Getting a wine served in PLASTIC cups is a rare experience at a winery in Napa. Could have certainly done without it.
But when we later saw that other parties were drinking from proper wine glasses, the experience turned very bitter.
I guess this is what everyday DISCRIMINATION looks like.
Unfortunately, previous attempts to receive an explanation from Beringer did not yield in a response.
Conclusion: THE EXPERIENCE COULD NOT HAVE BEEN WORSE.
