Vp41 previously opened

[nicklausjames]

I opened one of these vp41 packages that is for 66 gallons and used abou half of it. This was 4 weeks ago. I took it out of the fridge 2 days ago. Is it ok to use with a white wine I am almost ready to malo? Or is it garbage?

One way to find out (though I think you're fine). Be sure to use Acti-ML and Opti-Malo.
