Peel 2 of the oranges and dry the peel either above a radiator or in a very cool oven. Squeeze out the juice and reserve.
Roughly chop the other 2 oranges and put these along with the dried peel and all the juice into a large wide mouthed jar.
Add the rose wine and pop on a lid. Set aside in a cool cupboard for 3 weeks.
Strain out the solids, pour back into the jar and add the sugar, vodka and brandy.
Pop the lid back on and shake the jar every day for a week to dissolve the sugar.
Strain through muslin into a jug and pour into a pretty bottle or decanter.
Serve this orangy delight ice cold and imagine French sunshine in the middle of winter.
