This is the 2nd Beer in my NHC 2018 run of beers. I’m brewing 5 in total and I got 4 entries so I’ll have to down select one. This is beer is based off the Devil’s Backbone recipe from a AHA presentation I found online a few years ago. It has done well but it has never made it to the finals at NHC. I’ve been tweaking it a little bit here and there and from the last time I brewed it I decided to up the bitterness just a hair (5 IBUs) and drop the Calcium Chloride to get it in line with the Gypsum but keep the Calcium at 100ppm. I also did a nice big repitch (0.5L of slurry) from a Helles I brewed just for that purpose. it appeared to have worked since it took 1st in the first round of NHC in tampa and 1st at the Olde Hickory Pro Am and scored in the 40s at both.
