Yep I messed up and criss crossed the needed pot meta, it should have read:
Tart red cherry, ph = 3.30 titret read 27ppm and Fermsoft sulphite
calculator says to add .26 grams pot meta to hit 35 ppm.
Tart black cherry, ph= 3.28 titret read 21 ppm same sulphite calculator says
to add . 46 grams pot meta to hit 35 ppm.
Ok i'll leave about 1/2" headspace when corking and I"m one of those people
that can taste sulfites in smaller amounts so I'll shoot for 30ppm instead
of 35.
Thanks,
Rick
