The Tanche, probably the best known French olive cultivar,[1] is grown primarily in the Drôme and Vaucluse regions of southern France.

[3] It is a cultivar of medium vigour, with a spreading growth form, elliptic leaves, an expansive global crown, and large size.

[4] The fruits can be harvested at smaller size in late November, while for larger olives it is better to wait until December or January.

[5] The oil has a "smooth taste and an aroma of crisp green apples and freshly cut grass".

Tanche is vulnerable to certain pests, in particular Spilocaea oleaginea, Verticillium dahliae and Bactrocera oleae.
