A few post ago we put up a post about how the hardness of water effects your brewing efforts. Well I wanted to find a, “dummy” map to help you out what your water might be like if you live in the USA and you didn’t want to send your water out.
I found this map online and thought it was a pretty good reference.
All in all, it is a pretty good map as a quick reference to judge where you might stand on the harness of you water. This will help you out when you are considering to make lagers or ales.
Hope it helps,
