Yields could also be 15% to twenty% decrease within the broader area, largely as a result of smaller grapes and the truth that some had been burned by the solar in particular areas, Teitgen stated, however it gained’t have an effect on the wine’s high quality.
In entrance of the 14th-century tower of the Château Smith-Haut-Lafitte winery, Manon Lecouffe this week rigorously watered newly planted vines, an indispensable job.
Vines which might be a number of years outdated have deep roots that permit them to attract water from far underground and endure drought with out struggling an excessive amount of.
However this yr, estates had authorization to water grownup vines, a apply often banned in Bordeaux.
