American Amber was the kit that I’ve made so far that was unreal how good it was. Second one was the “California Common” kit, really good, might have been better than the reference Anchor Steam.
Bavarian Hefeweizen was incredible right out of the carboy with all of the yeast flavors, it has tamed down a little bit with aging but still a great wheat beer. I now understand why they say to drink the wheat beers when they are fresh, you get the apple, clove, and banana flavors big-time.
Caribou Slobber was good but took a long time to bottle condition, until then the flavors were all over the place.
The Dry Irish Stout had the same flavor as Guinness but a little more rounded. Some stout-loving friends rave about it. Very very true to the style.
Kolsch Kit so far has been very good but nothing that really made it memorable. People that usually drink the macrobrews really love it, has more flavor than the usual watery stuff they drink but not too much for them to try it.
I’ve got The Innkeeper in bottle conditioning/carbing right now and Dawson’s Multigrain Red in the carboy. After that is the St. Paul Porter which looks promising.
