Located at 4,500 meters above sea level and virtually untouched by humans, it would be hard to find more pristine water than our water source, the Ccelhuaccocha (hel-uwah-ho-cha) Lagoon. Formed from glacial meltwater, the runoff from this aquamarine lagoon travels through 7 kilometers of canals before reaching our vineyards.


These canals were built as part of a special project called The MERRIS Plan, a joint collaboration between Peru and Germany that initiated in 1975. Designed to promote sustainable and competitive agriculture in the Andes and Amazon Rainforest, hundreds of small-scale farmers in rural Peru have received access to water to irrigate their crops.


Along with 180 members in the Curahuasi Valley, we are part of a water cooperative, small farms reaping the benefits of this canal system that connects us to Ccelhuaccocha. For now, there is more than enough water for everyone. In fact, 55 liters of water per second flow through the canals to reach the Curahuasi valley. That’s an incredible 1.7 million cubic meters of water available for dispersion every year. Whatever isn't used flows to the Atlantic Ocean via 3 rivers: the Lucmos, the Apurímac and the mighty Amazon.


However, despite this resource’s plenitude, we use water sparingly at Apu. Only when the hillsides of the Curahuasi Valley start to parch during dry season (April- October) do we tap into the irrigation system. Our focus is on conservation- 2 hours of watering by drip irrigation per week is enough to sustain our grapes.


Preservation of this precious resource is necessary. Peru’s glaciers are at risk of disappearing because of global warming. As noted in Peru Climate Change: Impact on Glacial Melt & Access to Water, people in rural areas, especially small-scale farmers, will suffer the most when the glaciers melt. Apparently the destruction is imminent. The report states: “glaciers in Peru have irretrievably lost one third of their surface area since 1970. The now unavoidable melting of glaciers in Peru will severely reduce water supplies in a country that is already water poor”.


This alarming fact has compelled us to take more steps to conserve water. First, we are exploring dry farming at Apu. We think our soils would facilitate this method; limestone allows the vines to grow deep roots to access the rainwater stored in the earth, even during the driest months. Second, as president of the watering cooperative, Fernando is teaching conservation to the other members. As a result, people have started replacing surface irrigation with tanks, tubes and drips. Third, Fernando is also working with engineers from the Ancapara Program, which was designed by the Regional Government of Apurimac to improve infrastructure of irrigation systems. They are currently installing pipes and sprinklers across the Curahuasi Valley and teaching people how to use them.


Water is essential for winemaking. Approximately 85% of every bottle of wine is water. In the case of our premium Peruvian wine, 85% of every bottle contains a mix of glacial meltwater and Andean rain. However, the necessity to conserve water drastically transcends winemaking; lives depend on this precious resource. We will do our part to protect it here at our high-altitude winery & vineyards, both through conservation and education. In the end, we hope our small efforts will have a much greater impact on the Andean and worldwide community.

Part of the adventure of this ambitious project in the Andes has been living completely “off-grid”, which required us to change our mentality about energy and resource consumption. Although it was difficult to adjust our lifestyle, reducing our carbon footprint and promoting sustainability in winemaking has been surprisingly gratifying. Here are some examples of how we operate sustainably here at Apu:


Electricity- Manual labor replaces the work of machinery such as crushers and destemmers. With the assistance of the steep slopes at our location, we have a gravity-flow system, which efficiently channels water to our home, winery, and vineyards, eliminating the need for pumps. Furthermore, we have 4 solar panels that convert the sun's rays into 12-volt electricity, which transfers to 3 batteries. A transformer then converts the energy, supplying 220-volt electricity for all our needs.


Refrigeration- 2 solar panels provide electricity to our small refrigerator and freezer. This is sufficient to keep our food safe for consumption. We will soon be investing in a larger solar freezer so we have chillers onsite to assist with cooling during fermentation.


Water- The water that supplies our vineyard, winery and home comes from: runoff from the Andes, high-altitude Andean lagoons, and rainwater. We use rain gutters and tanks to collect precipitation and cement and fiberglass tanks to collect runoff. A system of tubes, valves and drips form part of our gravity-flow irrigation system, which functions when the runoff gains velocity as it descends down the mountainside, creating the necessary pressure to expel the water from the tubes and drips. Finally, to make potable water, we use a system of carbon filtering, solar rays, and a ceramic cask filter system.


No-waste winery model- At Apu, we reuse all organic material from our home and winery. Food waste goes to compost and stems, seeds, and grapeskins are used to make pomace brandy (and then composted). All of our organic material is used as fertilizer in the vineyard.


Organic when possible- We avoid harmful chemicals whenever possible. This especially applies to our weeding technqiues. Since we can't weed mechanically and we don't use herbicides, we remove unwanted plants and brush completely by hand. In addition, here at Apu we have created an organic anti-fungus concoction of lime sulfur, copper sulfate and sulfur to control mold and mildew during the rainy season. So, instead of spraying with fungicides, we paint our recently pruned plants with this concoction, as seen in this photo:




Architecture- Part of our house is built underground, which provides a natural air conditioning system when days are scorching. These cool zones act as cold storage for wine bottles. They are also helpful when we need to slow fermentation or stabilize tartaric acid. Finally, the construction of the house was completed with recycled materials and plaster, eucalyptus and stones from the area.


It makes us proud to make delicious wine while supporting sustainable practices. We hope our model continues to work in the future as our vineyards expand and our needs for energy grow. In the meantime, we will be cognizant to technological advances that will allow us to operate even more efficiently in our off-the-grid home and winery.
