Dear Dr. Vinny,

I was reading the notes on harvest from Michael Browne. What does he mean by "hens and chicks in the clusters"?

—Scott K., Charlotte, N.C.

Dear Scott,

"Hens and chicks" is when a grape bunch contains berries of different sizes and levels of maturity. The normal-sized, seeded berries are the "hens," and the small, seedless berries are the "chicks." It's believed to be caused by cool weather during flowering. (This is also known by a French term, millerandage.)

—Dr. Vinny
