Sam Adams Cream Stout

Brewed this a few months back and it came out tasty, but I tried the original at the weekend and it has way more cappuchino flavor to it. I made a few minor tweaks to the posted clone based on ingredient availability and I don't know if that's what did it. Any thoughts on what to try next?
