I was brainstorming and came up with a possible way to make sure that the wine doesn't oxidize over time in the bottle. One could soak a paper towel (or coffee filter or something) in 99% rubbing alcohol, place the soaked paper over the end of the straw, and blow clean (hopefully) CO2 into the bottle before racking the wine. What do you guys/gals think of this idea. It may not entirely sanitize your breath, but the high alcohol content of wine should keep it from getting infected.
