I have a small vineyard (25 vines), and experienced berry shrivel last yr and this yr. My vines are 4 yrs old and so far I have only seen the shrivel in two vines and not on every bunch. No one else has explained this event as well as your article has so thank you. At least I know someone is working on this problem. I'm hoping it will not get any larger than it currently is because this is my second harvest and right not I have a lot more grapes than last year. And, if they don't shrivel and the birds don't figure out how to get into the nets, I could have a pretty good harvest.

I only have a few nice vines . However, this is the second year I have berry shrivel, but don't know what to do. Would appreciate your advice. Thank you.

I have seen this many times in many sites for many years. Not the same AVAs ,  
not the same age vines, or the source of vines, different rootstocks but always Cab Sauv.  
Frankly less likely in blocks planted with the old FPMS clonal material. More likely with  
the newer clonal material like the 337 and such.
