Yeah, I see that in my wine as well, that sounds like the polyethylene
glycol mentioned above. The tiny amount of benzoate mentioned worries
me mildly, if I added campden at each racking(I don't), would I build
up enough to inhibit yeast? If I added to little, would bacteria grow
and make the geranium smell?

This is all probably not worth worrying about. 'Tho I think I'll
switch to 5 gal amounts, and get a small gram scale for measuring out
metabisulfate, anyway.
