Kangaroo Island must be one of the few places in Australia where one can combine one's love of sailing with wine tasting. I've found 3 wineries which are located right on the coast, namely Bay of Shoals Wines (near Kingscote), Sunset Winery (Eastern Cove, 6 nautical miles from American River) and Chapman River Wines (Antechamber Bay). From the first two cellar doors you can admire your boat in the distance while tasting that Shiraz or Sauv Blanc

PS Does anyone know of other coastal wineries with anchorages within walking distance (not just on KI)?
