That was my thought at the time. I ended doing a 2:1 Gypsum:CalCloride Which is opposite what one might encounter in a city like Munich. Oh well.
I did my first step mash. Since I BIAB I haven't had the opportunity but with the light grain load here I thought I would try. I did a rest at 113 and 140ish and stopped at 156 for my final mash temp. In the end I also did a 90min boil which I haven't done in years.
