Combine all ingredients, except wine and liqueur, in a high speed blender and process until smooth. If you don't have a high speed blender, soak the cashews in the water for at least half an hour first, then add the remaining ingredients and blend until smooth.
Heat wine and liqueur in a medium sauce pan over medium heat, until boiling.
Add cashew cheese mixture and whisk constantly until thick and bubbly.
Transfer to a fondue pot, if desired.
Serve with crusty bread, pretzels, raw vegetables, apple slices, etc.
