Rioja Alavesa?s 2017 harvest was an exceptional one. High temperatures during early spring led to an early sprouting and greater vegetative growth than usual. However, a frost towards the end of April caused extensive damage to many of Rioja?s vineyards. Cold air remained at the bottom of the valleys, so vineyards located higher in altitude were not as affected. High temperatures during summer and the subsequent drought led to an earlier and shorter harvest than usual. It lasted from September 20 to October 2, whereas on average it begins after October 12. Despite the irregularities, wine quality was exceptional, with excellent colour, structure and very sweet ripe tannins.
