I went to brew the latest version of my house IPA yesterday and took another look at the Brun' Water because I wanted to see the difference (if any) between brewing with distilled and RO water. I have always used RO water, but wondered how much salt was getting past the RO system from my water softener, and softening the taste of my IPA.
ANYWAY, I was looking at Brun' Water and noticed that on the Water Adjustment page for the Desired Water Profile, I had selected Pale Ale. I wondered to myself if this was the appropriate profile so I switched it to Amber Bitter (my IPA is 8.1 SRM). Immediately the cells for Gypsum and Epsom salts turned red. My target was just under 300 ppm for Sulfate, and it was sitting at 298.6.
So my questions are:
For an American IPA with 136.7 calculated IBU's, what is the correct Desired Water Profile?
Given the fairly large change in profile, what beer style does Amber Bitter represent if not an IPA?
