New Jersey Brewing Water

NEW! Added water test results for Middlesex Water Company covering Carteret, Woodbridge, and surrounding areas.

water_20091021_1143798498This article is meant as a workspace for everything related to brewing water, membership/brewer water chemistry research and data. Many cities are served by the same water system. If water is tested once or twice a year in a given system, the test data should be made available to other members on the same system to save effort and money. If you find that your city is on a system that has already been tested and included in the table below, feel free to use the data. If the test is more than 6 months out of date, it would be great if you can have a sample of your water tested to keep this database up to date. Note, if you are not a member but live in NJ and would like to contribute to this database, send an email with your water system # and test data to webmaster _at_ whalesbrewclub _dot_ com.

Bobby Notes: Great water but could use a touch of gypsum in the mash for more Calcium. Sulfate:Chloride ratio is naturally on the malt forward or rounded flavor side. Would definitely add gypsum to the boil for APA/IPA for more hop expression.

NOTE: The red strikethroughs on SO4 is due to a misunderstanding in how Wardlabs denotes Sulfate. In Agriculture, it's typical to measure sulfate by its weight in SULFER (SO4-S). To convert to the sulfate ION, or SO4, multiply by THREE.

Water tests from the table above should represent all the water in the same water systems as tested.

The presentation I delivered at the October 2009 meeting can be found attached to this article as an Adobe PDF which most of you can read. If not, grab the free acrobat reader on It contains a few extra slides that I wasn't able to cover at the meeting. They are examples of how to use the utilities to craft/correct the water profile.

I'll also be attaching my favorite water profile calculation spreadsheet in blank form as well as several that have correction data pre-entered. The file name will indicate which kind of beer style it's geared towards.

Note however that the spreadsheets below are still "in development". I've been working with it's creator, a user named "TH" on so it may change a little over time. For best results, download the newest version from
