(Decanter) - While Western Australian winemakers have been sweltering in soaring heats, Margaret River winemaker Clive Otto from Fraser Gallop Estate has been working in freezing temperatures to create his own 'ice wine'. Traditionally, ice wine is made in the cooler regions of central Europe and Canada from grapes that have been naturally frozen on the vine. Otto is making a similar style of dessert wine by freezing late picked Chardonnay grapes overnight in a commercial freezer at -16C. The fruit, which was at 13.0º baume sugar levels prior to freezing, was then quickly pressed the following morning at a high pressure.
