This is my favorite of the Boss Coffee products. High quality, not too sweet, and genuinely well-sourced coffee blend. I am a regular consumer of this product and will continue to be. Japanese Taste delivered much more quickly than I anticipated, so they have made me a repeat customer.
- ASAri S.Verified BuyerReviewingSuntory Boss Rainbow Mountain Blend Coffee 185gI recommend this productRated 4 out of 5 stars9/11/26Really sweet for a coffee
This is the milk coffee with sugar version of Suntory's coffee drinks offering. I personally found it a bit too sweet, it's almost soda-like. Otherwise it's pretty decent. Heated it up in a hot water.
