We were already in Fairfield to visit family so we decided to take a factory tour at Jelly Belly Factory. The tour isn't as nice as it used to be. There's no more host, just a self-guided tour. But it's still fun and worth it if you are already in the area. You can be in and out of there in about an hour unless you stop in the cafe for lunch.
During the tour you can see views of almost the entire building and see videos of the candy making process. You can also admire all of the art created with jelly beans. The tour ends at the factory store, which has thousands of flavors of jelly beans, including a new intentionally gross and disgusting category. There's also unique types of fudge and other candy. And, of course, there is a lot of merchandising (shirts, hats, toys, underwear).
