For the last two years Alessandro Masnaghetti and I have been hard at work on a map of the Santa Lucia Highlands. Our first edition is nearly complete. Formal approval of a change in the AVA’s southern boundary is all we are waiting for to wrap things up. In the meantime, we are going take you behind the scenes in this article, which represents a summary of our work so far. It will surely be updated and refined in the coming months.
