Depending on the region, "I don't drink beer" can sound a bit snobbish (as in "I only drink wine and champaign"). Other than that I've never heard anything bad when I ordered Apfelschorle (apple juice + carbonated water mix). And I think "Alkoholfreies Weizen" would even be accepted among very beer-centred groups. One cultural difference between Germany and the states is, that drunk-driving is much more actively shunned so its more acceptable to not drink.
