For some reason I really like researching/writing clone recipes.
The first place to look for info is the brewerys website, in this case it gives us a good sketch of the recipe. (although nothing too surprising)
10% ABV
two-row malts
chocolate malts
roasted barley
flaked oats
98 IBUs
You can then try to get more info using google, rate beer, emails to the brewery, and your own tests (measure the FG of the beer). You can then put it all together into a recipe. Im not one for re-brewing beers, but if you really want to dial in a clone it is going to take a couple tries and some side-by-side tasting. Good luck.
