Fort Point Clone - numbers look off.

[marjen]

So I am getting ready to brew a clone of Trilliums Fort Point Ale. I copied the recipe exactly as JC from Trillium wrote it in a magazine article. I made only one change, 6.6 lb of golden LME I subbed to 6 lb of light DME.

I entered the recipe into brewers friend and the ABV, IBU and IBU are not lining up to what the recipe should be. For example the ABV is only 5.8 but should be 6.6. Looking for help on what I have done wrong??

The Extract Fort Point Recipe listed by JC.
6.6 lb golden liquid malt extract
1 lb wheat dried malt extract
4 oz dextrine malt
4 oz British crystal 22°L
0.25 oz Columbus Hops @ 60 min
0.75 oz Columbus Hops @ 10 min
1 tsp irish moss @ 10 min
2oz Columbus at hop stand @ 180° for 30’
Wyeast British Ale 1098 Yeast @ 70°. Dry hop as krausen begins falling (day 3-4).
4oz Galaxy + 1 oz Columbus dry hop (after 4-5 days)

1 pound of DME converts to 1.25 pounds of LME. That's 25% more, not 10%.

But that would throw things off even more. The original recipe calls for 6.6 LME and I have 6 DME. Original recipe is 6.6 ABV, vs 5.8 on mine, 45 ABU vs 29 on mine and 1.13 FG vs 1.16 FG
