Had to google "Black lager" it sounds similar as it was very easy to drink.
Lee Byatt (owner of Byatts brewery) did explain the process of the porter, most went over my head! but mentioned that the some of the hops went in later.
Byatt's Novus (hopped porter).
Bloody lovely from the Byatt's Brewhouse bar, had a few tbf! On tap not the bottled type, tasted so fresh, good head, not bitter at all.
