There is an extremely prestigious vineyard in the Italian region of Valle d'Aosta where Maison Anselmet currently produces its delicious "Prisonnier" wine. There are only one thousand bottles of Prisonnier available at the moment, and their price can rise up to 600 euro. Their special taste comes from the impressive vine age/density combination (60 years old/10,000 vines per hectare), and from the fact that these vineyards are embedded in a rocky wall offering Prisonnier's grapes the chance to experience everyday a double temperature range. Prisonnier bottles are very prestigious now, and they have also proved wrong all those wine specialists arguing that grapes cannot grow in the mountains or near glaciers.
