Water, water, everywhere...

So now that Noble Square Brewing is in a new location, we have to take in consideration our new environment. And for brewing beer, that means water. Señor Brew™ checked out the California Water Service Company's website to see what the water chemistry in Redondo Beach looked like.

The report on the site says our water is a mix of groundwater and purchased surface water, and gives different readings for each. Unfortunately, it doesn't say what the mix is, and doesn't say if it changes throughout the year. Luckily, the Noble Square Brewery is now located right next door to a well, and the storage tanks for the well (pictured in the title photo for this post). The water guys stop by next door regularly, and Señor Brew™ was able to confirm that my water is always 100% groundwater, except for the rare occasions that the well is shut down.

Unfortunately, there are a number of "not applicables" listed for important chemical components of the groundwater, such as calcium. Señor Brew™ has been playing phone tag with a water quality specialist for CWS, and has yet to determine what the chemical composition of our water is. Once we find out, we'll post it here, so other brewers in Redondo/Hermosa Beach that are on groundwater don't have to jump through hoops to find out, like Señor Brew™ has.

One thing we are able to determine from the site is that we are super high in chlorides, with an average count of just under 350 parts per million. It looks like we're going to have to purchase water that is free of chlorides, and dilute the tap water to get that count down. It also looks like we're going to have to treat the water to get rid of the chloramine used to sanitize it.
