Start off at SamuelAdams.com, they have some decent information on all their beers. If you don't feel like looking, here's what I pulled down.
"Brewed using only American 2-row malted barley and German noble hops - Spaltner."
"Color: Golden to Light Amber"
"Grain: 2-Row, Crystal 60L"
"Starting Gravity: 9' Plato"
"Hop Varieties: Spalt-Spaltner"
"Yeast Strain: Bottom feeding Lager yeast"
That should be a pretty good start. You can probably formulate a pretty close "clone" since the ingredient list is so short. Only 2 grains, only 1 hop, and they give you the starting gravity and final ABV. The only key piece I see missing is an IBU amount, but you may find that with some looking around or judge it by doing a taste test. I'm guessing its semi-low - not as low as Bud Light, but not American Pale Ale high either...
You will need the ability to lager in order to reproduce this though. Being such a light beer, any fruitiness/esteriness from using an ale yeast and higher ferment temps would be pretty evident. Not saying it wouldn't still make a decent beer, but it won't be a clone without being lagered.
Hope this helps.
