The Iron Liver Distiller

Hello all, I am looking for the best yeast nutrient for a good bourbon. Does anyone know about BSG's Superfood Nutrient? And if so, would you recommend it for this purpose?

Hello all, I have recently joined a new distillery after having distilled at two prior distilleries. We are mainly a bourbon distillery, which I am familiar with; however the largest difference here is that our mashing process will be done in a Mash Vessel as opposed to a Lauter Tun, which I am much more used to. Does anyone know if there are any major differences in the process? I know I will have to now "ferment on the grain," but does that entail much difference in the chemistry of the process? I typically have used BSG's "superfood yeast nutrient" as the nutrient for fermenting, however this has always been off the grain. Will this still work? Any advice or pointers about the differences are welcome, please and thank you!
