Well, if that's the case, that means the air that we breathe is loaded with contaminants. Maybe we should all quit breathing?

Just make a one or two gallon batch, no harm no foul.

Yep, and your breathing system has some elaborate ways to catching and removing those contaminants. How will you remove them from the rain water?

I'd say go for it. The level of contamination is so low as not make a difference. To all the nay-sayers I hope your kids never swim, you too, if you are concerned about contaminates think of what is in the body of water you use (pond, ocean, lake, swimming pool).

I do a pretty good job of not drinking the water I swim in.

I might be a naysayer but I also have rain-barrels..and alot of nasty stuff ends up in those barrels...

I would suggest OP put some significant thought on how he'll get a "clean catch" of a significant amount of rain water. To get 7-10 gallons of water from a single rain, he'll have to have a fairly large catch basin. Funny thing about catch basins: They tend to catch stuff from the air when they aren't catching rain. You don't realize how much stuff is in the air until you wash off a large surface like a roof...

The only -- ONLY -- way I'd ever do this would be to catch the water in a dedicated catch, I.e. no asphalt shingles or rain gutters, and then to RO the water. That's a minimum, and I'm not even 100% sure that's safe. But to suggest anything less stringent than this would be willfully ignorant of health issues. You'd have to do some serious research first. I've seen my rain gutters many times, and that some NASTY stuff in there. Look in anyone's rain barrel too; blech.

I think rainwater is on the acidic side (I've read around 5.5-6 pH) and it doesn't really have any ions in it because it is basically naturally distilled water. I would treat it like distilled water and add brewing salts (probably CaCl2 and gypsum) and maybe something to raise the pH if it's really low. I would probably filter it somehow too. I bet one of those ceramic filters you can take camping would work just fine. Or maybe even just a brita filter.

It's been raining here for like 2 weeks straight as well. I'm sick of it. This sounds like a good way to make the most of it though. Good luck!

And common sense says you shouldn't.

The mash and the boil will kill and sanitize everything. This is the basis of pastuerization. My only concern would be taste and sediment, which is why I would try to filter it somehow.
