The growth cycle began favourably thanks to abundant rainfall in the Autumn of 1992. Budding was very good, with a good show of small clusters and normal fertilisation levels for all varieties, except for Garnacha in Rioja Baja where there was a certain amount of coulure. In general, the vineyards looked good in late July. The 1993 vintage was defined to a certain extent by the weather in August. A heat wave which affected the whole of the Region with highs of 33-40 °C, accompanied by hot, easterly winds, resulted in the wilting of Tempranillo leaves and a stop in the growth cycle in some areas of Rioja Baja. Thunder storms during the last week of August and a sudden drop in temperatures paralysed veraison and favoured the appearance of some outbreaks of botrytis.
Harvest began during the last week of September. In Rioja Alta and Alavesa, the grapes affected by Botrytis showed high alcohol contents due to berry dehydration. As the harvest progressed, the quality and the alcohol potential of the healthy grapes increased.
Irregular weather during the 1993 harvest resulted in significant variability among the wines obtained. Although wines considered as "correct" by the Rating Committees predominated, some outstanding wines were obtained from grapes picked at certain stages of the harvest which were not affected by the heavy rainfalls. These wines were kept by most bodegas to produce Crianzas, Reservas and Gran Reservas
