Hey Geoff,Welcome to the forum. I interested to see how you go. I'm also based in Melbourne (well.. Korumburra) and had a 100kg of Shiraz from Heathcote on order but had to cancel because delivery ended up clashing with a booked holiday. I still have my own Pinot noir & Chardonnay grapes so not at a loose end.
Good luck
We are pressing today! Just finished work and waiting on friends coming over. Hopefully the Melbourne weather doesn't rain haha.
