I pass Domaine Chandon every day on my commute to Calistoga. I have tried to come and give it a shot TWICE now and have been completely ignored and/or rudely mistreated both times. Considering that Napa thrives on the "hospitality" industry, you will find no hospitality here. Just a bunch of bitter people working in an over-commercialized tourist trap / sorority party.
My first visit was about 5-6 months ago, and when we arrived to the tasting room we were promptly ignored for 20 minutes and then coldly told they were closing in 5 minutes so we wouldn't be served.
This week it was like deja vu. We showed up 15 minutes before closing time, came to the tasting bar about 10 minutes before closing, and -- you guessed -- were promptly ignored until 5:01 when the bitter older man behind the bar said "We're closed. Bye."
Okay. I get it. You don't want my business. And you don't want me to bring any of my guests or company VPs and business associates here when they visit and want me to take them out tasting. In other words, you're just so wealthy and wonderful that you must not need any extra business. Good! I won't provide you any. I have better things to do with my time and money.
Heck, going to the dentist is a more pleasant experience. This place has been the WORST experience I've ever had at any winery or tasting room in the world. And I've been to hundreds.
