They were at NHC, and I chatted with them.
I think they have a product aimed at the new all grain Brewer. They don't take the tap water into their product, it is one packet for a given style. Grist make up is not considered. It is similar to when I put one tsp gypsum into everything, but they have a few more minerals in their packets.
It might help some. I have the gram scale, RO water, a pH meter, and targets from Brunwater, so it is not for me.
