Hmm? Maybe you should move UP to Bru'n Water?
Martin, since I started brewing last Fall, I have valued your inputs on this forum as well as HomeBrewTalk. Thank you for all you do for us pikers. I have read your website (https://sites.google.com/site/brunwater/water-knowledge) multiple times... Yeah pretty sure I still couldn't pass a test based on the material, but I keep trying.
So having said that, I have a copy of Bru'n Water on my computer which I open periodically. It is just too complex and intimidating for me at this stage of my understanding. The reason I use EZ Water is because it is easy.
Someone in my past said "Quadratic equations are easy if you know how to do them." I am sure the complexity and detail are there for a reason and I'm equally sure it doesn't seem like it should be intimidating in the least to you (or maybe even that it should be self-evident). But looking at your Bru'n water spreadsheet kind of reminds me of a political cartoon I saw once: The then current president was sitting in the pilot's seat of a jumbo jet looking at the array of dials, controls, etc., and was saying, "No Sweat. Just show me where on is."
BTW I voted for you for the AHA Governing Committee. Thanks for all you do.
1. I flunked chemistry classes
2. I get confused easily (I even had to label salt jars with +pH or -pH )
3. I used Brewater and EZ Water for a long time with mixed results
4. Martin's spreadsheet has more stuff, but in the long run, is more accurate and has some built in double checks that tell you when things are wrong. (ie: the beer color - if it and your recipe don't match, you've entered your grains wrong)
5. It can be used whether you really understand water chemistry or not - using it will actually teach you and give you a pretty good understanding of what these ions are actually contributing as you tweak your beers.
I encourage you to start playing with it. It's most useful for those of us who don't know it all, and Martin seems always ready to answer your questions and help where necessary. Don't be afraid of it.
