I picked this drink up at HMart along with Nongshim Shin Spicy Cup Noodles and Ottogi Yeul Ramen, among other things. I was hoping to find BOSS coffee in the can but no such luck existed that day. In any case this was something I hadn't seen before so I figured it could be interesting to try.

Craft Boss Sunny Coffee Lemon (クラフトボス・サニーコーヒー・レモン) is a drink from Suntory made with coffee and at least 9% lemon and apple juice. It comes in a plastic bottle and is refreshingly sweet (すっきり甘い). We'll see about that.

First sip: what the fuck. The sour taste of lemon juice slaps me in the face. I can't discern much beyond the sourness. It actually has citric acid listed as an ingredient beyond lemon juice and apple juice. It's like they are acid-adjusting a glass of lemonade cut with apple juice. Incredible.

Overwhelmingly its taste is redolent to me of Brisk iced tea with further bitter notes stemming from the addition of coffee.

Through the lemon overtones I can still taste the distinctive BOSS coffee hiding in this drink. The actual caffeine content is a mystery and I'm not sensitive enough to caffeine right now to guess it either.

This user limits caffeine consumption

I can't imagine this would be refreshing on a hot day as it's so sour and has a fair amount of sugar (54g) for one 500ml bottle, 220cal.
