My favorite beer style is Octoberfest/Marzen. I love a malty brew with some bitterness. Having said that, I'm not yet equipped to brew lagers. But I'd still love to brew something of similar taste in an ale. Will an Alt do this for me? Commercial examples are non-existent in my neck of the woods so I can't really find out for myself.
Can anyone offer some insight and/or recipe advice?
Typically an altbier would be darker and hoppier than a Marzen. If you prefer the Marzen style just brew a recipe as an ale, using a clean ale yeast and temperatures at the low end of the yeast's range. There are hundreds of posts on this topic here and on all of the other homebrewing forums.
