Though there aren’t many rules, keep some guidelines in mind when you’re picking what kind of chocolate to gorge on while polishing off your favorite bottle. For example, since both wine and chocolate contain flavanols, or antioxidants, you want to watch them in each -- high levels in both the wine and chocolate will clash on your tongue and make the wine start to taste more bitter.
As a baseline, you probably want to be drinking something sweeter than the chocolate. Kind of counterintuitive, but this is one case where you want the wine to play understudy.
When it comes to full- versus light-bodied wines, match it as best you can to the chocolate you’re eating. A rich chocolate wants a full-bodied wine; a lighter chocolate wants lighter bodies, like a bottle of white.
Also pay attention to the finish you’re going for; if your wine leaves a crisp taste on the tongue, leave silky chocolates behind.
