The main flavor is cocoa (not “chocolate” but if you’ve ever tasted unsweetened cocoa powder it tastes like that). The other spices emerge after longer steeping. It’s not what I typically think of as “chai” (which is heavy on the cinnamon and cardamom), but it’s “chai-like”.
If you’re looking for something more chocolatey, try this instead: http://steepster.com/chai-mera/posts/299406
