Well, today's the one month mark.
Testing day.
I'm guessing based on my last few brews it probably went dry at around 11%, maybe a bit more given the bit of extra sugars from the syrup.
Still have a jar each of honey and syrup for step feed/back sweetening, but maybe I'll keep this recipe dry- last time I kept it dry and it came out pretty good, and my other recipe came out really sweet so...
