Hybrids or PIWIs
Have you ever tasted a Souvignier Gris, a Solaris or a Bronner? What about Regent, Cabernet Cortis or Rösler? These are just some of the disease-resistant varieties that have been bred over the last few decades from complex crossings of vitis vinifera cultivars with American sub-species such as vitis labrusca, vitis riparia or vitis rupestris.
What started as a crude exercise in creating new plant material in the wake of the turn-of-the-century phylloxera catastrophe has become a cutting-edge niche in wine production. Varieties are being developed that have resistance to cold, drought, or to common vine ailments such as downy mildew and botrytis. This has opened the door to a form of viticulture that requires almost no inputs apart from pruning.
Should we call these varieties hybrids or PIWIs or something else? And how is a hybrid different to a crossing or a “direct producer”? Does laboratory crossing of grape varieties overlap with gene-splicing, CRISPR9 or GMOs? Where are the boundary lines in these techniques and what do they mean for viticulture and wine in general?
We’ll talk about why winemakers from France, Austria, the Netherlands, Italy and beyond are planting hybrids. Hybrids might just be the future in wine. So join me for this session if you want to stay ahead of the curve!
