Northern Brewer, hands-down. They have sooooo many different ones, and they tweak the recipes over time, and keep adding new ones. I brewed an NB kit or two every week for a yr and always felt like there were more I wanted to try than I had time to brew.
Primary: Wheat Graff, Blackberry Wine, Pomegranate Wine
On Deck: White Grape-Cherry Wine, Ciders
Friends don't let friends brew alone.
