Also, I am curious. Why is this beer so bitter? The hops in it are low as and there aren't a lot of them
1.) It has a BU:GU close to an IPA (0.68)
2.) It uses darker malts (I think they've modified the recipe to use pale chocolate instead of chocolate)
3.) The recommended yeasts have a tart finish to them
4.) The burning/caramelizing of the wort sugars during the boil adds to the bitter effect (may or may not be applicable to your case)
5.) The hardness of the water you use can vary the bitterness/perceived bitterness
There's probably more but that's all I can think of right now.
