Gleaned from an e-mail from a distributor:
Duvel will have its Maryland launch of its draft-only Duvel Green at Max's Taphouse on Tuesday, June 30th. [I presume this is during/as the weekly Beer Social.]
Never heard of it? See these notes from Lew Bryson (along with some commentary on Belgian beer marketing) back in September:
Duvel Green is single-fermented and filtered, where Duvel is fermented twice (second time in the bottle, both using the same yeast, we were told), and it comes in at a reduced 6.8% ABV. It is, however, brewed with that same yeast, same Styrian Golding and Saaz hops, and the same pilsner malt as the original.
