We are running into some water usage limitations with our well. We are considering rainwater catchment tanks. Anyone know of any medium size (7 - 20 bbl) breweries using rain water catchment for brewing?

Brewing with rain water?

Rain water is foul. It is full of atmospheric pollutants that you'll need to scrub out. Not to mention bird crap and leaf litter from the rooftops. Used to know Jamie at Bermuda Triangle brewery who RO'd his rain water before use. Pain in the butt according to him. But according to a leading beer website, that brewery was closed in 2002. Still, I recall other folks using rainwater with lots of hardware & precautions. I'm sure you can do it, but it's not a free ride.
If you're tapping out your well, is it possible to run it into tanks during off-peak usage for later use? We have four 2,000 liter tanks we use as a buffer for our (unreliable) municipal service. Gets us by a day or two when they have no water for us. Good luck!Last edited by gitchegumee; 02-04-2009, 05:37 PM.Phillip Kelm--Palau Brewing Company Manager--

OK, maybe I was a bit harsh with the word "foul", but I wouldn't drink rainwater here, and we are a thousand miles of big, blue, Pacific Ocean from anywhere. I doesn't get much cleaner than that. First, you will have to be scrupulously clean with your catchment area. Bird crap and rat piss are known to carry potentially fatal fungi/bacteria. Strain out the big chunks before storage. Clean your cisterns regularly and dose sodium hypochlorite at 1-2 ppm to keep bacteria and algae at bay. Pump out and rough filter the brewery's incoming water, then charcoal filter out the hypochlorite, then fine filter out the charcoal dust. Routinely check your free chlorine in both the cistern and out of the filters. Of course, rain water will have no dissolved solids, so you'll have to add all the minerals you require. And rain water contains more dissolved gases than well water, so you may wish to boil it before use as brewing liquor.
Another option you may have is to use catchment for cleaning and washing, while using well water for brewing and sanitizing. That should cut your well water usage in half while still gaining maximum benefit from catchment. You wouldn't even need to carbon filter your water this way.
BTW, we had an unusual wind pattern two years ago this March that had our pristine air and crystal air visibility contaminated with this yellow dust from China. And we're thousands of miles away from the source. I'm all in favor of grabbing free anything, but rain water isn't the same as well water. All the same, breweries use water for many things and not all of them require perfect brewing liquor. Best of luck and I hope you can make this work!Last edited by gitchegumee; 02-06-2009, 07:30 PM.Phillip Kelm--Palau Brewing Company Manager--
