After the success of the Mini Siphon Mk I, followed by the surprising failures of the full scale Beer Siphon Mk III, several changes have been made to the design to make it less fragile, less leaky, and hopefully just work. But would it produce a Black and Tan, or just more heartbreak?
After the successful test of a miniature siphon for making layered shots, it was time to try a full sized siphon for making a Black and Tan. But will it work?
The Black and Tan (or Half and Half in some countries) is a fascinating beverage, and an excellent demonstration of density stratification in fluids. Recently we have started to explore the possibility of using 3D printing to create a device that can make a Black and Tan by displacing a less dense beer with a denser one using a siphon rather than the traditional method of carefully pouring the less dense beer on top of the denser beer.
