I'm guessing so since Wyeast lists it as a lager. But they also say that " n brewing, Saccharomyces cerevisiae is the Genus and Species that is of the most significance. Ale and lager yeasts are currently both classified as Saccharomyces cerevisiae but historically have been considered separate species with lager yeasts in the Saccharomyces uvarum (carlsbergensis) classification."
Going by how they list it, and the aroma and flavor of the beer it produced when fermented at 55°, I'm sticking with Lager.
