I have to admit up front that I am not a huge fan of the Clos Pegase wines. I enjoy them, but they aren't among my favorites. That said, they have some good, solid wines (and taste, of course, is a personal thing).
There are, however, two reasons to visit Clos Pegase that have nothing at all to do with wine.
One is the art. The family has amassed quite a collection of sculpture and art over the years and much of it is on display and publicly accessible at the winery. They even offer free daily tours (11 AM and 2 PM). Not all of the family shares an appreciation for art...our innkeeper (see my review of The Inn of Imagination) explained how the "black sheep" of the family once painted the fingernail of a giant thumb statue bright red. They had to fly in an expert to clean the sculpture.
The sculpture garden alone is enough to warrant a trip to Clos Pegase. But, if that weren't enough, if you happen to be there on the third Saturday of the month, you are treated to a free (no reservation required) presentation on Bacchus. Bacchus, the impish imbibing spirit, is the true driving force behind Clos Pegase.
Jan Shrem, the owner, presents "Bacchus the Rascal, A Bacchanalian History Seen Through 4,000 Years of Art." The multi-media presentation is given (except in December and January) at 2pm in the Cave Theater.
Another unusual thing about Clos Pegase is that they allow anyone to picnic at the site, including bringing your own brown bag lunch. Many other wineries expressly forbid this (some will literally shoo you away).
