    Apu High Altitude Wine- From Vine to Wine

    Updated: May 22, 2021

    Take a photo journey with us to learn about how we make our premium Peruvian wine.




    Step 1: Harvest and Selection of Grapes




    Our grapes are hand-harvested and selected, to ensure to only the best fruit goes into our wine.









    Step 2: Destemming

    After selecting the best fruit, a portion of the stems are removed. This is necessary so the stalky, bitter flavors of the stems don't overpower the wine. The manual destemmer also lightly crushes the grapes.


    About 15% of our stems are thrown back into the juice during fermentation of our Sangiovese and Cabernet Sauvignon. We feel it adds some sophisticated aromas, flavors and tannins to our wine.


    We then do a prefermentation maceration to develop more aromas. After that, we add yeasts to activate fermentation.











    Step 3: Fermentation

    Red grapes ferment with their skins to give the wine more intensity and tannins. White grapes are allowed a light maceration with the skins to add richness to the wine, but then they are removed after 1 day. Because of the lower oxygen levels at our high-altitude, it takes a little longer to ferment here at Apu Winery.





    Step 4: Pressing

    It takes an average of 7-10 days to complete fermentation. For red wine, we press the grapes to remove the skins and seeds, collecting the wine in a well down below for aging.


    White grapes will have been pressed at this point in the process.














    Step 5: Aging

    The Sauvignon blanc wine is transferred to stainless steel tanks for aging. The red wines age in both stainless steel tanks and French oak barrels.








    Step 6: Bottling and Labeling

    Sauvignon blanc ages for a few months, while our Cabernet Sauvignon and Sangiovese age longer. When this process is complete, the flavors and aromas of the wines have melded and reached their peak quality.



    The wine is filtered, bottled and labeled and then sent to Cusco, where it is distributed locally or send to Lima via plane.

    Fercal Rootstock in Apu's Vineyards

    Updated: May 22, 2021

    Grape rootstocks provide resistance to diseases and pests, promote a more extensive root system and improve tolerance of calcareous soils (Perry and Sabbatini). Because of their indispensable influence on the future success of vines, we carefully select rootstocks that will best adapt to our vineyards.


    The great majority of the vines we imported from France were grafted with the Fercal rootstock. Genetic analysis showed this variety is a cross between Berlandieri Colombard #1 B and 31 Richter, as seen below:



    In addition to being one of the most adequate for limestone soils, the Fercal rootstock is also resistant to chlorosis, downy mildew and anthracnosis. It moderately protects against gallicolae phylloxera and has a very high tolerance to radicicolae phylloxera.


    We don't know of any availability of the Fercal rootstock in South America; the majority of grapevines with this graft are located in France. Planted over an estimated surface area of 30,000 hectares, vines with this graft are found in Champagne, Aquitaine, Charentes, Alsace, Midi-Pyrénées, Val de Loire, Provence-Alpes-Côte d’Azur, Languedoc-Roussillon and Rhône-Alpes (Barbe).


    We believe that with the Fercal variety, our new grapevines will thrive in our limestone soils. Selecting the best rootstocks, tending to each and every vine, hand picking the best grapes- all are part of the meticulous viticultural process at our winery.

    High-Altitude Tannat

    Updated: May 23, 2021




    Tannat has historically been associated with southwestern France and Uruguay, but we hope that in 5 years, this variety will be associated with high-altitude Peruvian wine. We recently planted Tannat vines from France in our vineyards at 2,850 meters above sea level.


    There is no precedent for growing this variety at such a height. In Madiran, France, the average altitude is 128 m. In Uruguay, most of Tannat's vineyards are grown on the coast, in the departments of Colonia, Maldonado, Carmelo, Canelones, Rivera and Montevideo.


    Tannat wine is typically acidic and astringent. Due to the cool nights at our high altitudes, we expect that acidity to be even more noticeable. Following the techniques currently used in the production of Tannat, we may blend ours or use micro-oxygenation to soften the tannins. We will also make a rosé, limiting contact with the skins during maceration to prevent the wines from being too tannic.


    A consultant from France recommended we plant Tannat here in the Andes because the vines are resistant to mold and fungi, a problem we face during the rainy season. The plants also adapt well to areas with extreme variations in daytime temperature, which is one of the defining characteristics of our terroir. Tannat is an adaptable plant that can grow in a variety of climatic conditions. We hope to produce a bold and delicious Tannat wine in 3 years. Stay tuned as our vines ripen!
