Before olive oil reaches the table, its story begins in the fields. In Rancho Queimado, researchers followed the development of five olive varieties in the groves of Quinta do Vienzo. Published in August 2026 in the journal Agropecuária Catarinense, the study explores differences between the plants and their relationship with the local climate.
Watching the plants' own timing
The research team affiliated with UFSC analyzed Arbequina, Arbosana, Grappolo, Koroneiki, and Picual during the 2023/24 growing cycle. Ten plants of each variety were observed, with their reproductive stages monitored weekly.
The technical term for this monitoring is phenology: observing when a plant moves through stages such as bud development and flowering. The study linked these stages to temperature, rainfall, and humidity records from Epagri's station in Rancho.
Each variety has its own rhythm
Arbequina began developing buds in July. In the article's table, flowers began opening in September; these are different points in the cycle. Picual, in turn, needed less accumulated heat to complete flowering.
The results describe that particular growing season. The authors themselves emphasize the need for more years of monitoring to understand how the varieties adapt. The findings are therefore not a forecast for the 2026 bloom.
From curiosity to an experience in the grove
Knowing that the research took place here changes the way you see a local product: alongside flavor, there is observation, work, and curiosity about the land. At your next tasting, you might ask which varieties make up the oil and how the producer describes them. It is an approachable way to start noticing differences without having to master the technical vocabulary.
Quinta do Vienzo advertises visits to its olive grove and mill, along with tastings, on specific dates. Advance tickets are required, and the property states that it does not have a shop open to walk-in visitors. Check the official calendar to plan your visit.
