Thank you everyone.
CO2 huh ...
I am located in Vancouver, Canada.
Temperatures in the winter usually get down around freezing for a couple
weeks
My wine sits outside - for convenience and for cold stabilization before
"bottling" in March.
2004 Lodi Merlot dropped out a lot of TA.
I will stir well before the final racking of my next wine (from frozen
Yakima Cab left over from 2004 harvest).
Malolactic had not occured to me.
I will get a kit and run the test.
Thanks again.
