Actually the wine is a white Chardonnay if that makes a short term difference, I should have mentioned that in the first post sorry.
Thanks for the responses. I don't believe there was any airlock activity, but it seemed to stay at the top.
I did end up topping it up to 1" below the airlock bung, it took nearly the whole bottle but I guess better safe than sorry.
I think from now on I'll just always top it up, it's not like it takes long.
