Aging Peruvian Pisco

In past posts we have discussed various steps of PiscoLogía’s production process, including harvest, fermentation and distillation. So, what else must happen before our pisco is bottled and exported? Like most spirits, pisco must rest before bottling. In fact, the regulations of the Denomination of Origin require that Peruvian pisco sit for at least 3 months in neutral casks so as to not alter its physical, chemical or organoleptic characteristics. This allows the flavors and aromas of pisco to evolve, improving the overall quality of the final product (Consejo).

 

At PiscoLogía, we prefer a maturation period of at least 6 months. If we are lucky, our pisco will sit for a couple of years before we bottle. We believe the longer it sits, the more time the flavors and aromas have to meld. Our master distiller and partner Nati explains the reasoning behind this long maturation period: “pisco aromas are extremely volatile. During the sitting stage, these aromas stabilize and blend with the liquid. The Peruvian Pisco Standard requires a resting period of at least three months, but we have our pisco sit at least 6 months to ensure the best quality product”.

 

When discussing volatility in the context of pisco production, it means that the desired aromas easily evaporate at normal temperatures. That means if a pisco isn’t properly cared for, it will lose all its aromatic qualities. A recently distilled Peruvian pisco should rest in sealed neutral casks in order to prevent evaporation and to allow the aromas to blend with the liquid.

 

In addition to melding aromas, the resting period enhances the flavor of pisco while fading out unwanted nuances caused by impurities. Because of its effect on the flavor and aroma, the resting phase of the production process is crucial in creating a balanced, high-quality craft pisco.

Brix levels have reached 23° and our grapes have ripened to perfection, thanks to the balmy Peruvian sun. The fruit has an acidity of 3.4PH because of the cooling effect of the evening Pacific Ocean breeze. It’s time for harvest.

Flor and Samuel, who help care for our grapes, gather their family members in preparation for harvest. With an expected high of 28°C/82° F and humidity of 69% in Azpitia today, it will be sultry. To avoid the heat, we start picking grapes at 5:00AM, when the average temperature is 20°C/68° F.

To maintain tradition, we harvest by hand. That allows us to hand-select each and every grape that goes into our pisco.

The grapes are then destemmed

and then crushed by foot, in order to extract the juice, but not crush the seeds that could add bitterness to the juice.

A secondary crush then extracts the juice that remains between the flesh and the skin of the grapes.

Nati throws some skins back into the juice, just to ensure Azpitia’s natural yeasts are present.

In 7 to 10 days, the yeasts work their magic, the juice ferments and the wine is ready for distillation.
