Pretty sure it's an English Yeast fermented fairly cold....probably Marris Otter base...not too much else just fermented real well...the BA version is even better...Zein is a mad genius
A well done barleywine done in the style I like. Definitely a decent amount of caramel malts in there. A little thin for my taste so I'd say to mash under 153 and probably under 150.
