Is the fome of beer alcaholic?

The answer is no, the foam of beer is not alcoholic.

Here's why:

* Foam is mostly air. Beer foam is created by bubbles of carbon dioxide gas trapped in the beer.

* Alcohol stays in the liquid. The alcohol in beer is dissolved in the liquid, not the foam.

So, while the foam of beer can contribute to the overall flavor and experience, it doesn't contain any significant amount of alcohol.
