Touriga Franca, also known as Touriga Francesa, is one of the major grape varieties used to produce port wine.
Touriga Franca is lighter and more perfumed than Touriga Nacional, adding finesse to the wine.
Jancis Robinson, the wine critic, describes it as playing 'Cabernet Franc to Touriga Nacional's Cabernet Sauvignon'.
Not much is known about the origins, but it was probably a cross of Mourisco de Semente and Touriga Nacional, as it is quite similar to Touriga Nacional, needing harsh conditions to keep vigor down, as it gets on the steep arid slopes of the Douro.
It is usually trained low to the ground under one of the Royat systems. Yields are medium (1,5 kg/vine), often not as bad as Touriga Nacional.
