Definitions for "Millerandage"
An abnormal vine condition caused by cool weather at the flowering stage that results in grapes of greatly differing size within the same bunch. There is some evidence that in some varieties smaller grapes produce better wines, so this condition is not always undesireable.
abnormal fruit set in which bunches contain berries of very different sizes because of poor fertilisation, often because of unfavourable weather.
This term describes the failure of some grapes in a normal bunch to fully develop resulting in uneven berry size. It is caused by cool weather during during flowering and produces lesser quantities of concentrated juice.
