My cider is infected

This is store-bought juice from Aldi's mixed with 2 lbs of Dextrose and fermented with cote des blancs one year ago. I've been letting it sit around and age, but I took a few taste-tests from it a few weeks ago and I think I may have been a bit too careless with sanitation when I sucked up the apfelwein with a turkey baster.

Is it redeemable? Or should I toss it? I've already added some K-meta but I'm not sure if that'll help or not.
