The Hadernder Bräu is one of the smallest breweries in Munich. The history of the brewery is not very long. They started brewing organic quality beer around 2016. They now have four types of beer and new or seasonal beers are added all the time.
Although the beers are available in some shops in Munich, it is still worthwhile to travel to the brewery, even if it is located a little bit outside of the center of the city. You have the possibility to taste and buy the beers directly in the brewery. The great thing about it is that you can visit the brewery, and the owners are there to show you around. Martha and Thomas like to talk about the beers and the small history of the brewery.
I must confess, my favorite is the IPA, and where else do you get an Indie Pale Ale in organic quality? In addition, they also make a pale, a wheat beer and a dark beer.
My suggestion is to get a bicycle or a car and drive to the brewery, in case you want to buy more beers to take away.
