The following is from something I posted earlier this year; "Rioja is graded in 5 categories; Excellent, Very good, Good, satisfactory and (the lowest) 'Average'. The years 2010 and 2011 are classed as 'Excellent', and I am buying from a German supermarket (Aldi) a fantastic 2011 Tempranillo Rioja at just over £2.00 a bottle. Rioja 2006 is rated at the lowest, 'Average', and yet looking at the Waitrose price list they are offering a 2006 for £22.99p. How on earth can they justify this?"
