My three all day vapes:
Virgin Vapor's Organic Kona Velvet Milkshake. You just might try this one and forget about the rest of your juices. Very special and usually ends up being a favorite to anyone who tries it. Smooth, rich, mildly sweet, and complex flavor.
Copper Creek's Coffee. Fine dark roast, black. No burnt grounds taste like some inferior coffee vapes. I add some Sweet Cream e-juice from MyFreedomSmokes to make it taste creamy and mildly sweetened. The best simple coffee flavor I've found, and I've tried a few.
Copper Creek's House Blend. Not officially a coffee flavor, but such a fine quality juice with a coffee name. Another almost universally liked flavor, it won a popularity poll of all e-juices in 2011.
VapeRite's Organic Double Espresso OK, I know I said top 3, but since trying this recently I find myself reaching for this throughout the day and evening. This is a strong flavor with an excellent throat hit -- it IS a double shot after all. Authentic espresso flavor, just the slightest bitter like an espresso should be. I like this when I need a "wake-me-up" vape when I'm bored with my other flavors, or when I'm winding down before bed. If you like espresso and need a strong flavor, this might be the one.
