Mayne&Oelsner Sustainable Agriculture (M&O) is a family business with three main divisions: Agriculture, Jams, and Naturaleza Wines.
At M&O, we grow subtropical fruits and vegetables in our greenhouses in Valencia, Spain. All of this is done sustainably, certified, environmentally friendly, and respectful of the environment. Our products are fresh, healthy, delicious, and very close to the city, achieving a low carbon footprint.
We also use them to make exquisite artisanal and sustainable jams using family recipes, allowing us to continue enjoying fruit even out of season. In the Naturaleza Wines division, you will find our certified organic wines “La Casa del Árbol” in their red blend versions and a white blend from three plots of Sauvignon Blanc.

OUR PROJECTS
Our specialty crops are grown in greenhouses where technology allows us to make efficient use of natural resources: with drip irrigation, organic fertilizers, and the invaluable assistance of beneficial species: pollinating insects, biological control, and our native plant islands. This allows us to achieve a permanent synergy.
