The projected future warming at the global, continent and wine region scales will likely continue to have both beneficial and detrimental impacts by opening up new areas with increasing viability to viticulture, or by severely challenging the ability to adequately grow grapes and produce quality wine. Observations from the Douro region reveal higher growing ...
ABSTRACTThis study aimed to establish if there is any evidence that soil mineralogical and/or chemical composition influence the composition and quality of wine grapes. In the initial phase of the study, soils and grapes were sampled in two riesling vineyards in South Australia. Soils were analysed for a wide range of total major and trace ...
