Are concerts "rain or shine"? Thx

From the FAQ on the website: "All concerts are performed outside and held RAIN or SHINE. Please dress for the weather. There is no covered seating. General admission seating is on the lawn. Shade umbrellas are permitted only prior to the performance(s) and during intermission. Normal rain umbrellas will be permitted during inclement weather only and must be put down during weather breaks."

Yes

Yes there are. Though there are instances where the concert can be delayed or relocated to another part of the winery
