The volume, composition and organic load of wastewaters from five wineries producing white, rosé and red wines bythermovinification, as well as traditionally vinified red wines (75 000 hL to 240 000 hL wine), were studied in termsof the vinification metho... see more
Characteristics of Chardonnay and Pinot noir vines on Richter 99 (99R), Richter 110 (110R), Ruggeri 140 (140Ru)and SO4 rootstocks were assessed over six consecutive seasons in a factorial field trial on an Avalon soil in Stellenboschthat had been limed to... see more
