Well, we did the honours over a 1992 Leeuwin Prelude Cab Sav we got about 1995 for $22 - a lot for a wine back then! The storage had been very poor, but the cork had stayed sealed and the wine was in reasonable condition. It was rich with a lot of flavour, but it would have been vinigar soon I think - it wasn't a perfect bottle by any means.
There's an annual concert at the winery in Margaret River that's worth going to - Sting played this year.
