Listermann is my home brew store. I live about 20 mins away. I've brewed an Amber Ale, Gomez Lager, and Dunkel. The Amber and Gomez are excellent, and although the Dunkel was highly recommended by Will and Alan (great guys who work there) I was not impressed. It had a strong caramel-like after taste that I really didn't care for.
I have another Amber in primary right now and am looking forward to kegging it!
FYI, I've also bought IPA kits from Northern Brewer, and while they are more 'big league' from a shipping/organization perspective, I prefer Listermann.
