I sometimes get questions from customers who are frustrated because their beer layering attempts fail when the top layer immediately mixes into the bottom beer layer. As we say in our Instructions page, when this happens, reversing the layers oftens result in good layering.
I did a little research about what actually happens when a denser (heavier) top liquid drops into a less dense bottom layer. This behavior is due to a fluid mechanics phenomenon known as the Rayleigh-Taylor Instability.
Below is a video showing Shiner Black Lager mixing quickly with Hoegaarden Wit. I tried reversing the layers as well but the Wit didn't layer over the Black lager either.
We would love to post your pictures in this blog. Send them to email@example.com
