The Tragedy of a Nice Beer Foam Head

Beer foam has a short existence. It is born, lives, and dies.

by Peter Keusch

This is a must read article / experiment about two Weizen glasses filled with beer and the inner surface of the top of the first glass is covered with fat. The weizen beer is poured gently down the side of the glasses tilted diagonally until a perfect head is created millimeters from the rim.

Note: The fat represents the usage of fatty based soaps to clean glasses and the residue that is left behind.

Results:

The foam head in the first glass is smaller than in the second glass. It collapses rapidly.
