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.
A French term referring to a viticultural problem in which grape bunches contain berries of greatly differing size and levels of maturity. Caused by cool weather during flowering.
(France) This term describes the failure of some grapes in a normal bunch to fully develop. The result is uneven berry size. It is caused by cool weather during flowering.
A condition resulting from poor or incomplete pollination, in which the bunches contain fewer-than-normal, scattered berries. May result in a "poor set" in such cases. Yields can be drastically reduced over normal.
Millerandage is a French term referring to an viticultural problem in which grape bunches contain berries of greatly different size and, most important, different levels of maturity. Its most common cause is too cold or otherwise bad weather during the flowering stage of the vines. The condition causes lower quality in affected wines, which are often French or German.
