Hello, novice kit brewer, seeks advice

[Wino Cat]

Hello, I'm a relatively new kit brewer: so far I've done a few Wineworks, Solomon Grundy and Australian Blend 30 bottle kits, all pretty successfully. However, my latest is a Vintners Reserve Sauvignon Blanc. It tasted great before stabilising and fining, but yesterday when I bottled it, it tasted pretty vile. I may have left it on the sediment too long in the bucket before racking, and a degassing volcano left a bit more headspace in the carboy during fining: does it sound like this batch may be ruined or will a few months in the bottle make a big difference?
Thanks for any advice

If you plan to bottle soon I wouldn't worry about too much headspace.
