Which of the following beers has a higher OG than 1.055?

Belgian Dark Strong ales typically have a higher original gravity (OG) than 1.055, often ranging from 1.075 to 1.100 or even higher. These beers are characterized by deep, complex flavors that come from the rich malt backbone and the fermentation process involving special Belgian yeast strains. Their higher OG is attributed to the inclusion of caramel malts, candi sugars, and sometimes dark malts, which contribute to both the density of sugars and the resulting flavor profile.

In contrast, Kentucky Common, Sahti, and Pivo Grodziskie are generally lower in OG. Kentucky Common, a historic beer style, typically has an OG around 1.050 to 1.055. Sahti, a traditional Finnish farmhouse ale, usually has an OG similar to that range as well, often landing between 1.040 and 1.060. Pivo Grodziskie, a lightly smoked wheat beer from Poland, also tends to have a relatively low OG, often around 1.045 to 1.050.

The higher OG of Belgian Dark Strong ales is essential for creating the style's characteristic richness and intensity, making it the correct answer in this context.
