Rainwater Beer Systems for Brewing and Producing Beer

First rainwater beer Rainwter collection system Rainwater treatment and sterilization system Rainwater beer connection

Overview:

The rainwater beer system developed between RainHarvest Systems and 5 Seasons Brewery turned out to be surprisingly successful as measured in several ways: The quality and crispness of the beer, the purity and softness of the water, the environmental responsibility and general excitement over rainwater beer has exceeded everyone's expectations. Several breweries, large and small from all over the country, have been working on their own rainwater beer systems as they learn more about the potential uses of locally captured rainwater for brewing beer and also for the water-intensive cleaning processes. So we've created this resource page for the followers who want to learn more about brewing beer with rainwater. In this section we'll provide all the information and resources you need to begin brewing your own beer from rainwater collected on-site. More analysis, articles, links and reviews will be provided as they become available.

The system, installed during August of 2009, employs 6 stages of filtration followed by dual-beam UV sterilization to remove various impurities and ensure safe, high-quality water. The filtered rainwater has a pH of 7.8, a hardness of 0.73 ppm, is colorless, odorless, has zero bacteria or other microbes and passes all EPA Standards with ease.

According to 5 Seasons Master Brewer, Crawford Moran, brewers prefer soft water without a lot of minerals for brewing high quality beer. Another beer aficionado who works as a food section columnist from an Atlanta newspaper says that the Golden Number Ale produced using rainwater was crisper and better tasting than previous batches he sampled made from tap water.

5 Seasons not only uses rainwater to brew all of their various beer but they also implement several other interesting and unique sustainable measures:

  • The brewery uses used vegetable oil from the kitchen to boil the ingredients during the beer making process
  • They use locally sourced organic vegetables and other ingredients on the menu items whenever possible
  • They provide their used barley and hops, used during the beer-making process, to a local farmer who uses it as fertilizer for the produce which he delivers to the restaurant
  • Their catering truck is a 1974 Mercedes Benz fire truck which has been converted to run entirely on used vegetable oils (not bio diesel) from the kitchen.
  • They've installed waterless urinals in the restrooms
  • They are working toward offering the filtered rainwater to restaurant patrons as an option to standard tap water.

The system differs from a typical potable water system in that the processed rainwater is not tied into the building's plumbing system. The processed rainwater is introduced to the brewery at a large tank where other ingredients are combined prior to the main brewing process.

System Components:

The installed system consists of the following components:

This water analysis report report provides element concentration data from a sample of the filtered rainwater taken on 8/31/2009, as compared to the established EPA Maximum Levels, in addition to pH and Hardness Levels.

Filtered Rainwater Meets EPA Standards
This is the "Total Coliform and Escherichia coli Report" from the University of Georgia Agricultural Services Lab, documenting that there is no Coliform or E. coli present in the sample of filtered rainwater taken on 8/31/2009. The Method used was 'APHA 9223 B' from the American Public Health Association, Standard Methods for Examination of Water and Wastewater 20th Edition. Filtered Water Microbiology Report
