Chocolate and Cocoa are vastly different. I use Choc or choc+cocoa only as a liqueur flavor in complex recipes. It tastes like an alcoholic beverage to me, and works well as one if the recipe is just right. Standalone Chocolate? No way, not for me. Cocoa is perfectly named; you'll see when you try it. With VT nic, it's excellent standalone or with a hint of b'scotch, caramel, marshmallow...something sweet/creamy. With WL nic, it takes a lot of additions (IMO) to taste sweet enough, and it's a balancing act to keep the superb cocoa flavor versus getting it sweet/creamy enough. The improvement in Cocoa alone is enough reason to get VT nic! My favorite recipes with Cocoa are my Basic Cocoa Cookies and Thin Mints. They're excellent chocolate flavors made with Cocoa and work with any nic base.
First off, thank you

Different is what I was looking for. I have a few other chocolate flavors I like, though I feel they need a little boost and I'm hoping the cocoa will provide it. I'm actually looking for a deeper cocoa taste, so if it's a little bitter, that's perfect!
Almond smells like almond extract made from sweet almonds. Marzipan is almond paste made into candy, so it's very sweet, but with the flavor of bitter almond. Bitter almond is the distinctive flavor in amaretto liqueur. I use it as a sweetener in recipes that need a bit of almond or liqueur flavor. Check out my Amaretto Disaronno recipe to see how Almond and Marzipan work together. I use almond exactly like I'd use almond extract. Sometimes you need both, for a balanced almond flavor. I don't like real marzipan (though I love amaretto), but it's great for vape recipes.
I may be on the fence with Almond. I was hoping it'd be more of a deep, nutty almond (like almond butter) instead of the extract, though I'm sure I'll find a use for it. Marzipan was picked up simply because of me picking up Almond. Despite not being the deeper, nutty flavor, I'm sure I'll find a use for them both.
Torrone is Italian nougat candy - google photos, bet you've had it. I sometimes use it as a sweetener in Italian-inspired recipes. Mostly, I use it as torrone! Great plain, or add one nut flavor and/or fruit for authentic Italian candy. (pistachio-cherry, walnut-mandarin, like that) I don't like real torrone, but even standalone, it's a favorite vape for me.
I've honestly never tried it. Most of the "authentic" candy around here is far from it. The closest thing to Torrone here would be divinity fudge, which is basically marshmallow cream, sugar, butter and pecans or almonds. It's like a "nougat" but so far from it at the same time. It's overly sweet and loaded with sugar and pricey for what it is. Unless I head towards Knoxville, Chattanooga or Nashville, we don't have too many candy shops here in East Tennessee - none that really do hand-made / crafted candies (I WISH!).
Except for Chocolate, the flavors you asked about are all perfectly accurate to their names. Cocoa, Torrone, and Marzipan in particular are 3 of FA's very best. No other brand comes close to similar flavors and, armed with an Italian dessert cookbook, you can make awesome vape recipes. In fact, you couldn't make accurate Italian dessert flavors without them (and espresso, and several others).
Espresso is one I missed, but it'll be in a follow up. Not sure how I missed it, but I did

. Thanks for the help HIC - definitely appreciated. Hopefully they'll be here this week and if they come out as good as you say, I'll be following up with some larger bottles!
