In some regions of Germany, beer wasn’t traditionally as common as you might expect. By watering down wine, you get a beverage with a similar alcohol content like beer which you can drink in similar contexts - for example, it’s not a great idea to drink undiluted wine when you’re sitting outside on a hot summer day

Why do you do it? To have a less strong beverage?
As far as I know, yes.
