If your flight from Munich Airport is not the 'greenest', Airbrau, the airport's beergarden professes a commintment to 'sustainable brewing' in their words "so you can enjoy our beers with a clear conscience: Airbräu is committed to sustainable brewing techniques and regional ingredients."
Rene Jacobsen is the master brewer.
His beers are unfiltered.
The theme for the place seems distinctly Bavarian.
