Tradicionalmente los Brandis de Jerez se elaboran con destilados o aguardientes de vinos de la variedad Airén. Sin embargo, algunas bodegas del marco de Jerez están apostando por la elaboración de Brandis a partir de la variedad Palomino fino, mayoritaria en el marco de Jerez. En este trabajo se ha estudiado la composición química y se ha realizado el análisis sensorial de mostos, vinos y destilados procedentes de uva de la variedad Palomino fino cultivada en tres tipos de suelos diferentes: albarizas, barros y arenas. Los mostos de la uva cultivada en albarizas presentaron mayor grado sacarimétrico, más acidez total y menor pH. Consecuentemente con los mostos de partida, fueron los vinos procedentes de la uva cultivada en suelo de albarizas los que presentaron mayor grado alcohólico. Los vinos procedentes de la uva cultivada en suelo de barros presentaron más concentración de acetato de etilo y de n-propanol. Sensorialmente los vinos mejor valorados fueron los procedentes de la uva cultivada en suelo de barros. Respecto a los destilados, los mejor valorados sensorialmente fueron los procedentes de uva cultivada en suelo de albarizas.
Abstract
Brandies are usually elaborated from white grapevine Airen. However, wineries are currently trying to wide the brandies production testing other varieties. Palomino fino variety is mainly cultivated in albarizas soil, and in minor proportion in mud and sandy soils. In the current work, the analytical composition of Palomino fino musts, wines and distillates, which have been cultivated in albarizas, mud and sands soils, has been studied. The must from grape cultivated in albarizas soil highlighted for showing high sugar content and total acidity, meanwhile the pH the lowest value. The wine come from grape cultivated in albarizas showed the highest ethanol content, in agreement with sugar content in the must. The wines from the grapes grown in mud soil had a higher concentration of ethyl acetate and n-propanol. In tasting, the wines come from grape cultivated in mud soil obtaining the highest score in fruit aroma intensity. Regarding distillates, those come from albarizas soil showed the highest scores.
