As the early morning sun rises, I find myself at Casanel Vineyards in Loudoun County, Virginia. It's harvest time, and Norton grapes are being hand picked by a small crew at this 42 acre family owned vineyard and winery. One of the members of this crew is Katie DeSouza, head winemaker and vineyard manager at Casanel. As she hand picks grapes she tells me about the wine these grapes will be used to make, the world's first sparkling Norton, Red Spark.
