For the well-heeled epicurean, a destination that is a must see is Tuscany. There’s a mystique and legend around it built over water coolers in faraway places as those who return regale stories of rolling hills of grape, golden sunsets over wide open fields, rustic estates dotting the landscape and, of course, the wine. The fantasy of Tuscany builds beyond that with dreams of staying in the luxurious accommodations in a grand estate and having an exquisite gourmet dinner under the stars with your loved one. It will invariably include swirling, sniffing and tasting wines, in their own terroir, that you’ve had at the top restaurants in New York or perhaps in London or Hong Kong.   This is what we dream of when we think of Tuscany and it just happens to describe what awaits the forlorn oenophile at the Castello Banfi-Il Borgo Winery Estate.
