I used it on a really robust american ale. It finished it out well, but was a very messy yeast. I had trub on the bottom and after 3 weeks I still had a bunch on the top too. I ended up with a ABV of about 8% and a really tasty brew. I do recommend a good starter though, I did not use one, and I think I could have gotten a drier finish if I had. I used Warrior hops and called it War Dog. My advice is to Cry Havoc and let slip the dogs of war!!
