Sorry to resurrrect this thread, but regarding Campari and Negroni, was there ever a consensus as to whether the Negroni is premixed, or is it freshly made in GF?

My reason for asking is that my father is a Campari and soda man, very Luton Airport I know. I'm sure he'd enjoy one as I accompany him to YVR later next month. I did manage to find Campari in the Cathay F lounge when BA YVR flights have been via T3.

I haven't seen any evidence yet that Campari itself is available in GF. I'm grateful in advance for any information on this.
