(in the world) is in the north of the state, in the Franconian region. There, you can find a brewery in almost every village (it is sometimes very small and maintained among a few families). You can find a lot of local beer specialities, as for instance the "Bamberger Schlenkerla" (a beer with a taste of smoked bacon), so try to stick with the local beers always—-especially tasty (and supposedly healthy) are the unfiltered beers (only served in pubs).
In summer, you can generally find beer festivals everywhere - not only in the bigger cities, but also in the smaller villages; be warned though that the beer there is often served in one-liter ceramic or glas glasses called "Mass". The biggest certainly is the Munich Oktoberfest , followed twice a year by the Nuremberg Volksfest . Also very nice is the Erlangen Bergkirchweih .
Bavaria’s beer garden  season starts in May and runs right through to October. The shade of ancient horse chestnut trees become a rendezvous for both young and old and locals and visitors alike: a place to enjoy a convivial glass of cool beer and some tasty Bavarian snacks. You can even bring your own picnic.
Germans generally make brandy out of everything; most common are the fruit brandies (Obstler) and the herb liqueurs (e.g., Sechsämtertropen form northern bavaria). For a real Altbayerisch felling try Bärwurz, Kräuterwurz, or Blutwurz.
The north of Bavaria is famous not only for its beer, but also for its (white) wines that come in special bottles called "Bocksbeutel" (bottles with a big round yet flat belly). For a sweet treat try Eiswine, made from grapes allowed to stay until the first hard freeze then pressed and made into a very sweet wine.
Statistically, Bavaria is one of the safest regions (if not the safest) in Germany and probably Europe. The biggest threat to your wallet are the (perfectly legal) high prices.
Be aware that there is a big difference between the Bavarian police and the police from maybe Hamburg or Berlin. In Berlin, it might not be a problem if they find a few joints in your pocket (because you may carry it for your own needs). In Bavaria, it definitely is a big problem for you. Still, you won't have any problems if you drink alcohol in public as in all of Germany and Central Europe. Beer or wine is permitted if you are at least 16, spirits at least 18, but the law is loosely enforced.
