Notes from Regal Wine Imports:

The Colli Tortonesi in Piedmont is home to the glorious white grape called Timorasso. From Monte Giarolo at 1473 meters, five valleys and their rivers have formed over the centuries to encompass today’s Colli Tortonesi. Each valley has its own distinct micro-climate, yet the subzone of Libarna [LEE-barn-a] in Val Borbera remains the most extreme. Here lies Ezio Poggio winery and vineyards.

Cupped by the Apennines’ northern most reach, amid abandoned Roman ruins and overgrown forests, Libarna imbues an ancient silence. It’s the most southern growing area of the Colli Tortonesi, yet it has the highest elevation by far, topping out at 650 meters. Winds howl on the limestone, marl, and clay soils; temperatures drop to 10/15 °C during summer nights. Ezio Poggio is the only producer currently bottling here, with his first vintage being 2008 after four years of propagating vines from massale
selection.
