I didn't have any specific questions. I just wanted to post in an advanced discussion thread so I could be cool. I'm thinking my awesome plan backfired.
Thanks for the link for the spreadsheet. Unfortunately, the computer with Office on it just crashed, so it will be later before I can mess with it. I've found a couple online that I've playing around with.
I've been using Spring Water, but at 82 cents a gallon, it adds up. As cheap as I am, I figured I'd try to use my tap water to save some coin. Every beer I've made with the local water has been terrible. Except the last test batch that I used Campden tablets in. There's still a slight "sweet acidic????" taste to that batch, but not the terrible off flavors that were in the original batches. I'm not sure if that flavor is a result of the water or the fact that I just threw together a crappy recipe with leftover grains.
I'm usually not real precise when I brew. In a similar manner that cooks just throw stuff together. I don't exactly measure the amounts of Gypsum I put in the water. I just throw some in. BUT, I'm really going to get "scientific" about this in hopes that I can use this water with decent results.
