I just got a pH meter and will be monitoring my next brew session. Where in Vancouver do we buy pH buffer solutions (pH 4 and 7) for calibrating the electrode?
FYI: I'm planning on adding 7 g CaSO4 and 3 g CaCl2 for an APA (pre-boil volume around 7.2 gal).
Yeah that is probably enough yeast energizer. Some people don't think its necessary for an all grain batch anyways. Apparently the recommended ion levels you see quoted in books is from lab tests with sugar dissolved in water, not beer. I asked dan once about calibrating solutions and he said you can get them at any of the pot stores
My meter came with the 4 and 7 and I got bored of testing before I ran out of solution. Post your results, I'd love to see them. ...and here is AJ's guide to using a pH meter http://www.homebrewtalk.com/f128/ph-meter-calibration-302256/
...really helpful as the instructions i got with the meter were useless
