Hand vs Mechanical Harvesting

Behind the Bottle: Hand of Mechanical Harvesting, Which is Better?As you drive around the North Fork, you likely will see many teams out in the vineyard working to ensure the grapes ripen to their full potential throughout the growing season. While often an overlooked component of the winemaking process, good vineyard management is essential to good winemaking.

A wine is only as good as the grapes it comes from and good vineyard practices throughout the year mean less intervention and a more hands off approach can be taken by the winemaker and the winemaking team once the fruit arrives at the winery. 

There are two main ways to harvest grapes, by hand and by machine. At Suhru, we hand harvest the majority of our grapes. The decision to hand harvest vs mechanical harvest depends on a multitude of factors including the grape varietal, condition of the grapes, and style of wine you are trying to make. Let's explore the differences!

 

 

Mechanical Harvesting in the Suhru VineyardMechanical Harvesting

For many grape varieties and styles, particularly early ripening white wine grapes, mechanical harvesting is a more efficient and cost effective approach. In mechanical harvesting a harvester machine straddles the grape vine, gently shaking the vine which dislodges the berries dropping them into a conveyor belt that carries them to a holding bin. When the harvester reaches the end of the row the holding bin is emptied into a gondola which then transports the grapes to the winery to be loaded into the press.

Mechanical harvesters are a great option for larger vineyards that lay on flat level ground. They can very quickly harvest an entire block of fruit and get it to the winery and loaded into the press in a fraction of the time it would take to hand harvest the same block.

At Suhru we machine harvest our Pinot Grigio. The vineyard where it is grown is well suited to a mechanical harvester and it allows our early ripening Pinot Grigio berries to arrive at the winery very quickly after being harvested which is important for machine harvested fruit as the berries are often split open during the harvesting process.

Hand harvesting, while extremely labor intensive, allows our vineyard team to examine the fruit as they move through the vineyard, selecting only the best grape clusters and discarding the bruised, damaged or underripe fruit. A skilled hand harvester can pick between one and one and a half tons of grapes in a 10 hour day, which is the equivalent of 800-1,200 bottles of wine or 66-100 cases.

While more expensive, laborious, and time consuming there are a number of reasons to hand harvest your grapes:

  1. Allows for more precision. The grapes are better protected during harvesting greatly reducing the possibility of oxidation due to damaged skins. 
  2. Winemaking Style. For a number of styles including méthode champenoise and some styles of white wine we whole cluster press, meaning that the entire cluster, stems, seeds, skins and all are loaded into the press and discarded as one once the juice has been pressed out.
  3. Fruit quality. When you machine harvest all the berries are mixed in however when you hand harvest as the vineyard crew is moving from cluster to cluster they can pick out any berries damaged by birds or any that have not fully developed ensuring that only the best berries make it to the winery. 

We would like to take a moment to applaud the hard working men and women who cultivate and care for our grape vines throughout the year. THANK YOU for all that you do, we could not do it without you!
