There is a huge mistake here. The link states that Stag's Leap Wine Cellar 2011 Chardonnay won.
However, when you click on the link you show a bottle of Stags' Leap Winery. These are two different, unrelated and separately owned wineries.
Note the position of the apostrophe, before or after the s. The names were finalized in a California State Supreme Court ruling.
FYI. Stag's Leap Wine Cellar is the famous winery that won the 1976 Judgment of Paris with its 1973 SLV Cabernet Sauvignon.
So which winery won this contest, Stag's Leap Wine Cellar or Stags' Leap Winery?
