PIWI – an idea whose time has come?

Outside Germany, the acronym PIWI – short for Pilzwiderstandsfähig: German for ‘fungal-resistant’ is not very widely known. Effectively describing what used to be known as hybrids, it describes crossings between Vitis vinifera and other strains of Vitis that have been specifically developed – mostly in Germany and Switzerland – to need fewer treatments and potentially provide higher and more reliable yields.
