My recent visit to Antinori’s Tignanello property in Chianti Classico provided an object lesson in the challenges of understanding the complexities and nuances of Tuscan terroir, something that can be extrapolated to many other regions within Italy as well. I saw vineyards where the two major terrains in these hills, galestro and alberese, alternated in groups of three to four rows within the very same plot. As a result, vines that were separated by no more than a few meters were at slightly different points in their vegetative cycles, meaning that work in the vineyards must literally proceed on a row by row, and sometimes, plant by plant basis.
