Puglian Olive Oil and the Frantoio: The Engine Under Every Masseria

Before Puglia made hotels, it made oil, and it still makes more of it than anywhere else in Italy. The olive grove is the regional landscape and the regional economy at once, and it's no accident that nearly every masseria in this guide turns on it: Moroseta and Mascienda press their own organic oil, Potenti and Torre Coccaro farm groves that are eight hundred years old, and Trapanà and Torre Maizza built their spa inside the old olive mill itself. To understand a Puglian masseria, start with the trees.

And the trees are extraordinary — gnarled, hollowed, half-sculptural, the oldest of them well past a thousand years and protected by law as ulivi monumentali, monumental olives, concentrated on the plain below Ostuni in the aptly named Piana degli Ulivi Monumentali. The fruit changes character as you go: the robust Coratina and Ogliarola of the center, the Cellina di Nardò down in the Salento, each pressed into a different oil.

The frantoio — the olive mill — is the working heart of a masseria, and in the old days it was often dug underground, a frantoio ipogeo cut into the rock so the temperature held even and the paste never chilled. Gallipoli, down on the Ionian, grew rich on exactly this: its hypogean mills pressed the lampante, the lamp-oil that lit the streetlamps of Europe before gas arrived, and shipped it out of the port by the barrel. Many of those underground mills survive, and a few masserie — Trapanà's spa among them — have given theirs a quiet second life.

There's a sadness in the groves too, and it's worth knowing. Since around 2013 a bacterium called Xylella fastidiosa has worked its way up from the southern Salento, killing millions of old olive trees and leaving long stretches of the deep south standing in grey skeletons. The region is replanting with resistant varieties and fighting to save the oldest trees, and it's part of why the surviving ancient groves — the ones you'll walk through at these masserie — feel less like scenery and more like something to be grateful for.

Good Puglian oil is grassy and peppery, with a bitter catch at the back of the throat; that catch is the polyphenols, and it's a sign of quality, not a flaw. Most of the masserie sell their own — buy it at the source, ask which grove and which pressing it came from, and if you're there in late autumn look for novello, the cloudy, just-pressed oil of the new harvest. For a name to carry home beyond the hotel gate, the Antico Frantoio Muraglia, up near Andria, has milled Coratina oil since 1850 and bottles it in hand-painted terracotta thrown by local potters — the jar alone makes the argument for Puglian craft. It is the one thing from this trip that will still taste like Puglia when you open it at home.
