Hey brand new here on SE, but have been brewing all grain for about 5 batches now, mostly pale and amber ales. Going to brew my first Porter tonight, following Biermuncher's Black Pearl Porter recipe.
I've always used crystal geyser bottled water, but (considering it's a dark beer) should I add calcium chloride chalk? If so, how much for 5 gallons and when do I add it?
Where can I find a water report for Crystal Geyser bottled water?
EDIT: Fixed a mis-wording. Added bold text.
