I use Star San to sanitize everything, bottles included, when making beer. I read about wine folks using crushed Campden tabs/k-meta for the same purpose for wine. Is there a reason I should use one or the other for wine? Does it matter?
I prefer and use pot meta for everything, simply from a cost savings standpoint. A pound of the stuff will make years worth of sanatizing batches, and keeps well in solution. I still use campden for adding to musts or stabilizing wine (can't over/under measure crushing one tab per gal) but pot meta for all equipment/bottles.
