In October I purchased 12 gallons of chardonnay juice direct from
California. It was shipped 30° F

I fermented this to 1.010 then racked to secondaries.
I added SO2 and french oak
Took an acid reading, it needed no adjustment.

Since the end of October it has been sittinging in these secondaries.
(2 5 gallon sealed corny kegs)
Every other day I was bleading the CO2 from them.
These are stored in the cool garage.

Since December when the temp dropped, there has been no more CO2
bleed-off.

I looked at it today.
It is clear and has a good taste.
I took an SO2, it was 17ppm

My questions...

I was thinking of fining, sulfite and racking the wine. In
preparation for bottling in the spring.

This would also include trying to get all the Co2 out of solution.

What should I use for finning?
I have bentonite, sparkaloid and polycar. Any prefference for a dry
chardonnay?

I will be racking these back into corny kegs, any suggestions to free
up the Co2?

Should I place them back in the cold garage?

Should I adjust the SO2?

Anything else I should do??

thanks
