The Santa Clara Valley is home to over twenty wineries, and the Guglielmo Winery in Morgan Hill is a lovely place to spend an afternoon. Some wineries are nice for a quick taste, and others are good for a longer visit. Guglielmo is the latter.
It is just north of Gilroy and a short distance from the 101. The grounds are beautiful, and there is plenty of free parking.
They have managed to keep the family atmosphere, even though it is a larger winery. After chatting with a friendly employee, I asked if she was a family member. She wasn't, but feels as if she is, since she loves her job so much.
I'm pretty sure that everyone I came in contact with also enjoys is just as happy with their job.
