While dining at an Italian restaurant in England during a business trip, some co-workers of mine drank some wine that they thoroughly enjoyed. When we questioned the restaurant owner as to the wine's name, he said it was Orvieto (sic) [It is spelled as it sounded as I have no idea as to the correct spelling!]. It was a white wine. Being a novice's novice, I have no idea what I am looking for. Does anyone know what I am after?? I would like to purchase for a gift. Can I get it in the US?? Please help!!!
