Personally I'm going to start testing water.JQ
JQ, this is an interesting topic.
Water is one of the more important and more neglected factors in homebrewing.
I have a water analysis from the city (when I get the bill) but I'd like to hear how you're going to go about testing. ex: are you going to build your water, add calcium carbonate, etc.?
I guess it'll probably depend on the style you're brewing...
Anyway, it would be good to hear about it.
-
Yeah I was thinking about this... going to start with some pH strips but even that doesn't go far enough. Really, I need to test the buffering capacity of the water.
JQ isn't using municipal water, so it's particularly important for him.
-
So for equipment / consumables for this - does anyone have a shopping list for testing water pH / buffering capacity? To my knowledge both are important.
-
Assuming the well is consistent, I have the test that is required by the Province whenever a well is re-drilled that tells me the exact amounts of all sorts of things in the water.
Still researching a bit, and I've brewed with both conditioned and raw unfiltered, unconditioned water to see if there is a blatant difference, but haven't come to any conclusion yet.
Watched the first of a series of videos online, going to watch the rest soon.
Thing is, when the beer is already good>very good, it's tough to be too worried about efficiency, when really it's another buck in grain to balance off against efficiency issues.

To be honest I'm not incredibly concerned about efficiency. I have a good idea of what my system is for now.
If making adjustments to the water is a factor in making a better beer, I'm interested in understanding.

5.2 Stabalizer works for me :P

Since we have a water treatment plant that provides water to the town as well as the base, water quality is something directly related to my work. I have no clue as to how certain parameters apply to brewing but I do know what is tested, how it is tested, and why
some interesting reading here, if you're interested

and Richard - what you're looking to test is PH and KH ...the cheapest place for you to get a test kit for those is a pet store (aquarium test kits). Don't use the PH test strips, they're pretty much useless. I have a PH test kit for my tank but I don't test KH, a competent pet store can test a water sample for both those ...the place next door to Giant Tiger is good and there's a guy there who knows what he's doing

I actually have the city water report as a PDF/URL if anyone's interested.
http://www.fredericton.ca/en/environmen ... ts2010.pdf (http://www.fredericton.ca/en/environment/resources/TypicalResults2010.pdf)
These are the "typical results" for people on city water for 2010.
I know it's 2012... but this is a pretty good baseline anyway.
-
Yes indeed - I have a PH tester as well, and the Fredericton PH listing in the doc Happy referred to is pretty much exactly what I get with my tester (a hannah). The Fredericton test info is also in the water profile on the Brewblogger site.

Thanks guys; I'll check it out.
