I have two white wine kits that had dropped perfectly clear until I added more K-Meta and tartaric acid. It looks clear until I put a flashlight on it and then it looks like fine dust particles floating. One has been this way for 6 months. Should in try other fining agents or cold crash? I...

I see charts and calculators that tell you the desired free sulfite in wine based on the pH. Is this the level of free sulfite I want at bottling or do I want to account for the loss of free sulfite during the bottling process? Thanks in advance.

I just purchased an 80g pack of GRE yeast. I will be using it on 2 different batches now. How long will the remainder of the yeast be good if I vacuum seal it?

I have the opportunity to purchase a 2015 Winexpert Pinot Grigio Verduzzo kit highly discounted from last year. Production date is January 11 2016. Is this kit too old or would it be ok if I replaced the metabisulfite? Thanks Dan
