Combine juices and spices in saucepan and heat until just simmering. Hold temperature just below a simmer, steeping spices until juice is well flavored, about an hour. Strain out spices.
Add 1 bottle of red wine and bring temperature back to just below a simmer.
Add brandy as desired to individual serving glasses, then top with mulled wine.
Notes
Leftover wine may be refrigerated, covered, for a couple days and reheated as needed.
