Fair enough, and I will defer to your superior knowledge.

I'm still new enough at this that I'm still getting the nomenclature down, and that was the best adjective that came to mind.
I've never had any cream ales, so I was mostly working from the "stout" portion of the name. Guinness--and the few other stouts I've had--have some different texture that this stuff lacks; I think there might be a greater quantity of hops in the Sam Adams. In that case I don't get the addition of "cream" since it doesn't seem to have anything in common with cream ... but like I said, still working on the analysis skills.
Right now I'm on the last new flavor:
"Samuel Adams® Old Fezziwig® Ale is the Christmas cookie of beer. Bursting with spices of the season and a remarkably full body, it helps those long winter nights pass much quicker. The full body hits the palate first with a depth of malt character ranging from sweeter toffee and caramel notes to the more dark, roasty chocolate notes. Then come the spices in full force. Cinnamon, ginger and orange peel dance on the tongue bringing with them the celebratory spirit that goes hand in hand with the season."Overall verdict: the Holiday Porter and Cream Stout were the best, Cranberry Lambic least favorite, and Winter Lager and Old Fezzi somewhere in the middle.
