Wonderful, wonderful. I have been a Stag's Leap (watch the apostrophe!) fan for years. As a member of their wine club, we had the opportunity for a private tour and tasting. Greg was our host, and he was informative and hospitable.
In terms of history and significance, this is probably the most "important" winery in the Valley. It was their wine that first bested the French in competition in the 70's. There is a wall dedicated to those who have worked here, and many a famous winemaker has spent time here. Like most places we visited, the actual pressing operation was much smaller than imagined. This is made up for, though, in the quantity of barrels throughout the facility. There are some sights to see, and great stories to hear, such as how the founder sold the winery and does not allow any use of his name.
For a fan of these wines, the tasting was a rare treat. To have several glasses in front of you, each with a different one of their Cabernets allows you to compare. What is also interesting is that the wines are in general named after the vineyards or blocks from which they come.
A great morning. They are building a new visitor's center, I hope it does not change the character or "feel" of the place.
