The 19th-century homes in old Tbilisi neighborhoods were built in a style Georgians call “Italian Courtyards,” where through a gate or arch you enter a quad enclosed by stories of balconies shared by each family on the floor. This courtyard was the nucleus of each building, where kids safely romped around, monitored by adults from the windows above, as men contemplated domino moves at a table under a tree and women beat rugs on an iron rack in a corner.

We are sitting under the tonic canopy of an enormous pine tree in a hidden Tbilisi garden, licking our lips over menu items that are neither European nor Georgian. When our dining companion informs us she will not share her trout tartare with adjika (highly concentrated spicy red pepper paste), we realize there will be no plate-dipping tonight. Just as we settle on our main courses, a woman in a blue chef’s jacket comes up to our table, beaming bonhomie, and asks if she can help us in any way. This is Tekuna Gachechiladze, the blue-eyed Tbilisi chef dedicated to changing the way Georgians understand their food culture. We are sitting at her latest culinary venture, Cafe Littera.

Ènek poured a rosy-colored splash of wine into our glasses, avidly explaining how this particular Aladasturi grape vine was meticulously cultivated in its native west Georgia. In a tasting ritual uncommon in Georgia, we swirled it, sniffed it and savored the flavor as it caressed our tongues. Here in the “cradle of wine,” the land where viticulture is believed to have originated 8,000 years ago, wine is customarily poured into a water glass and “tasted” in one long drag, until drained. But in this cozy cellar in the heart of Tbilisi’s historic Sololaki neighborhood, seven winemakers have come together to offer an alternative convention to winemaking and consumption. They call it Vino Underground, but we call it wine heaven.
