Its a dry stout, you can tell by several methods, first, in that it contains no crystal malts, nor other low fermentable sugars (lactose, maltodextrin, etc). Second, its mashed at a lower temperature; usually, but not always, drier stouts are mashed lower in order to make the beer thinner, more sessionable, and obviously, drier.
Third, look at the ratio of IBU's to original gravity. In this case it is 37% (17.2 / 46), which is in line for a dry stout, which normally ranges from 30-50%, sweet stouts tend to have a higher ratio (50-70%).
