Really like this visual showing how Orange Wine is made I found on-line!
Orange Wine or Vino Naranja is produced in Huelva and Málaga in Andalucia, Spain with white wine macerated with orange peel. Vino Naranja del Condado de Huelva is an appellation of origin for aromatised sweet wines originating in Condado de Huelva, Spain. The system of production and aging of this wine is a white wine flavoured with macerated orange peel followed by a process of aging by the solera system. Orange Wine from Huelva is usually dark orange to brown in colour. The brown colour is a result of sun drying of the grapes prior to fermentation.
