You could try Dordogne or a bit south in Lot/Lot-et-Garonne in France.
Rioja for red wine
White Rioja can be superb - and an absolute bargain, since many think white Rioja must be inferior to the usual red.
Writing of wine bargains, sherry must be the world's most underestimated wine - which suits me fine.
I have sampled sherry in the bodegas of Jerez several times.
(I really hope that the emerging economies that are Brazil, China and India do not import sherry in the quantities that Thailand imported my beloved vintage port.)

10 day self drive wine tour, I once aimed at 5 days in and around Epernay but had to cut it short after 3, the French police don't take kindly to iratic drivers, I was so ragged with booze my nerves were shot to shit. I decided it was much safer to do Carrefour instead.
