Rèze is a white Swiss winegrape variety that is primarily found around the city of Sierre in the cantonofValais in southwest Switzerland.[1] Here the variety is used to produce vin des glaciers—a sherry-style wine that utilizes a solera system of wine stored in larch wood or oak barrels that are never fully emptied with newer vintages being added to the barrels containing the older vintages.[2]
Despite its historical use in the production of vin des glaciers, its plantings have nonetheless been declining over the last century and now the variety is almost extinction.[1]
