I'm behind but I HAVE THOUGHTS!
Mulled wine does NOT contain butter. No, no, no. I come from the land of mulled wine and no one, and I mean NO ONE puts butter in it. However, there is a lovely alcohol free version called 'Kinderpunsch'. It's apple or cherry juice (of half and half) heated up in a big saucepan with mulling spices (clove, cinnamon, maybe ginger, star anise or vanilla, too) and orange slices. Served with a ladle into mugs, it's the loveliest drink for daytime Christmas market visits.
Now, with regards to creating the flavour profile of brandy through the medium of sorrel, here's a snippet from

Flavor profile of sorrel
Given the origin of its name, it should not be surprising that sorrel is most notable for being sour. It has a strong acidic note that is the result of its oxalic acid content. Its intense acidity allows it to be used in salads in lieu of vinegar and is thought to make it ideal for pairing with eggs.
And the blurb from a bottle of Hennessy (other brands are available)
Candied orange, cherry and dark chocolate notes mingle with the vanilla and peppery spice of the casks, which are present in the long, warm finish.
Saved for years and years to buy my first house at the age of 40. Didn’t once go without butter during that time.
Was I doing it wrong?
You could have had your own house aged 15, had you only stuck to lard and squirty cream.
