We stopped here on our way to Napa. We had time to kill or we probably wouldn't have stopped but ended up really enjoying it. The tour take about 40 minutes and is free. It is automated with a guide walking you to each station where a short video is shown describing what you are seeing. There is a great deal of robotic manufacturing which is interesting to see and also the human intervention. We are 2 seniors who enjoyed it. There were also families with kids who were also fascinated. They also have a candy store which has Belly Flops ( beans which didn't pass quality control) which are sold at a discount as well as all the candies they make.
