They live in London and Dorset and Prince lists "lunch, wine, reading and horseracing" as her recreations in Who"s Who. In a blind tasting test conducted by the Dail Mail she was humiliated.
She repeatedly guessed that cheap wines were expensive, and vice versa, guessing, for example, that an £8.99 supermarket bottle cost £65, another £8.99 bottle cost £100 and an £11.99 supermarket bottle "must be the super-expensive" one costing £595.
The participants were told in advance that one bottle cost £595. Prince"s description of the £595 wine was, "porky, salty and disappointing" and she said that she "couldn"t swallow more than half a glass".
