Ok. Ok. Took extra care to fill my test bottle to exactly 25ml. Let stand (capped) for 1 hour to get to room temp. Added 2 drops of titrant before test. Added the 5 drops of blue which took about 30 seconds to totally mix. Started adding my drops very carefully to be exact. At drop 41 (counting the first 2) it turned slightly purple. drop 42 turned a distinctive blue. Drop 43 & 44 produced no change. So voila...CH=420ish. I guess the 41 degree water made the difference. Or maybe it was the wine! Lesson learned. DONT TEST 41 DEGREE WATER! Thanks Richard. Thanks Carl. I appreciate the concern and especially the guidance.
