It's a variant of Nescafé Blend & Brew.
For Silky Roast, ground coffee is brewed in liquid creamer. Then, Nescafé milk is added to the mix, [allegedly] resulting into a, well, silky coffee drink.
Is it really silky? Not really. Its consistency is the same with other instant coffee brands. As for the taste, it has an initial roasted coffee flavor, but this gets immediately drowned by sugary sweetness. Sayang!
Try it and judge for yourself.
