This concentrate was provided to me free of charge for review purposes by the good people at Chefs Vapour Chefsvapour Mixed this up with a simple 60/40 VG/PG mix, and the nicotine level was set at 12mg. Concentrate was added at 15% level. Used the good old milk frother to steep the hell out of it, I then put it away for a week in a cool dark place. Filled up a Protank Mini 3 and vaped away - I'm very impressed! The flavour you get is a very authentic coffee flavour, with just a subtle hint of the cinnamon. I was worried it would be too sweet and the cinnamon would take over, but this isn't the case at all. It's not as strong as other coffee flavours I've vaped (Caramel Cappuccino, Lews Brew, Emp Vaps Coffee & Rum), and I think when I mix up the next batch I will increase the % to 18, maybe even 20%. Highly recommended, and can be purchased from the Chefs Vapour website.
