Ok, I'm trying to figure out what the gravity and IBU's are on this recipe and have used beercalculus, tastybrew, and brewpal (iphone) to try and estimate what my results should be. All three came up with wildly different results and I don't understand why.
Recipe - Rye Pale Partial Mash
-- 3 lbs Rahr 2-row
-- 1.5 lbs Weyermann Rye Malt
-- 0.5 lbs Carared
-- 6 lbs Amber malt syrup late addition (15 min)
-- 1 oz Summit 18AA (60 min) pellet
-- 1 oz Palisade 7.5AA (15 min) pellet
-- 0.5 oz Palisade 7.5AA (5 min) pellet
-- 0.5 oz Palisade 7.5AA (dry hop) pellet
Results:
Beercalculus.com:
OG: 1071
IBU: 46.8 ??
ABV: 6.9%
Tastybrew.com
OG: 1069
IBU: 97 ???
ABV: 6.7%
Brewpal
OG: 1067
IBU: 66 ??
ABV: 6.8%
Ok, I can live with the gravity being pretty close, but what is going on with the IBU's? I tripled checked to make sure I put in the numbers the same on each one but the results always came out this differently. What gives?
Cheers
