Some other hobbyists - like aquarium owners, especially those with reef aquariums - need to measure higher pH, about 8 - so they either use three points calibration, or two points, but with the use of pH 7.00 and pH 10.00 buffers. Your 6.85 buffer stands for 7.00 :) If you want to know more about pH meters, their usage, calibration, theory behind, history and so on, and so on, and so on - visit my site, http://www.ph-meter.info In the case of wine you don’t expect high pH, as all wines are at least slightly acidic, so two points calibration is enough.
