I am doing a RJS South African Sauvignon Blanc kit (no skins). I started Primary fermentation with Bentonite, juice from kit, and rehydrated yeast from kit. SG 1.093. Instructions call for a move to Secondary after 6-8 days. I had to leave town on an emergency, so rack to Secondary happened after 17 days (YIKES!). Added oak chips to carboy during rack to Secondary. SG 0.99. Instructions call for 14 days in Secondary … then Stabilizing & Clearing (Sulphite, Posassium Sorbate, Kieselsol, Chitosan). But, I want to let the wine sit on the oak for an extended time – maybe 2 months; stirring occasionally to ensure greatest contact with the oak. My concern is that fermentation was completed during the extended time in Primary, so I likely have no CO2 cap sitting on top of the wine to protect it from oxygen (about a 3” diameter exposure in the neck of the carboy). Should I be concerned about oxygen exposure? Can I let it sit for the desired 2 months before Stabilization without concern for oxidation? Thanks for any insights! Mark
