You know, I hear this all the time but I make my coffee with RO water every day and every single person who has it complements me on it and tells me it is better than any other home made coffee. As a bonus you don't ever have to descale or clean your coffee pot.

I also have used RO water since my very first beer (I have a lot of iron in my water) and my beer is great according to me and everyone who tries it. I do, as stated before, add some minerals to my brewing water, but it's nothing complicated.

We're not trying to personally attack you (or any 100% RO/DI user), so, sorry if it comes off that way. We're just stating the science behind it and how it relates to healty yeast. If it works out for you, i'll be the first to tell you keep doing what you do. As long as you like the results, that's the important thing.

It was never taken as and attack, I just wanted to be clear that great beer can be made with RO water. The science can be worked around, minerals that are made to be added to brewing water are easily had at all brewing shops. So as long as you have a sound understanding of the science behind it, you can actually have more control over your water by using RO water and starting from scratch.

Sure sure. I think some (at least me) were under the impression just RO/DI was being used, and nothing else (minerals) was added. That's all.

Honestly, I'ven never actually experimented to see the results. I just listen to Alton Brown.

Ok, so RO water is stripped competely. so if i add 1 gallon of tap to 6 gal of RO then i can divide all of hte minerals in the tap water by 7. correct?

Definitely take what I say with a grain of salt because I'm a relatively new homebrewer. But I was told in a beginners class at my LHBS that you shouldn't use straight tap water because the chlorine creates an unhealthy environment for the yeast. You can use a simple carbon filter it will strip the chlorine though.

Has anyone else heard this? I've been buying bottled water to brew with and even though it's not that expensive, I'll stop wasting my money if it's unnecessary.

yes it will but you need to run the water slowly through the filter. I'm not sure how slow. I usually take about 1 hour to fill 12-14 gallons. Carbon doesn't actually filter the chlorine, it absorbs it.. If you run the water too fast there is not enough contact time between the water and carbon.
