I know it's not a tobacco, but i'd recommend trying the cappuccino jubilee from VF. Jason was kind enough to toss me a bottle with my last order. It's got a very distinct coffee flavor, without being overwhelming or sweet, as too many coffee juices seem to be. I've been enjoying it on its own, but I've also found that 4 or 5 drops mixed with a couple ml of tobacco juice adds a really nice dark complexity. I've tried it with a handful of tobacco liquids, and so far it's worked great with all of them.
