So it dawned on me that I should have brought this up before. You guys who are in San Francisco for the makerfaire, if you have time, I would suggest going by Jelly Belly. They are in Fairfield and give tours of their factory and how the Jelly Belly is made. My in laws live there & I have been a couple times. My in laws go there a lot & for occasions for birthdays or Christmas they will buy Belly Flops. https://www.jellybelly.com/california-factory-tours
Additionally if memory serves me right there was brewery/bottling tour not far away either.
