IELTS Essay Task 1: Olive Oil
The diagram details the process of producing olive oil.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The diagram delineates the process by which olive oil is made. The production can be divided into 3 main groups beginning with initial harvesting and treatment, followed by creation of the oil, and lastly storage for future use.
The process begins with the olives being harvested from trees and placed in a collection vat. The olives must then be de-leafed and cleaned with water before they are put into an olive mill to crush them into olive paste. The paste is then put through a malaxer set to a temperature not greater than 27 °C. After the malaxer, paste then enters a centrifugal press which creates virgin oils.
Subsequent to this, the virgin oils are then either separated (with waste water being discharged) or decanted, which filters out both solids and water. Regardless of the method of separation, both products are reserved in a storage tank to finish the steps detailed in the diagram.
Analysis
1. The diagram delineates the process by which olive oil is made. 2. The production can be divided into 3 main groups beginning with initial harvesting and treatment, followed by creation of the oil, and lastly storage for future use.
- Paraphrase what the process shows.
- Write a clear overview summarising the major groups. Read here about overviews for processes.

- Begin writing about the details of the process.
- This one is tricky to get up to the word count (no longer required on IELTS) so try to make it a little wordy.
- Include every step in the process.
- Make sure you use good linking words.

Practice with the related process below and then check with my sample answer:

is byproducts here used correctly?
Yes, it is correct.
Doesn’t ‘byproduct’ mean unexpected product? but the olive oil here should be the major product
Hmmm, yes it does – I’ll update it to the primary product and the byproduct.
it should be” set not to greater than 27 °C” because the symbol indicating lower than 27 degree Celsius, not exceed.
btw, thank you for your great work.
Thanks for noticing that – updated!
