I've always tried the minimalist approach and only used sulfites at bottling time and not with my rackings. Just checked in my wine bunker and it looks as though I may be getting a bit of funk starting to grow in a few carboys. I was going to hold off on racking after some of your suggestions on here and I'm not sure what to do. For some reason my Cab dropped plenty more lees but my pinot, merlot, and sangiovese have not. I was wondering if I racked one more time and wanted to add campdens should I use one per gallon? Also the last racking was on October 24th. After talking to you on here I was thinking now is too soon but due to the film on top of the wine should i rack and add campden or just add campden to the carboys as is to avoid more racking and possible oxidation. A quick response would be greatly appreciated as I have today and tommorrow off of work and it will be my only time to take action. Thanks in advance, Ken
