Recommendations:
May be vulnerable to Crown-gall disease. Reported to have good resistance to fungal diseases. Fruit clusters require proper thining. Do not use sulfur.
Winery  
Considerations:
Used to make quality red wines with spicy aromas, fruity flavors and some herbaceousness. Somewhat low in tannins so can benefit from extended skin contact during fermentation. Intense dark wine with peppery flavors. Good as a "coloring agent" when blended with other wines.
