Sorry, no etymologies found.
However, the Bordelais did not replant carmenere because it is susceptible to coulure, also known as "shatter," a metabolic condition triggered by wet, rainy conditions that cause grapes to fail to develop after flowering.
Sensitivity to frost and proclivity to shatter or coulure (a disease that results in premature fruit drop) is the primary reason that Malbec has become a decreasing factor in most of France.
Dourthe reported that the weather settled down during May, encouraging good growth, but rain and cold at flowering caused widespread coulure (failure to produce fruit) and millerandage
Cool and damp conditions caused widespread coulure (failure to produce fruit) in Muscat Ottonel in particular, dramatically lowering yields.
Less wine will be produced in 2009 due in part to coulure - or shattering - during the June flowering period, when cold rainy weather resulted in less and smaller grapes per bunch.
The downy mildew threat was high here in the north of the Médoc, but as far as coulure was concerned, apart from old vines which are very prone, we were much less affected than in other appellations.
