The Stirr'accino is poured into four separated layers that you can "stir" together before drinking.
The bottom layer is brewed coffee made from a blend of light roast Arabica beans with what appears to be a layer of steamed milk next, then a layer of espresso, and finally, a top layer of milk foam.
The overall visual effect is pretty interesting, but probably wouldn't work so well here in the States where most coffee is purchased to-go.
