Riedel Glasses in Athens

Last week I was lucky enough to be invited to a tasting by Georg Riedel.
I always knew that Riedel glasses were the absolute "Rolls Royce" of glasses for wine tasting, but I have never been to a "Master Class " on why  different shapes of glasses have been designed for different grape varieties.
It was an absolute revelation!!!!
How the shape of a glass can so influence your enjoyment of wine. For instance drink a Pinot Noir in a glass designed for Cabernet Sauvignon and it will taste acidic and have very little nose.
Drink the Pinot from the glass especially designed for this variety , and you get all the fruit on the nose and a wonderfully elegant wine to drink.
At the end of the evening we were all given the tasting glasses that we had been using, so full of enthusiasm we did an experiment the next evening.
We opened a bottle of Hatzidakis Mavrotragano 2007 ,this is a red wine literally translated as "Crispy Black" and tried it in a pinot glass and then a cabernet glass.
The difference in the taste and enjoyment was astounding.
In the cabernet glass it tasted very acidic with no fruit, but in the pinot noir glass it tasted balanced and full of fruit, truly wonderful.
