Yes, we know you love chocolate, but like you found out on that one dinner date when you took the last swig out of the glass after the chocolate mousse dessert, it really does not pair well with wine. According to Winefolly, there is a scientific reason for this: when you bite into chocolate, it adds chocolate tannin, fattiness, sweetness and an earthiness to your palate. If you now take a sip of wine, it scrapes the fattiness and sweetness from your tongue and leaves only harsh tannins and sourness. So if you do want to pair, try a white chocolate, that has no chocolate tannins, or pair with a sweet dessert wine
