The Montanera season is one of the most fascinating and important phases in the production of Iberico ham.
This period, spanning from October to February, marks the final stage of the breeding process for Iberian pigs.
During these months, the pigs roam freely across the vast dehesa pasturelands, feeding on a diet rich in acorns, grasses, and herbs. This natural lifestyle and specialised diet are key to producing the coveted Ibérico Bellota.
What Is the Montanera Season?
The Montanera season is the last phase of Iberian pig breeding, directly tied to the maturation of acorns on cork oak and holm oak trees. Beginning in mid-October, pigs are introduced to the dehesa, where they graze freely. If conditions allow for perfect feeding, the season can extend into March, providing more time for the pigs to fatten naturally!
Interestingly, the Iberian Pig is one of the very few (if not only) animals that can infuse fat into it’s muscles, and exercise is essential to help this process happen. The fat is where the flavour is, so as the fat moves into the muscle it allows the lean tissue to take on all the flavour!
For this reason, it’s extremely imprortante to give the pigs enough room to move around – free range as we say!
This phase is crucial because it determines the quantity and quality of hams and shoulders that will be available in the following season. Without the abundance of acorns, pigs cannot achieve the necessary standards to produce Ibérico Bellota-certified products.
Instead, they are reclassified into different categories, which can significantly affect their value.
How the Montanera Shapes Iberian Pigs
At the start of the Montanera, Iberian pigs typically weigh around 90-110 kilograms. Over the course of the season, they gain weight steadily, reaching an ideal range of 170 to 200 kilograms by the end.
Thats impressive growth!
The free-range nature of the Montanera means that the pigs roam the pasturelands, they cover significant distances daily, ensuring they develop muscle while layering their fat.
For pigs that fail to reach the target weight during the Montanera, alternative classifications apply. These animals are fattened on fodder until they reach slaughter weight and are then classified as “Ibérico de Cebo de Campo (actually preferred by many)” While still high quality, these products lack the prestige and depth of flavour associated with Bellota certification.
Why the Montanera Season Matters
The Montanera season is more than just a feeding phase; it’s a tradition that highlights the symbiotic relationship between Iberian pigs and the dehesa. It’s during this time that the foundation is laid for the premium quality of Iberico products. Without a successful Montanera, the production of Bellota-certified hams would be severely limited, impacting not just the market but also the centuries-old practices that define this industry.
The care and attention given to the pigs during this season reflect a commitment to maintaining the highest standards of quality. For those who savor Ibérico Bellota ham, the Montanera is a testament to the meticulous process behind every slice of this iconic delicacy.
