I know this sounds like a crazy question, but I was brewing with a couple friends at their microbrewery. They have a 7bbl system and started the water the evening before, and it boiled much longer than planned. 40 of the original 350 gallons (about 11.5%) boiled off. They topped off with more water and proceeded with the brew day. But while brewing we were talking about this and were curious if there would be any issues with this happening. I believe the water maybe a little on the harder side, but don't remember the exact water report.
