Fruit Set What Happens During Fruit Set?
One of the early season viticultural challenges of Pinot Noir is its susceptibility to “shatter”. So, what exactly is shatter?
Grape shatter occurs when a grape cluster fails to develop fully during the spring bloom period. It is during this time that the grapevine flowers are pollinated and develop into infant, tiny berries. Fruit set can be dramatically affected by weather conditions during budbreak — rain, wind, or extremes in temperature can trigger incomplete fruit set and result in shattered clusters. If clusters are affected during flowering, either not all flowers on a cluster are pollinated, and therefore never develop into berries, or the tiny berries fall off shortly after formation. This is often referred to as a “poor fruit set” and can significantly limit the crop yields for the coming season.
Pinot Noir, grown in cooler, more extreme sites than most varietals, is extremely vulnerable to shatter in years of poor early season weather. One of the many advantageous characteristics of the Boars’ View estate is its optimal sloping hillside disposition with full sun exposure. Allowing the cooler, damper air to naturally flow away from the delicate vines, the Boars’ View fruit is beneficially protected from the malicious threat of grape shatter. As a result, the Boars’ View fruit fully sets, leading to developed clusters with optimal skin to juice ratio for enhanced flavor development – every winemaker’s dream.
