As the name suggests Orange Muscat wines have a strong aroma of oranges. In some wines this is quite overpowering, and it gives the impression that the wine will be sweet. This is not always the case. Some Orange Muscats are quite dry, just as some aromatic Gewurztraminers are quite dry.
The variety seems to lack the lushness of other muscats so this part of the name is a distraction.
Orange Muscat is belived to have originated in France or Italy but it is seems it used now only in Australia and in small acreages in California.
Off dry or sweeter Orange Muscat wines would go well with soft cheese, cream based desserts or even this Bread and Butter Pudding recipe.
