Casablanca was my first all day vape and I chose it because it mentioned cocoa. There is cocoa in most cigs including Marlboro, Parliament, Capri, Pall mall, etc.
If you want to try a full-on Turkish Blend try FreedomSmokeUSA Desert Ship - nutty, a bit pungent, stronger than Casablanca and people including me say it reminds them of the smell of a freshly opened pack. While you are there get FSUSA Chocolate and Cocoa because they are great for adding choco/cocoa to another tobacco. Use the Chocolate if you also want to add a bit of sweetness and use the Cocoa if you also want to lower the sweetness of a tobacco. Once when I was out of Casablanca I also added FSUSA Vanilla Tahity or FSUSA oRYental 4 (caramelly and sweet tobacco) to Desert Ship carts or cartos to make it more complex and change up the flavor. Sometimes when I have Casablanca I add more Cocoa when I want a stronger vape. Those juices I listed are excellent mixers.
BWB Peach is also good added to a plain tobacco to make Peach tobacco. Even my original Chinese PG "tobacco" eliquid was decent with peach added.
I also like BWB Vanilla Bean a lot. I started just using it as a mixer and it seduced me with its flavor.
I also like WOWBacco from Vapor4Life - a cocoa tobacco that seems mostly cocoa to me. it's a clear liquid. I love it. And sometimes I add more cocoa with FSUSA Cocoa.
I found Tasty Vapor Peach Melba interesting - not at all what I expected. I expected light fruity creamy but instead it is a dark flavor, barely sweet with sweetener requested (as recommended on the order page). I think the brandy must darken the taste. I liked it and though in an odd way it was similar to an RY4 tobacco, dark and complex and a bit sweet. Note - tasty Vapor will be adding samples for some of their juices May 1. I think not the melba though.
