The dark clouds of beer monopoly are on the horizon and will reach four Swiss cities in a few weeks, therefor I think it is time to update this thread and post some new information and experiences!
I have some good news, Bier Paul must have had some success in the last year. I encounter it more often in the city and had occasions to taste most of their brews.
bier paul 01 - their Lager-y beer from barley and hop. I like it.
bier paul 02 - unfiltered black beer made with two malts. I don't like the slightly bitter taste.
bier paul 04 - the summer edition. Barley and a bit wheat. Between Lager and white beer in taste, top.
bier paul 06 - a Stout that they brew in spring. Bitter and only slighty sweet. The second one is better than the first. Oh and the third one better than the second.
Check the
Erusbacher website for bars and shops that sell bier paul in the canton. There's a Rampenverkauf in Zurich Wiedikon.
Also I haven't recommended
Barbara from Eichhof. (This last big independent brewery was recently bought.) I don't know how to describe it but I even think it's a good first step for those who only like Lager so far!
