Hoevels was formerly called Hoevels Bitterbier, but they since changed the branding, so it's now Hoevels Original. But yeah, it's a lovely amber, malty bitter-like beer, and presumably lagered.
They do make a Zwickel, but it's only available in the brewpub in Dortmund I was there a couple of weeks ago[/url:164r6c1p].
