Trevi Olive Estate Quality Standards

Trevi Olive Estate’s attention to quality standards applies to all aspects of oil production, beginning with tree selection and maintenance and continuing throughout the production process.

  • GPS design layout for the grove ensures harmony between the trees and the high levels of mechanization being used
  • Four metres between the rows and two metres between the trees maintains a healthy environment for cropping
  • Raised mounds and monitored drip irrigation ensures perfect soil moisture and no water-logging
  • Class A recycled water is sourced from the Virginia Irrigation Scheme – a superior and sustainable water source compared to the local underground aquifer which is under stress
  • Trees trained to adapt to mechanical pruning, improving harvest efficiency and reducing cost per kilogram of fruit harvested
  • Annual testing of nutritional levels in the soil and foliar testing carried out as required ensures correct amounts of nutrients are used
  • Biological control of pests, in conjunction with researches, ensures on-going increases in sustainability
  • Weeds remain non-existent along the tree line due to strong competition from the healthy, Signore trees
  • Planting of a permanent pasture in the inter-row areas of Lucerne, provides organic matter that can be mown, conditioned and placed along the tree line to supply a rich source of nutrients that promote biological activity while also increasing soil carbon and organic matter.
  • A special mower has been built to allow mowing, conditioning and placing along the tree line in a one pass operation.
  • Fruit testing for oil content and polyphenols regularly undertaken at the University of New South Wales to determine the correct time to harvest
  • Harvest contractors use modified, over the row grape harvesters and can process 500 trees per hour with 95 per cent fruit removal
  • Site planning allows for night harvesting when required by temperatures and weather conditions
  • Fruit is processed locally at a temperature of 28C in the malaxer
  • Waste from the processing is used in the surrounding olive groves to improve soil carbon levels and microbial activity
  • Finished oil is stored in Stainless Steel bulk storage tanks
