The CO2 released early in the fermentation acts as a preservative (creates a non oxidizing environment) Once active CO2 release has stopped/slowed the preservative effect goes away.So I guess I will add the k-meta now with the initial sit?
We find that It is convenient to have meta (which chemically maintains a non oxidizing environment) in place once you transfer to the secondary fermenter with air lock and not watch every day or wonder if CO2 is done.
