Wash your orange (good to use organic) Peel it thinly. Slice the ginger. Crush your cardamom pods or open with your fingers.
Pour your wine in a pot together with the sugar and all the spices. Let the mixture simmer on low heat so the sugar melts.
Remove from heat and let the glögg stand for at least 2 hours so the flavors intensify.
Strain the drink. Reheat before serving and serve from small cups.
Notes
If you want a more fruity flavor, then add the orange juice as well. To make your glögg stronger in alcohol percents, add ½ cup of aquavit, brandy, cognac, rum, gin, vodka, or blended whisky (not smoky). To make alcohol-free glögg use alcohol-free wine.
