For Batch 5, we've gone Greek, to that chunk of land west of Athens. The land of Spartans, olives and honey: the Pelopennese!

I visited for one sweaty week last July and met Pavlos, a farmer with an olive grove in the village of Parapougki - bang in the middle of the peninsular. His grove sits on a shrubby hillside with views over seemingly endless shrubby hillsides dotted with olive trees. There's a reassuring feeling that the olive tree is very much at home here.

His trees all grow the famous Koroneiki olive variety. It's the native olive to this region, which has become the most common olive variety in Greece. An olive small in size, but with a surprisingly high oil yield (often up to a third of the olives' weight is oil) and low acidity.
