How much campden/k-sorbate to stabilize a 100% finished ferment?

[Horseflesh]

I have a 9 month old carboy of painfully dry apfelwein. It's my intent to keg it, stabilize it, and sweeten with FAJC.

Since I am not trying to stop an active fermentation, how much k-meta/k-sorbate do I need to use?

I see 1/2 tsp/gal k-sorbate is commonly referred to, but for campden/k-meta I see values all over the place.

1/2 tsp per gallon of k-sorbate, 1 campden tab per gallon or 1/4 tsp k-meta for 5-6 gallons.

1/4 tsp total, not per gallon right?

Thanks!

Sounds about right! If you had not sulfited previous to this what aprox would be your ppm at 1/4 tsp? 50ppm?

 

[Maylar]

Yes.
