bulk aging with Kmeta

[edsey]

I'm bulk aging a kit. I have added clarifier and racked it. It has been aging in the carbouy for 2 months. How often should I add potassium metabisulphite and how much should I add.

Ideally you would measure free SO2, ph and adjust appropriately. I don't do that. For five or six gallons, I add 1/4 tsp every three or so months.

Wine is forgiving, , ,
I add metabisulphite when I am doing a task on the wine as racking. For me I try to do a wine with three rackings over about ten months. 1/4 t sounds correct however I will weigh 0.2 gm per gallon.
Translation of process, I am concerned about air exposure and want to minimize oxidation.
