There are many beer styles that peek out only occasionally, wheatwine is certainly in that group but Firestone Walker is using it in their latest Vintage release from their Barrel Program. It is called Houses In Motion.
Here is the beer description, “After aging this wheatwine ale in whiskey barrels for 12 months, we incorporated whole roast coffee beans, cocoa nibs, and cinnamon spice to accentuate its core flavors.”
