Emilia-Romagna: The Secret Room and the Smell You Never Forget

by Joseph Harris

There is a food show in Italy called Cibus. It happens in Parma, in the spring, and it is where the Italian food industry gathers — manufacturers large and small, importers, distributors, buyers, chefs, and a certain category of person who simply cannot stay away from a room that contains this much of what they love. We fell into the last category, though our credentials from the Mercato gave us VIP access and made it official.

We had booked our flight to Italy in 2022, and our friends Victoria and John from Italian Harvest happened to mention almost in passing that they would be in Italy at the same time. The show happened to be running exactly when our tickets were stamped. This is how Italy arranges itself for the people who are paying attention. You do not plan these things. You follow the coincidence and see where it leads.

It led to Parma. And Parma led to the Po River valley, which is one of the great food-producing landscapes on the surface of the earth. The river runs east from the Alps across the broad flat plain of northern Italy, fed by mountain snowmelt, depositing the alluvial richness that makes the soil of Emilia-Romagna unlike any other. The fog that settles over the valley in winter, the particular humidity of the air, the specific temperatures of the cellars and drying rooms — none of this was engineered. It was discovered, over centuries, to be exactly right for making things that could not be made anywhere else. Parmigiano-Reggiano. Prosciutto di Parma. Aceto Balsamico Tradizionale di Modena. Three of the greatest food products in human history, all of them from the same river valley, all of them the result of the same patient understanding that time and place and method are not separate considerations. They are the same consideration.

The show gave us access to the factories. On the last day of Cibus, they organize tours — the Reggiano, the prosciutto, the balsamic — and we went to all three.

The Parmigiano factory first. You dress in the disposable coveralls, the hair covers, the whole protocol of a place that takes cleanliness seriously because it has to. And then you walk into the production floor and watch experts moving enormous wheels of curd, shaping and pressing and turning what will eventually become something that costs more per pound than most cuts of meat and is worth every cent. Then they take you into the aging room.

Floor to ceiling, in every direction, Parmigiano-Reggiano wheels stacked on wooden shelves in the cool, still air. Thousands of them. Each one stamped with its date and its producer's mark. Each one being turned by hand, or by a robot that moves between the shelves like a slow and deliberate ghost, because the turning cannot be skipped and the schedule cannot be rushed. A minimum of twelve months. The serious wheels go twenty-four, thirty-six, forty-eight. The flavor deepens with every month into something that has no equivalent — crystalline, complex, savory in a way that the word umami was invented to describe but does not fully capture.

The smell in that room is the smell of Parmigiano — the smell you know from every kitchen you have ever cooked in — but amplified beyond anything you could imagine if you had not been there. It fills the room, fills your lungs, fills something deeper than your lungs. It is the smell of time made edible. You do not forget it.

The prosciutto factory was smaller, older, built over an underground river. This detail matters more than it sounds. The factory has a room they call the secret room, and you are not permitted to photograph anything inside it. This is where their finest products hang — the prosciutto di Parma in its long-legged glory, and something called culatello, which is the pork shoulder rather than the ham, processed in the same way but with a texture closer to lox than to prosciutto, softer and more silken, a product that almost never leaves the region because there is never enough of it and the people who know about it buy it before it can travel.

The secret room has an exterior wall that faces south. The warmth of the southern sun creates a natural convection against the cool north wall that faces the rest of the factory. Below the floor, accessed through a grate, is the underground river, which humidifies the room to exactly the level the prosciutto requires. No electricity needed. No climate control system. No engineer designed this — or rather, the engineer was centuries of trial and observation, and the solution was the building itself, oriented correctly on its site, built over the right river, open to the right wall of sun. It has worked this way since long before electricity was available to complicate it. The simplest systems are the ones that last.

We had lunch there. They fed us prosciutto until the idea of stopping seemed impolite.

I had, at that point, been thinking seriously about starting a wholesale import business — twenty or thirty products from very particular processors, the kind of relationships you build over years rather than through a catalog. This factory would have been my prosciutto supplier. I still think about that. Some doors stay open in the imagination long after the practical moment has passed.

Then Modena, and the balsamic. The factory has a cask called Hercules, the largest wooden cask in the world, which ages balsamic in bulk the way a serious winery ages its reserve. The standard aged balsamic you buy — the good kind, the kind that is actually worth buying — spends approximately five years in wood. But here is what they taught me that I did not know: the aging is not measured in years. It is measured in specific gravity. The balsamic is done when it is thick enough, when the density of the liquid reaches the correct point. This takes roughly five years, but it might take a little more or a little less, and the calendar is not consulted. The product decides when it is ready. You cannot argue with it.

The traditional balsamic — the Aceto Balsamico Tradizionale, which carries its own DOP and its own completely different price point — is another matter entirely. This is made in a progression of barrels, typically six to nine of them, each one smaller than the last, each one made from a different wood — oak, chestnut, cherry, mulberry, juniper — because each wood contributes something to the flavor that the others cannot. Every year, some of the contents of the first barrel are moved to the second, some of the second to the third, and so on down the line, until what comes out of the last and smallest barrel has passed through every wood, absorbed every influence, concentrated through evaporation into something that is no longer exactly a condiment. It is closer to an essence.

None of these barrels are ever emptied. The last barrel always retains some of what came before, which means that some portion of what you taste in a bottle of traditional balsamic could be decades old. In a family that has been making it across generations, the vinegar in the last barrel carries the work of grandparents and great-grandparents. The barrels are inherited through wills. They are listed alongside the house and the land and the other things worth passing on. This is not sentiment. This is how the flavor works. You cannot make traditional balsamic from scratch. You can only continue what was already begun.

The smell of a room full of aging balsamic is the smell of balsamic — the sharp sweetness, the wood, the concentrated grape must reduced by time into complexity — but amplified beyond anything you could have imagined before you stood in that room. The same was true in the Parmigiano aging room. The same was true in the prosciutto factory. Emilia-Romagna has a smell, and it is the smell of patience. Of things made correctly over time, without shortcuts, by people who understood that the method is not separate from the result. The method is the result.

Tonight we cook from that valley. The protein is pork — because in Emilia-Romagna, the pig is the biography of the region. Prosciutto in the antipasto, thin as paper, with melon because the combination is as old as the hills above Parma and as correct as anything on the Italian table. A proper ragù bolognese in the primo, which is not the meat sauce the rest of the world thinks it knows — it is slower and quieter and more careful than that, built on soffritto and patience and a very small amount of tomato, finished with whole milk the way the Bolognesi have always finished it. Pork braised as the secondo, because one protein, done completely, tells a more coherent story than two proteins competing for attention. And a dolce from the region that closes the meal with the same combination of simplicity and quality that Emilia-Romagna has been offering since before it had a name.

The balsamic goes on everything it improves, which is most things. A few drops at the end. Not the bulk-aged product — for this, you want something serious. A little goes a very long way, which is part of what makes it worth the price.

Chi mangia bene vive bene. In Emilia-Romagna they do not say this as a philosophy. They say it as a statement of fact, backed by centuries of evidence stacked floor to ceiling in rooms that smell like time.
