15.5 gallon keggle and 10 gallon mash tun.

The target recipe is:
OG – 1.084
TG – 1.020
IBU - 60
ABV - 8.7%

2 Row – 68% (about 11.15 lbs.)
Munich – 22.5% (about 3.70 lbs.)
C15 – 9.5% (about 1.55 lbs.)
Boiling Hops – Perle
Finishing Hops – Sterling

What I need help with is the hop weights and timing schedule to get to 60 IBU.

Who can help get me to 60?

We need more info....what's the AA of the hops?  What are you looking for in terms of hop flavor and aroma?

Pearle AA is 8.0 and Sterling 6.1 (Brewmasters Warehouse).

The recipe posted below - does this look right? While it does get to 60 IBU, would you go with more Pearl at 60 and less at flameout?

It all depends on what you're trying to achieve.  Do you want more bitterness and less aroma?  If so, then do what you suggest.

Denny, I am not sure  ???

I am going for a Double Dead Guy clone; Rogue lists the IBU at 60.

IBU measures the bitterness right? Then the early additions @ 60 minute would contribute the most while late editions (5-0 minute) would contribute the least.

Yeah, by the time you're down to 0 min. you theoretically get no IBU.  You might in reality get 1 or 2 since it takes a bit to cool the wort.  I'd recommend you go with Fred's suggestion.
