Store Bought RO Water with Minerals Added for Taste?

[slayer021175666]

Went to the dollar store and they were out of my usual distilled water. I bought some Silver Falls brand Purified drinking water that was there, instead. Got it home and it says its RO water with minerals added for taste. My purpose is for yeast storage in the fridge. I drank some and it tastes right. Any reason I shouldn't use it in my yeast jars?
Thanks

It should be fine. The store brands usually add only a little mineral for taste (usually in the tens of ppm), and that shouldn't affect your yeast.

I figured as much. Thought I'd run it past the forum and see what folks had to say about it, though. Thank You, MaxStout!

The best yeast storage water includes a modest dose of magnesium. I can’t recall the dose, but it should be mentioned in an article on the Bru’n Water website.

If you like the taste of the water then there's no issue brewing with it. The two beers I made before buying water salts and such tasted good, and that's with Cincinnati water which isn't horrible but is generally hard. It's only an issue when you want to try and perfect your beer.

Just buy a cheap TDS meter (amazon, etc.). Then you can test it fast and get a pretty good idea what is in it. I buy cheap 4 gal jugs of RO water and it tests at a very low mineral content on my TDS meter which allows me to use it as virtually distilled water and add Mg or whatever is needed for your purpose.
