Interesting little 2+2 discovery...
When discussing the feasibility of a suggestion to add a jazbay vineyard to his Kynesgrove mod, and after reading the Eslaf Erol series, Arthmoor observed the name of the land that these graqes grow in according to the books: "The Aalto". Though not geographically where the book says it is (according to the book, it'd be in "North Central Skyrim", AKA the Pale hold), the environment description matches the Eastmarch volcanic tundra. He then noticed the similarity of "The Aalto" and "Alto Wine". Could alto wine be jazbay wine?
