I've canibalized my RO/DI filter from my Reef Keeping days and now I am carbon filtering. If I ever need to dilute or start from scratch I can make RO/DI water, but that is just a pain in the ass. I've also started adding things like Gypsum and CaCl. I bought a pH meter but it was busted. New one is coming today (Thanks B3!)
BeerSmith and Promash both have good utilities for modifying water and approximating the water from famous areas around the globe....BUT, on the last Water Show Doc and Dr. Evil both stated that the major breweries aren't using tap water. Guiness is not made from Dublin Tap. The water in Antwerp is NOT what is in that Dubbel or that Wit (especially now, thanks Inbev
I've read Plamer and Miller, Daniels and Mosher, and of course Papazian, but there is nothing really of substance on water. Palmer tells you what does what and how much Sulfate will give you the shits. He even has a Nomograph (some chart thingy) that you can print out and connect the dots to see what to add based on the amount of dark malts in your beer. It's like Magic, but I don't get it.
I want to know what to add and how much to make a better Wit or a Pils or a Dunkel. It's nice to knwo I can emulate the crap coming out of the tap in Boznia, but they're not brewing with it.
Any thoughts, pointers, books I should read??
ahhhh... that's better
