Rudolph Valentino DiTommaso has thousands of growing vines to look after at his 20-acre estate vineyard and winery in Long Grove. Rudolph and his team harvest their fruits and age their wine in barrels made of French and American oak to yield more than 20 types of wines, all of which are produced completely on-site. And they take just as much delight in showing off their libations as they do in making them. The vineyard regularly hosts seminars and tastings, which guests can pair with tours of the vineyard.
