Bischoff Oktoberfest

I was offered at a bar what the barman called an Oktoberfest beer by Bischoff, it was a cloudy unfiltered lager. I have not found any oktoberfest offering from bischoff so I thought it might be Christian Bischoff Kellerbier.
Any thoughts on the matter...

I’d say that is the one - that is the only beer that they brew (besides the Weizens) that would be cloudy. Nothing about an Oktoberfestbier on their website (anyway, very few Rheinland-Pfalz breweries even brew a Maerzen style).

Thanks, that is probably it.
