I have lived near Napa and visited many a vineyard around the world.. This one was right near the bottom of my experiences. Sorry guys. I'll give them a little credit because we showed up at 3 on a Sunday.. But...
First they only had merlot and chardonnay to offer in their flights. I'll also admit merlot is my least favorite wine, but even those were flat and disappointing. Only the first chardonnay had any appeal to it.
They didn't have any thing to offer us between the tastings so I couldn't get the taste of the last wine out before trying the next. Plus they poured the wines into our glasses, one right after the other, not even rinsing them. Our flight was supposed to come with cheese and crackers, but they didn't have any cheese to offer, nor did we get offered anything we paid for until we had the flights completed. The tastings occurred along a short bar area on one wall, so we felt crowded with the other patrons. Between the crowded feeling and less than desirable wines we skipped two tastings. Since they didn't have any cheese, we got a plate of soprosetta and a plate with hummus. The hummus showed up still in the plastic tub you can get at any grocery store. Both were served with bland Carrs crackers..Even though we had a local acting like a wise old sommelier telling us about the "finish"... they failed.
Only thing I found appealing about the visit was the outside patio and the singer.
