Wow, a few surprises on this post.
First is to mookiex4. You make better wine with honey than with fruit flies. Attitude change my friend. I need to correct your 1 Campdon tablet per gallon statement. That is for preventing oxidation and bacterial growth. The correct dosage for "sanitizing" is 3-4 table spoons per gallon (my k-meta bag says 2oz/gallon). That would be about 48 Campdon tabs per gallon.
Second is that there has been no mention to the fact that if you are not going to back-sweeten your wine, you don't need any sorbate at all. None. Nada. Zilch.
Someone earlier in this thread mentioned adding sorbate "while bottling". Assuming that they are sweetening also, I think this is a dangerous practice. I always wait at least one week after stabilizing (k-meta and sorbate), back-sweeten, wait one more week (to make sure you've not started another ferment) and THEN bottle. These are MINIMUM times.
Third is a question about oxidation. JohnT made a statement about one gallon for long term storage, but once starting to consume, it should be transferred to 750ml bottles to prevent oxidation. The reason being that it would not be all consumed in one sitting. This makes me think that oxidation happens a lot sooner that I previously thought. I sometimes have a bottle of open wine sitting on the counter for a week or two as I regularly use it in cooking. I also sample while cooking (just to make sure it's not gone bad
) and have not noticed any ill effects from this practice. I've also not been overly concerned about a little access head space while brewing kits. The exposure time is usually 2-3 weeks and didn't think oxidation happened that fast. Please educate me on how fast it happens.
