I complained in passing in another thread that French wine press recommendations disappear quickly from Foire aux Vins shelves but nevertheless I have picked up a decent selection of bottles in the 5-10€ range at Carrefour and Intermarché.
Here is a sample-
Touraine Gamay 1ère Vendange Marionnet
Palette (tiny appellation near Aix-en-Provence) Ch.Bonnaud (famous Ch.Simone cost 3x this)
Jura Chard Sarres - Rijckaert
Cahors Chapelle du Closs - Triguedina
Fleurie la Madone - Dom.la Madone
Morgon - Souchon
Savoie Chignin-Bergeron - Fils R.Quénard
St.Nic.Bourgueil Mélanie - Taluau
Bergerac Tour des Gendres Primo de Conti
Saumur-Champigny Terrages - R-N Legrand (a favourite domaine of mine)
C. Languedoc Montpeyroux C. Truffières - Aupilhac
Super U and Leclerc whose Foires have not yet opened also seem to have some interesting offers
. Best appears to be Auchan but there is no nearby branch
Some of these will surely be good enough for me to post a TN here in due course.
