Rosenthal Malibu Estate is experiencing a very cool summer. Even with the current heat spell, most fruit in the area (and state-wide) will be late this year. However, RME is situated in a warm area of the Malibu/Santa Monica Mountains which aids in ripening, even in a cool year.
Crop levels are always adjusted at RTME for maximum quality, and in those blocks with more fruit than desired we are now dropping clusters.
With all the rain and fog this spring and summer, we have needed to be diligent in our treatments for both mildew and botrytis bunch rot. At this time infections of both are minimal. Many vineyards have battled, and will continue to be threatened by both this season. To date, the dreaded European Grapevine Moth has not been found in LA County. Its spread is being closely monitored in every county. Expert opinions are that control will not be difficult, even with organic means, if found. This is the first time is has been found in North America. Invasive species continue to threaten all agriculture, and wine grapes are no exception.
With the wet winter, we have many blocks that have not needed any irrigation, even through July! Our wells are recharged, and the soil moisture content was perfect as the vines grew through the spring. Rains like we had this year help to leach salts that accumulate during irrigation and dry years as well. I have blocks I will not irrigate at all this season, "dry farming" through harvest.
The market for grapes state-wide is very difficult for growers. With production of high quality Coastal fruit up, and consumption of mid priced wines down, growers are hoping we will all drink more wine!
Until next time,
