Mess with the best and die like the rest. In terms of canned and bottled coffee, Suntory's BOSS rules them all. Although this stance is largely personal bias it is firmly what I believe. It even says this on the side of the vending machines: Boss is the boss of them all. So don't doubt it for a second.

Craft Boss is the bottled brand from Suntory and is significantly more coffee, weighing in at 500ml, compared to the same company's canned Boss Coffee which is 185ml. Craft Boss is targeted towards office workers (the tagline under Craft Boss says Work & Peace) because the PET bottle can be resealed and enjoyed throughout the morning, unlike the typical steel can Boss Coffee which cannot be resealed and is meant to be enjoyed on-the-go.

Craft Boss Black is strong with a light bitter finish. Even with this bitter note it is surprisingly easy to drink. There's one word on my mind when I drink this: Smooth. Energizing too, obviously. It's just coffee and almost nothing else. Simple.
