Erratum Erratum The authors of the paper ‘An ethanol spray at veraison enhances colour in red wines’, Christian Chervin, Ashraf Elkereamy, Jean-Paul Roustan, John D. Faragher, Alain Latche, Jean-Claude Pech and Mondher Bouzayen, AJGWR, 7(3), 144–145 have advised us of an error that had been overlooked in their manuscript. In the second line of the paragraph on ‘Results and discussion’, the words ‘50 berries’ should have read ‘20 berries’. The corrected paragraph should read as follows. Results and discussion Ethanol spray did not change berry weight significantly. At harvest the weight of 20 control berries was 22.17 ± 0.55 g compared with 21.93 ± 1.16 g for ethanol-treated fruit (mean ± SE, n = 3). By contrast, we observed that 5% ethanol rapidly stimulated internal ethylene concentration in grapes (Figure 1a). We also observed that grapes sprayed with ethanol accumulated higher levels of red pigments in berry skin (Figure 1b). Similar results were obtained over two consecutive years with different vines and different weather over the month prior to harvest. Optical density (OD) at 520 nm is a good indicator of anthocyanin concentration, although other factors influencing colour, including co-pigments, may have been altered by the ethanol spray. While acknowledging that issue, we note that the colour intensity of one-yearold wines made from ethanol-treated grapes was greater than that from controls (Figure 1c). This is an important outcome because colour stability is a major quality factor of red wines. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Australian Journal of Grape and Wine Research Wiley

Abstract

Erratum The authors of the paper ‘An ethanol spray at veraison enhances colour in red wines’, Christian Chervin, Ashraf Elkereamy, Jean-Paul Roustan, John D. Faragher, Alain Latche, Jean-Claude Pech and Mondher Bouzayen, AJGWR, 7(3), 144–145 have advised us of an error that had been overlooked in their manuscript. In the second line of the paragraph on ‘Results and discussion’, the words ‘50 berries’ should have read ‘20 berries’. The corrected paragraph should read as follows. Results and discussion Ethanol spray did not change berry weight significantly. At harvest the weight of 20 control berries was 22.17 ± 0.55 g compared with 21.93 ± 1.16 g for ethanol-treated fruit (mean ± SE, n = 3). By contrast, we observed that 5% ethanol rapidly stimulated internal ethylene concentration in grapes (Figure 1a). We also observed that grapes sprayed with ethanol accumulated higher levels of red pigments in berry skin (Figure 1b). Similar results were obtained over two consecutive years with different vines and different weather over the month prior to harvest. Optical density (OD) at 520 nm is a good indicator of anthocyanin concentration, although other factors influencing colour, including co-pigments, may have been altered by the ethanol spray.
