OK, so I have a Reverse Osmosis unit at home, could I use this water for beer making? I know the RO removes a lot of minerals so I imagine I would use the gipsum. What do ya'll think?
 
You should also use yeast food, even if you are doing AG. Realistically, unless your water tastes bad, you are better off using it as-is.

Dude, my water is straight up NASTY! That's why I bought the RO in the first place... the funny thing is that my wife works for the local water utility... Ha!!
 
Ok, another reason I asked is that I was told that for lagers soft water was good.... I'm planning on doing my first lagger sometime soon, maybe in a month or so. Here's my recipe, let me know if there's anything that doesn't seem right... laters!

Shouldn't your water have some taste to it? If you filter the heck out of it, aren't you eliminating one of the characteristics of the beer. Not that I drink much of it, but isn't the "water" one of the selling points of Coors? Instead of using an RO water, wouldn't you be better off buying 79 cent/gal of bottled spring water? Just my thought.

No, truly good water should have NO taste, thats the selling point of Coors. (There's a Coors joke in there somewhere...)

...what's the chemical composition of the "spring water" you buy? I used to buy it too until 20/20 said most spring water is actually tap water from another area.

Every year we get a print out of our town's water composition. I only had to add gypsum to harden my water. Other than that most GOOD tap water chemicals are within a good range for brewing.:D
 
If your Tap Water is really nasty then RO (as you already the unit) maybe your cheapest option.
You can at least then 'add' properties back to your water to suit brewing styles as you say.
 
Interesting, I lived in Sunnyvale for ten years and the water there was great. Las Vegas, now, some days you could drink the water and some days you could use it to strip paint. I had an RO unit there, but wasn't brewing.

Pilseners need very soft water, so you're on track for them.

A good discussion of water hardness with numbers.

I lived in SF for 8 years and the water was great. I got a water report, and even asked brewers at anchor about the water and they dont treat it, so neither did i.
I think if your going to brew super clean pilsners then h20 filtering/treatment is probably the way to go. But for ales i wouldnt bother.

Yeah, SF gets Hetch-Hetchy water, which is consider some of the best tasting in the state, but I live in Union City and we get blended water, mostly ground water..which is really hard and not too tasty.... :-(
