Per their website:
For those of you who are curious, this new take on coffee is made through an innovative process. We start with high-quality, green coffee beans. We soak the beans in water and pull out the caffeine and other good stuff. Then we dry the whole concoction down to create the concentrated essence and goodness of green coffee. That's Green Coffee Extract. No roasting. None of the steps that coffee beans typically take on their way to roasty perfection. So the end result is a natural source of energy which has no traditional coffee flavor.It seems like Starbucks has done for coffee what green tea extract did for tea. Although I will always prefer my bold, dark, spicy, robust roasted coffee, I had an open enough mind to try the two flavours they are blending in the stores. So here are my takes:
Cool lime: Mildly sweet & sour, limeade flavour with a little kick of energy from green coffee. The former bartender in me wanted to add a little rum, tequila or vodka to this.
I'm glad to see Starbucks trying other angles besides traditional coffee beverages as well or teas. More variety is always a good thing! And FYI: these two flavours are available as instant Via™ for you to mix and shake in your water on your own. They also have Strawberry Lemonade, Raspberry pommegranate and an Orange Melon sparkling (carbonate) flavours sold in cans. Try them in your local Starbucks now!
Drink up Happily, y'all!
