Visted Willow Creek on Saturday for a tasting. The tasting room can be found in back of the vineyard at the end of a curving dirt road. The building is very large (and very empty) with the tasting bar at the back. The server was a very nice, but she was a bit overwhelmed and had a difficult time handling the other two groups and my husband and myself (8 people total). Alot of workers were in and out - but it looked like they were getting ready to service a group going on a tour so there was no one to help her. We had our choice of 4 wines for $5 or $10 to taste all the wines. They gave us very small glasses for the tasting, but the pours were generous. Although our server was extremely nice and personable, she did not know much about the wines or the varietals and there were no descriptions on the tasting menu. None of the white wines were chilled and I was surpised to hear they opened Dec 15th - as they seemed too disorganized to have been opened every day for 3 months.
The wines were very young, and I felt a bit overpriced as there was nothing notable offered.
The "sangria" was more like a fruit punch or wine cooler and when asked - no one could tell us what was in it.
We did not take the tour - I guess if you are more interested in the process and are looking for something to do - that is the way to go.
