Way back then, on summer evenings in France, say in Avignon during the theater festival, it was common to have Sidi Brahim, an Algerian red wine, with an authentic couscous.
I never tasted any Moroccan wines though.
I spotted a red one at a local store a couple months ago but did not take the plunge since I knew nothing about it.
I was not aware that they produced whites as well like the Guerrouane 'Abou Nawas' Vin Gris (pictured below).
I learned from Tunisian restaurant Le Dromadaire (in Selestat, Bas Rhin) which carries it that it comes from nearby Fez where the Guerrouane appellation is.
This Vin Gris is 100% Cinsault if I got my facts straight and suggested as a great pairing for fish dishes and spicy offerings.
They also share that 'Abou Nawas' was the name of an 8th Century poet 'bacchique' (as in Bacchus I guess).
The poet Abou Nawas was born in Iran and died in Iraq according to Wikipedia.
The North Africa page of ewineplanet tells us that Meknes and Fez are home to "the biggest region,
producing good reds from high-altitude vineyards beneath the Atlas
Mountains. Appellations here include (besides) Guerrouane, Beni Sadden and Beni
Zerhoune. The wines can be rich and chewy."
I found my way to Morocco and its wines thanks to Corsican winemaker Domaine de Vaccelli who enjoyed it during a dinner at Chez Bebert (Porte Maillot) in Paris.
I used his photo as an illustration.
