Italian term (withering, wilting) for the drying of grapes. These are laid out or hung on wooden racks in well-ventilated attics or in the open air. If necessary, this is supported by fans to prevent rotting. This can last from a few weeks to several months. The loss of water in the berries results in a higher concentration of sugar and flavour, thus enabling the production of sweet wines. This is used in the wines produced using the Passito and Recioto methods.
I have great respect for the scope and quality of the wein.plus encyclopaedia. It is a unique place to go for crisp, sound information on terms from the world of wine.
