Monique and Jim and I compared "new world" and "old world" wines the other day at a local tasting chez nous. The new world Chilean Gran Reserva Shiraz from the Colchagua Valley (2005) by Louis Felipe Edwards came out much better than the very good St. Emilion (don't have the details of the bottle since I recycled it but have another bottle of the Chilean)
This was proved very dramatically in this account of a wine tasting that was in the Telegraph today. New world wines of $30-$40 stacked up well against old world wines of $600-$2,000 a bottle.
