Pure joy of life
For many a cold beer is as essential for a perfect sunny day as barbecuing, swimming, the faint sound of a western guitar - or, not least, a vist to a cozy beergarden. However - not long ago enjoying a glass of the golden ›barley juice‹ wasn't a naturalness at all between the month of June and September.
Until the late 19th century mostly bottom-fermented beer (like ›Helles‹ or ›Pilsener‹) was served in Germany - and that type of beer needs relatively cool temperatures during fermentation and storing. For that reason before technical cooling methods were established bottom-fermented beer had to be brewed almost necessarily during the colder seasons. For the longest time the only possibility to store the delicate product during spring and summer remained deep (and therefore cold) beer cellars.
This conservation method was probably first introduced in the city of Munich, deep in the river terraces of the Isar, fed with the cool waters from the Alpine foothills. In order to further lower the temperatures the grounds around these early beer cellars were covered with gravel and chestnut trees were planted to provide shade. Some of these original cellars survived to this day, as in the city districts of Haidhausen and Schwanthaler Höhe.
In order to maintain the cold chain the cellar breweries were eventually permitted to serve their products during the summer right on the spot. For that, simple benches and tables were set up under the chestnut trees - and hence the beer garden was born, much to the delight of the Bavarian capitals citizens.
