Stability & Preservation

Estimate cold and heat stability moves and check molecular SO2 coverage against microbial risk.

Estimate chill targets from the -4C rule and size the KHT seed addition.

Using the -4C rule, chill the wine to about -4.0C and seed with 151 g KHT for roughly 7 days.

Cold hold	7 days
KHT seed	151 g

Warnings

Seeding tests and conductivity checks are still the better validation method than temperature heuristics alone.
