I used my Freak of Nature water profile the first time I made this, but I thought it came off as too bitter. Can You Brew It recommends:

"RO Water. Add gypsum and CaCl to 100ppm"

Which sounds very reproducible but... 100ppm of what?? Ca? SO4? what?? I can only imagine that the guy who transcribed the recipe had not idea about water chemistry so I may have to listen to the podcast myself to decipher this.

Notes

Started with the Can You Brew It recipe for Union Jack: http://www.homebrewtalk.com/showthread.php?t=188929

Supposedly, Double Jack is at least the same grain bill but with a higher gravity.

They also suggested Cara Stan as a substitute for Cara Malt.

The hop schedule is taken/adapted from: http://www.bertusbrewery.com/2012/11/ipa-clone-series-firestone-walker.html I actually made this recipe but found that I likely messed up by switching the yeast to US-04. It wasn't good, but the guy who provided that recipe was so thrilled with his result, I thought it was worth keeping.

My biggest complaint having made that beer was that the malt flavor wasn't right (not sweet enough) and that the aroma had a lot of yeast quality I wasn't expecting. Both can be corrected by just using WLP002. But I do like the idea of tweaking the malt bill a bit as well.
