Kinglake Olive Grove has planted three Olive Varieties:
Manzanillo is one of Spain’s finest varieties. It is also the most widely planted variety in Australian groves and, due to its productivity and high quality fruit, the most widespread variety in the world. The variety has been well proven in groves and research stations in many Australian states.
The flesh-to-pit ratio is superb (8.2:1), its flesh is an excellent texture and it is considered a ‘free-stone’ olive as the seed is very easy to remove from the flesh. This attribute makes it highly sought after by the processors of pitted and stuffed olives. The fruit are apple-shaped, light green-coloured and spotted with tiny whitish dots. They mature to a black colour with a hint of purple and are a medium size at 4.8g.
The tree has a low, spreading habit and while it is similar to many olives in that it can grow up to ten metres tall, most Manzanillo trees stay at around five metres for ease of management and harvesting.
Correggiola is an excellent oil olive. The Fruit is small in size, ripens late in the season, and has a very high oil content. Correggiola produces regular heavy crops. Although the tree has medium to high vigour, the mature tree is generally low at about 8 metres. Correggiola is said to be the benchmark for olive oil in Italy.
Sevillano is a large fruit (8-12g) and has a flesh-to-pit ratio of 7.3:1.
The fruit is generally oval in shape and is primarily used for fruit and pickling, with the oil content being low. It is an ideal olive to stuff.
Sevillano is used solely as a table olive because of its size and the fact that it has very low oil yield. The fruit is large and is usually picked green. The variety is mostly grafted as it has a low rooting ability. It is considered tolerant of cold and peacock spot, but susceptible to drought.
Sevillano has an intermediate start to bearing and low productivity. Ripening is early and it is considered self-incompatible and so should be planted with cross-pollination. In California it is planted as a pollinator for Manzanillo.
