OK, the first question - where will I find Ginger Wine, an English favourite in the Garde, preferably somewhere near Nimes?
Have a look here,
They have it in the Best of British shops (www.bestofbritish.fr )
They are listed here : http://www.bestofbritish.fr/products8.htm
"Little Fat Narm" has a Brit-foods stall in Cuxac d'Aude (Friday) and Lagrasse (Saturday) - he can get just about abything you want in the quantities you want.
And what better reason can there be to visit the historic Lagrasse market in full swing?
