• Alpine Tea Co has a 5.4 KWA solar panel system that is a part of our Pump house.
  • Since we installed the system, we have been able to operate our irrigation system cost neutral.

  • We utilise Integrated Pest Management (IPM) fundamentals in production of our green tea.
  • We prefer to encourage the proliferation of nature’s warriors such as the lacewing insect, trichogramma wasp and ladybeetle nymphs.
  • Pesticides and fungicides are only applied during periods of infestation.
  • Did you know? The lacewing larvae can consume 60 aphids in an hour. The Native green lacewing is really effective in controlling the twospotted mite.

  • Green Tea requires regular irrigation during the summer months.
  • Once the soil tension reaches 25 KPA, the tea is watered to bring back to a suitable level.
  • The tea is irrigated at a rate of 5mm/hour.
  • Did you know? Alpine Tea Co developed a pop-up irrigation system for use in Green Tea. This was implemented across the Australian Green Tea Industry.
  • The delivery system is particular it must be high enough to ensure adequate coverage for frost protection (1600mm) and be able to retract to 800mm to not obscure harvesting.

  • Once the spring growth commences, early spring frost can be devastating to our harvest.
  • Our plantation is protected from frosts through our irrigation system.
  • Sensors within the plantation will automatically turn on the irrigation system once the ambient temperature and wind factor reach at certain level.
  • Irrigating the crop prevents the temperature of the leaf dropping below 0oC and stops damage from freezing.
  • Irrigation after a heavy frost – The water is frozen on the outside with no damage to the plant!
  • Did you know? Frost is also our friend. Green Tea requires frost during winter in order to create a staggered growth that provide the unique flavour of our tea.

  • Green Tea is a variety of Camellia that is grown in hedge rows.
  • The hedge is constantly trimmed is a process known as skiffing.
  • Skiffing occurs before, during and after the harvest session.
  • During skiffing the offcuts remain on the ground to provide nutrients for future crops.
  • The hedge is shaped to encourage a surface areas which provides space for maximum fresh leaf growth.

  • At Alpine Tea Co. we tailor our fertilisation program to ensure that our teas receives the right nutrient/s at the right time in the growth cycle to achieve optimum plant health and tea quality.
  • Plant health is monitored through regular analysis of plant tissue and the fertiliser program is changed to reflect the results.
  • As well as tending the nutritional requirements of the plant we also pay special attention to soil health.
  • The use of soil “Activators” encourage increased activity of beneficial microbes and fungi. These microbes and fungi work together with the tea’s root system to increase the availability and take-up of the nutrients that the tea requires.
ensuring our tea receives the right nutrients
  • Harvest season lasts from October to March each year.
  • During this period, we normally harvest three times.
  • Each year we aim to harvest 25 tonnes of fresh leaf per hectare.
  • The tea is harvested with a mechanical harvester.
  • The harvested tea is kept within air-conditioned bins.
  • These bins ensure that the fresh leaf tea is kept at optimum conditions prior to processing.
harvesting green tea
  • Our fresh leaf is processed in Wangaratta.
  • The first step involves steaming to denature proteins and stop any degrading through enzymatic action.
  • The tea is then rolled and dried over a couple of hours, til our loose leaf tea is achieved.
  • This is a very technical process and has taken the processor many years to perfect (for the Australian climatic conditions)
