On a cold fall day I made my way up into the hills above Mercatale Valdarno in search of Podere Il Carnasciale. The unpaved winding roads pass through the adjacent Petrolo estate in this very rugged corner of the Tuscan landscape rich in forests. I followed my hand-written directions diligently and when I saw the small house at the end of the road I knew I had arrived. I was greeted by owner Bettina Rogosky and oenologist Peter Schilling, both of whom seemed relieved I had actually made it.
