Harvest Report 2012

The South African wine industry is excited about a particularly promising wine grape crop, both in terms of quality and volume. The harvest season was characterised by healthy, ideal growing conditions and a cool, though lengthened, harvesting period without rain or prolonged heat.

Inland wine growing areas recorded some of the best crops ever, while dwindling water supplies in the coastal region caused a systematic decrease in the anticipated crop over the season. The consequences of flood damage in the Orange River region in 2011 are still evident.

The total crop estimate exceeds that of 2011, and high quality wines are anticipated for the 2012 wine grape crop. The South African wine industry is able to buffer large fluctuations in overall crop size and quality, thanks to the diversity of the respective cultivation areas.

Crop size** – The 2012 wine grape harvest is expected to amount to 1 405 845 tons according to the latest estimate (30 April) of the SA Wine Industry Information and Systems (Sawis). This exceeds the 2011 crop by 8% and is only 10% smaller than the overall record crop of 2008. Paarl, Malmesbury, Stellenbosch and the Orange River will have smaller harvests, while the rest of the nine districts expect record harvests.

The 2012 wine harvest – including juice and concentrate for non-alcoholic purposes, wine for brandy and distilling wine – is expected to amount to 1 085 million litres, calculated at an average recovery of 772 litres per ton of grapes.

2011/12 Growing season – The 2012 season kicked off with sufficient cold, but a drier winter than usual – in the coastal regions especially. Sufficient cold units had accumulated by the end of June, and with August being warmer, bud burst was a week early in some blocks. Vineyards showed good growth in the ideal weather conditions at the start of the new growing season.

Abnormally cold and rainy conditions during the second part of flowering resulted in uneven flowering and berry set, with high disease pressure, which producers managed to control satisfactorily.

Weather conditions were back to normal in December, and less wind than usual resulted in less damage to grapevines than previous years. January was exceptionally hot, with heatwaves resulting in sunburn damage in some instances. This exacerbated pressure on dryland vineyards, which already had little soil water resources at that stage.

The ripening period in February and March was further characterised by ideal, cool weather conditions for slow ripening, resulting in good colour and flavour in red cultivars especially. Very dry weather also contributed to healthy grapes and the absence of diseases and rot.

Cooler weather delayed the start of the harvest by about two weeks and the last grapes were crushed two to three weeks later than usual.

Wine potential – Producers, viticulturists and winemakers are excited about the quality of this year’s crop, and some districts expect the best quality in years. The cool harvest period and slow ripening resulted in smaller berries with intense colour and exceptional flavours – in the red cultivars especially – as well as optimal ripeness levels at lower sugars, which led to lower alcohol levels. Throughout the industry winemakers anticipate excellent white wines with good fruit and structure.

Breedekloof – An ideal year in terms of size and quality, with exceptional red wines.

Klein Karoo – An unequalled vintage, to be remembered for being huge, late, and healthy with exceptional quality.

Malmesbury – Despite dry conditions and a subsequently smaller crop, high quality wines, whites especially, are in the pipeline.

Olifants River – One of the better vintages, with bumper yields and good quality following a very temperate season.

Orange River – Quality is good throughout, but the crop is considerably smaller, with the impact of the 2011 floods still evident, and dual purpose cultivars being used for raisins.

Paarl – A slightly smaller crop due to dry weather conditions and a cold flowering period. Quality is nevertheless expected to be excellent, in the red wines especially.

Robertson – An incredible vintage with healthy weather conditions, a record crop and exceptional quality.

Stellenbosch – Limited water resources and adverse conditions during flowering resulted in a smaller though top quality crop without green flavours.

Worcester – An exceptional growing season culminated in a record crop with exceptional white and red wine quality.
