Do pH buffer have a short life. I opened new packes of 7.01 and 4.01 buffer in mid august from packets I had purchase a year ago. They produced and error of 0.64 when I used them to calibrate my meter.
I did not discover this for a couple of weeks, when the pH and TA numbers on my grapes did not make sense during ripeness testing.
Did one of the buffers go bad or was it just bad to begin with? Any thoughts?
