Well firstly, energy drinks such as Red Bull (read as: “Red Bullshit” because it does not work) are not as popular in Asian culture as the coffee counterparts. Since Asians enjoy their coffee night and day, I have high expectations for these coffees in a can.
Dydo コーヒーBlend Coffee

This is a cold milk coffee originating from Japan that is rather dilute and sweet. It tasted less milky and more watery. After drinking this coffee, my body filled with stimulant but the pay off was a sickly stomach. While the taste is acceptable, the watery blend with milk is not good on the stomach. I would not recommend this drink over freshly made coffee. 2/5.
Cafécino Espresso & Milk Double Shot

This is a product of Taiwan and tastes far better than that Dydo junk. Less dilute and more sweet it's quite a nice light blend that has a more authentic taste of Asian milk coffee. Cafécino has emulated the taste well but still, nothing beats the original stuff. 3/5.
Cafécino Espresso Double Shot

This is one is by far the better tasting coffee of the latter. Made of coffee beans, water and sugar, I guess you cannot go wrong. The coffee was the non milk variant and tasted very similar to the ice coffee they serve in Vietnam. Albeit, for an espresso it is a little diluted, but I prefer my espressos that way instead of the hardcore shots. 3.5/5.
Needless to say, canned coffee is crap (read as: inferior) compared to the fresh roasted and blended alternative. The Cafécino Espresso Double Shot was a bare pass, but still does not compare to what any of us can make at home. I suggest you stay away from canned coffee unless you intend to review it.
However, If you are so inclined to try these, canned coffe is available at most Asian Groceries.
