Vinsanto - Grapes and Wine

Grapes and Wine

The island of Santorini is most famously known for its indigenous white grape varieties Assyrtiko, Athiri and Aidani, though some wines made from international varieties and also from indigenous red grapes such as Mandalieria and Mavrotragano can be found. About 1,200 hectares of land are under vine, however, there is a constant struggle with Santorini's tourism industry that puts this small number at risk of decreasing even further.

Assyrtiko is the island’s flagship grape. It’s a high acid grape full of citrus and mineral nuances. It can be enjoyed on its own or with grilled fish and meats. The grape is often referred to as a “white grape in red’s clothing,” due to the full-bodied wines it produces with an average of 13.5% abv.

Santorini is immune to phylloxera as its volcanic soils contain none of the clay that is necessary for parasite to survive. As a result, many of the roots found on the vines on Santorini are centuries old. The grape growers of Santorini use a unique bush-training system, known as koulara, to grow the grapes. As the vines grow, they are woven into baskets with the grapes facing toward the inside of the ring. The vine’s leaves and vine provide protection for the grapes from harsh winds and sunlight. The koulara are often grown haphazardly on small plots of land and can be mistaken for wild bushes by unknowing passers-by. Grape varieties are frequently grown together and the growers are often unaware which grapes are which until harvest which takes place in mid-August.

At the age of 75 a vine is generally woven into many layers and it may be unable to provide proper nutrients and high enough yields to keep in production. As a result, it is clipped at its roots and a new vine is connected to the rootstock. It is important to keep the roots healthy and in use as their old age has allowed them to grow deep into the calcareous soils, extracting any moisture that may be available.

Santorini classified wines: Santorini, Nykteri and Vinsanto (see below for Vinsanto information.)

Santorini: This wine must contain 75% or more of the Assyrtiko grape variety with the remaining 25% made up from Athiri and/or Aidani. The wine is generally unoaked, but some wineries choose to make a small portion of oaked wine due to Assyrtiko’s versatility. Either way has a great gaining potential due to the high acidity of the grapes. The wine is bone-dry with high acid toting flavors of lemon and stone fruits with a distinct taste of minerality.

Nykteri: In Greek, the name means “working the night away” as it was traditionally harvested at night to avoid the hot temperatures and create a fine wine with little extraction from color and exposure to air. The grapes were to be picked before sunrise and pressed and drawn off within the first day. Today, many producers still choose to harvest the grapes at night, but some also harvest during the day. It is at least 75% Assyrtiko with the remaining composition allowed to derive from Athiri and Aidani. After vinification in steel or oak, Nykteri wines must be aged in oak for a minimum of three months. These wines are bone-dry and contain high acid and mineral components bringing forth flavors of citrus and stone fruits.

Mezzo: Although this wine is not part of Greece’s classification system, it is a wine commonly produced. This is a sweet wine made from the island’s white or red grapes and is similar to Vinsanto, but literally means "less sweet." The grapes are also sun dried, but before vinification dry grape must is added to the run-off juice from the raisoned grapes.
