There was a difference in the sediment colors - the heavier sediment
was more purple, the lesser was more grey. Both were mostly sediment,
and what tartrates there were were mixed into the muck by the time I
was really looking (they weren't big honking crystals, they were more
fine. I did notice some). Different yeasts, though I pressed both
very late (near 0Brix).

The "predictable as a hurricane" comment is well taken, Joe!
