I know this is an old thread but I was thinking about kegging my next batch of wine. Is there any downside with regards to the beer line? Will the wine leech into the line and ruin it if I want to serve beer again on it later? Of course, I would clean and sanitize the line after the wine is gone. Push oxyclean solution into the line and let it sit, then rinse with warm water and sanitize with star san. Any worries about the line?
