Default How Many Use RO/DI

RO and RO/DI water get mentioned fairly frequently here. I'd like to know how many people actually use it in their brewing and how many who don't intend to.

If you use RO/DI water infrequently please tick first option which would better have been worded 'I do not use RO/DI water or only use it sometimes and do not intend to use it or use it more frequently in the future"

Thanks, A.J.

I use it, but honestly, without an actual water report, it may be a waste of time/money/effort.
I use it because I have a system already in-place for other hobbies, so why not. I know for a fact my house water has chlorine in it, and without a water report, I really didn't know where I was with minerals, so I thought it best to make my own.

OK you just blew my mind. Your stated goal is to divide everyone into two groups, people that do, and people that don’t want to. Oddly you’ve left out people that don’t, but want to.

The poll sorta fixes that, but constrains the ones that do, to the ones that do it a lot.

So why would Mr. Probability design a poll that fails to consider all the possibilities?

People like myself are excluded from the poll. I would use RO for a Pils or a Helles, but not for a Porter. Others I might use a mixture.

Seems like a lot of people you’re leaving out.

I use RO from a grocery store in all of my brews to cut the alkalinity of my city supply. We have plenty of calcium and magnesium in the remaining tap water.

I use ~ 85-90% RO for pilsners/Kolsch beers down to 25% RO for stouts. I also add 88% lactic acid to obtain the proper mash and sparge pH (usally around 2 mL).

Did you see option 3: "I do not use RO/DI water but intend to soon."

Because he put it together to fast and you can't edit it?

I've changed the OP to make it clear that people that don't use RO/DI very often should indicate that they are not RO/DI brewers.

Thanks for straightening that out, you had me worried.

What about the people that can’t spell RO?

You left out, as needed. Now that I have a water report (albeit a yearly average) I'll use as needed to get my water to where I want it for specific brews. I had been using the primer until my last two brews though.
