Kegged. Floral, some honey, and a strange sharpness to it, almost like a higher alcohol burn. Some cracker. The aroma is very subtle. Lots of honey in the flavor, and again, a sharpness in the flavor and finish. It's not pleasant at this point.

[7/10] Final pour. This has been a good, clean beer. Sudzers described it as "black tea" and suggested to not use Hallertau Blanc.
