Napa Winery Suggestions

i'm planning a day trip to Napa in early October and i wanted to reach out to some of the wine connoisseurs out there.

i'm looking for wineries to visit and tour. since it's our first time visiting, we'd like to visit the top 3-4 wineries for the scenery and beautiful surroundings.

As of right now, i know we definitely want to visit Opus One and Sterling.

Any other suggestions?

Thanks in advance!
