It was barely nine in the morning but already the temperature had to be nearly forty degrees. Behind Matt, twenty-one hectares of vineyard spread up the valley in neat green rows, standing out against the red South Australian earth. To his left the white grapes showed faintly gold in the bleaching sunshine. To his right, black grapes made purple speckles among the green vines. This summer had been one of the hottest and driest on record. Now it was finally February, the beginning of autumn, and the grapes at Forrest Vale vineyard were ready to harvest. The harvest was always a special occasion for Matt and Jenny. Friends, neighbours, family and extended family came from miles around to help. For the next two weeks the couple’s wooden ranch-style house, which nestled at the bottom of the valley, would be full of guests. Matt took off his bush hat and wiped the sweat out of his eyes, then stepped up onto the wooden decking that ran along the back of the house. Jenny was down at the local store getting supplies for the buffet lunch that would welcome the workers.
