Tsafaras has been robbed twice, with thieves stealing more than a tonne of his olives in one incident last month.
Greek police confirmed to Reuters that there is a spike in thefts of olives and olive oil across the country this year.
Greece is the world's third-biggest producer of olive oil behind Italy and Spain, which have seen similar incidents.
The decline in output has doubled olive oil wholesale prices to 8-9 euros per litre, according to government officials.
Retail prices have reached up to 14 euros, making the crop an appealing target for thieves.
