Before I start thinking about the name for the festival:

Will the tickets be economy class or business class? Which airline? Which is the nearest airport? How are connections from Munich (MUC)? ;-)

Now about that name:

As the festival is in February, it might be cold.

So what about

<yourtownname> Cold Beer Festival

or - if temperatures are usually below 0°C in your place in February

<yourtownname> Frozen Beer Festival
