This was from the assistant brewer way back in 2011. Also, fwiw, do not take what ingredients that are listed on the site as scripture. Abner has a ton of Citra in it and isn't listed as one of the ingredients on the site.
has there been any discussion about water treatments? i know in the mitch steele IPA book for the alchemist El Jefe recipe they point out targeting 400 ppm hardness and 50 ppm alkalinity, if memory serves.
