I use my local municpal tap water and although it has changed a bit over the last 25 years since I’ve been living here and brewing with it, it still makes very good beer for me. Some investigation revealed that most of our local water comes from the Delaware-Raritan Canal near New Brunswick (NJ). It is heavily treated (coming from the canal, it would certainly have to be) but simple carbon filtration of what comes from the tap results in a very palatable drinking water and I’m happy with the beer it makes. This judgement is based on the flavor of the finished brew, rather than any technical angle.
I did finally have my water tested (post filtration) last year, and here are the results, attached below. Not being a chemist (and have never played one on TV. LOL) I’m only just now starting to wrap my head around what all the numbers really mean, and if anyone would like to weigh in with an opinion or comments on the water I use, I’d certainly welcome any input. Which famous brewing city do you think my water profile comes closest to? Just curious.
