A season of extremes in McLaren Vale

The season 2000-01 commenced with unprecedented rainfall. If ever McLaren Vale needed a wet season to replenish aquifer levels, it was this year. After a wet winter, McLaren Vale's annual rainfall topped 643.6mm for the period January to December 2000; well above the district's mean rainfall of 517.1mm (figures supplied by the Bureau of Meteorology).

Budburst in September showed much promise for all varieties, although Cabernet Sauvignon experienced early bud mite, reducing shoot growth and limiting flower development.

The winter rains were quickly utilised for early growth and some potassium deficiencies were evident, particularly in Shiraz.

Flowering proceeded unimpeded and an above average crop was set for most varieties. The powdery and downy mildew pressures early in November/December were low, giving some relief to growers.

Between December and February, McLaren Vale recorded its hottest summer for almost 100 years. The mean maximum temperature was 31.2°C; 2.8°C above average, making it the hottest summer since 1905.

Throughout the ripening period, vineyards held up remarkably well, with many underground well supplies stretched to the limit. Some 40mm of rain in the middle of March slowed ripening where larger crop levels were apparent, but ripening continued after the rain events to see these vineyards being picked some two to three weeks later than normal.

Some shrivel, particularly with Shiraz, has been experienced, concentrating flavour and sugars, resulting in some reduced crops. However, early wines at this stage look to be of excellent quality. Overall, the vintage has come quickly with many varieties ripening together and quickly over a 10-day period.

We all look forward to the first 2001 barrel tastings!
