In Asda, or Asdas as we used to call it in Wales, just now, this utterly delicious glass of springtime will set you back £4.83. Weirdly, as Jamie Goode pointed out on his blog, in the same supermarket, on the same shelf, the 'standard' Montana Sauvignon Blanc will cost you twice as much. The 'standard' is nice enough, the 'reserve' is a notch up.
So get down to Asdas before this pricing weirdness gets sorted. Because if you like New Zealand Sauvignons, you should fill the boot and spend the summer chuckling.
