My first go at a YAN test, a few bumps but this may get us started.

pH 3.4
TA 6.25
Brix 21.6 starting to ferment
YAN 148.96 (sounds precise but it actually is calculated from a 0.8 measure, so I would say comfortably that the YAN is over 140 and slightly less than 149.)

Please post your measurements, or email me, and I will decide tomorrow if I should redo the test.

OK folks, here are the YAN results from Ian, Dave, and Don. Other chemistry numbers also included.

Ian: Brix 21.6, pH 3.40, TA 6.3, YAN 149
Dave: Brix 21.9, pH 3.39, TA 6.1, YAN 140
Don: Brix 21.8, pH 3.44, TA 5.9, YAN 168
Mean: Brix 21.8, pH 3.41, TA 6.1, YAN 152

My Numbers on the clear juice after 4 days cold soak in the creek at 7 deg C:
Brix 20.7, pH 3.66, TA 4.575
I Calibrated my refractometer with 20 deg C distilled water and calibrated my pH meter with new 4.0, 7.0 buffering solutions and Sodium Hydroxide solution.

Not sure why my numbers are so different. I did re-calibrate and re-test with new solutions but my pH and TA were the same.
Any recommendations?

My Lodi Zin #s
Brix 28
Ph 3.7
TA 6.5
Yan 210
I am reducing Brix to 25
May add some acid to lower Ph
