The link below leads you to a site where a group of people created a new type of sriracha by putting the sriracha in a whiskey barrel. the Sriracha can be aged for one to three months. This new type of sriracha is said to have a smoky flavor to it.

Barrel aging can be found in many products and the shared use helps build complexity. I also like that this is a cool new start-up. So cool.
