If you could see the way grapes are grown on the Greek Island of Santorini, you might be skeptical about the production of wine. They are grown in basket-like clusters rising only about a foot from the ground; no arbors needed. And if you knew that it rarely rains at any time during the year on this island, you would be even more skeptical. The grapes go it on their own, absorbing whatever moisture they can gather from sea breezes or from digging ever deeper into the alluvial soil. The "vines" are indigenous, pre-philloxera and have been producing wine grapes continuously for hundreds, if not thousands of years, with some time off for recovery from the volcano that devastated the island in 1600 BC.
Of course, all of that is positive for the wine, if not entirely so for anyone wishing to make money from selling the wine. Yields are low and flavor concentration in the grapes is extremely high.
We spent an afternoon at Santo Winery, and their five-wine tasting flight was relatively expensive compared to other prices on the island but worth every sip. We had three Assyrtiko-based whites, one red and one naturally sweetened wine, Vin Santo.
The first wine, Santorinio Assyrtiko, went through what the winery called "classic white winemaking," which basically meant without oak aging. Citric and floral with sea breeze tones and that intense mineral edge. Has probably had some lees contact.
Santo Wines Santorini Nykteri was 85% Assyrtiko with 10% Athiri and 5% Aidani--all from Santorini. It was aged for six months in French oak vats. Slightly deeper in color and richer on the palate. Citrus, green apple and pear with Assyrtiko minerals and a glorious finish.
Assyrtiko Santorini Grande Reserve was 100% Assyrtiko aged 12 months in medium toast French oak. Deep gold, full body. Complexity you might expect from a high-level white Burgundy--roasted nuts, spices, vanilla and toast. The winery predicts "long aging potential," something I would expect from all of the Assyrtiko wines.
Santo Wines Santorini Mavrotagano Dry Red Wine is 100% Mavrotagano aged 12 months in medium toast Frrench oak barrels. Ruby color. Intense red and black fruits. Tannins are showing on this wine and I would wait a few years before opening a bottle. I preferred some of the red wines I had in Athens, especially those made with Xinomavro.
Vin Santorini is a gorgeous sweet wine, similar to Amarone, made from sun-dried grapes. It is 85% Assyrtiko and 15% Aidani, sun dried for six to eight days followed by slow fermentation and at least 36 months in French oak barrels. Dried fruits and nuts. Very concentrated. Long, long after taste. Reminds me of a 20-year Tawny Port, although, unlike tawny ports, this wine will continue to age in the bottle. The 12- and 20-Year Vin Santo Wines were available at the winery but, unfortunately, not included in the tasting.
