Modern Disease-Resistant Grape Varieties for the 21st Century - Part 1

Modern viticulture places an increasing emphasis on sustainability and a low need for chemical protection. It is in this context that modern resistant (interspecific) varieties of table grapes are coming to the forefront. They are the result of targeted breeding that combines the excellent taste of classic varieties with an innate resistance to fungal diseases and frost.

In this installment, I will introduce four prime examples of this trend – Alvika, Alibaba, Alfa, and Ajuta. They are the ideal choice for more ecological cultivation without compromising on taste or the size of the harvest.
