Concorde sparkling wine it was very cheap very sweet and nasty at the time just over £1 a bottle when it was first introduced, that was in Tesco in the 70's. I didn't know very much about wines at all back then it reminded me of drinking vinegar it puzzled me how wine experts could possibly detect hints of blackberry etc. to me it was like something to strip varnish with, so something as cheap as Concorde seemed like a good idea at the time. Blue Nun, Black Tower or Liebfraumilch were the next safe bet especially when trying to impress other 18 year olds. Now I prefer beer and fruit ciders.
