The vines at Trella are grafted onto disease-resistant rootstock and planted in a mix of Oakland-Nonpareil-Sutherlin soils and Abegg gravelly sandy loam. The area receives an average of 41-43 inches of rain per year with summer temperatures in the low 80s and 2200 growing degree-days. Trella Vineyards operates under the credo that choices made in the vineyard have an effect not only on the wines but on the health of the environment in the future. Sustainable farming practices are employed to bring the vineyard into harmony with the environment, rather than into competition with it. Utilizing natural cover crops to minimize erosion, drip irrigation to reduce water waste, and establishing habitats for natural predators such as owls and bats all contribute to a thriving ecosystem that leads to balance in the vineyard.
