I'm a big fan of Ampthill Brewhouse's session ale, which is described on Ratebeer as having, among other things, a raw grain flavour. It's a taste I've only encountered in the first home brew I made on a course (don't know what grain it was), and also Late Knights' session beer. Some of the Badger ones are also similar. It's definitely grainy but also nutty, ginger and not overly malty. The ingredients are listed as malted barley, yeast and whole cone hops; it's not the hops giving this woody flavour is it?
