Stabilizing wine before back sweetening

[browndd1]

My question is that I cant remember whether I added the campden tablets and potassium sorbate to my 5 gallon carboy of wine over a year ago. Should I add them since I cant remember? What if I did in fact add them and give it another dose will it be safe to drink and turnout ok?

Thanks,
Dave

Definitely add the k-meta. If you are going to back sweeten and bottle soon, then add the k-sorbate as well. If you did add the recommended 1/4t a year ago it’s probably all used up by now. Many add that dose every three months while bulk aging. If the wine was topped up and the airlock maintained I have stretched that to 6 months.

If you indeed forgot to add it a year ago the wine may have started to oxidize regardless of the airlock. Give it the smell test… if it smells ok give it a taste. Let us know how it turns out.
