You have the flair for the linguistics (see label lore). From another point of view, imagine a sheep on its back that can't get up
As my clan is from Yorkshire, (I grew old in Canada) I thought I would post the whole damn thing.

BLACK SHEEP RIGGWELTER YORKSHIRE ALE
Brewed in Masham, Yorkshire, England
Riggwelter's coffee flavor hits the roof of the mouth with a bitter zap and remains there. Hints of chocolate firm up the mouthfeel as the well-calibrated bitterness stays the course. Its dark, red-brown body actively supports a craggy tan head. A malty aspect weaves in and out, softening the bitter quality a bit. The coffee presence returns at the end in a more subdued guise. This is a sturdy, very likable ale.
LABEL LORE
Riggwelter is derived from the old Norse words rygg ("back")
