Notes from the 2019 Cabernet Franc Wine Tasting and Evaluations

Hemant Gohil, Gary Pavlis, and Daniel Ward

A Cabernet Franc (CF) wine tasting and evaluation workshop for winemakers was held on November 25, 2019, at Unionville Vineyards, located in Ringoes. Cabernet Franc (CF) is one of the most suitable Vitis vinifera varieties for New Jersey with high-quality wine production, for both north and south New Jersey1. It is also one of the best red varieties for New Jersey in terms of consistency in ripening. It can be easily adapted in the winery for Rosé, dry still varietals, and in red wine blends. The responses to a survey sent two weeks before the event, formed the basis of discussion at the workshop. Winemakers also described how they accomplished each of their wines. [Read more…]

By Daniel Ward and Hemant Gohil

It is harvest season and one of the most challenging aspects of wine making is upon us – When to harvest? There is no single combination of physical, chemical, flavor and aromatic composition of grape berries that can be used to decide when to pick, so we need to use our best information and exercise our best judgment.

Wine Grape Downy Mildew Update

By Peter Oudemans

June 4-6 and June 12 showed some significant downy mildew infection periods and we are now beginning to see the effects.  Since berries are susceptible until about a month after capfall this is something we need to be concerned about.  The question is how to handle this now?

Rules: 

  • Hitting the target: Make sure the sprayer is set up to hit the target.
  • Longevity:  Fungicides work best if they can dry after application.  Rainfall before drying will wash them off
  • Resistance:  Downy Mildew is a high risk pathogen and fungicides must be rotated
