They did it! Suntory finally decided to export the Boss Rainbow Mountain Blend to the States!! This is perhaps one of the most requested Boss Coffee flavors. It's a double shot of espresso + milk and sugar and is made using beans certified from the Rainbow Mountain growing region in Guatemala. It's a smaller can but packs a punch with 110mg caffeine. Also flavor-wise, it's less sweet and creamy than the Boss Au Lait. 

6 fl oz Please refrigerate before enjoying

Gluten-free, soy-free, and vegetarian. 

PS. Do you want to know a secret? Boss Coffee cans are made of steel because, in Japan, you can buy them warm from vending machines. If you want to warm up your Boss, bring a pot of water to a boil, then take it off the heat and let your can take a bath until it's at your desired warmth. Be warned, the can could be hot on your lips so be very careful! Also, be double-warned, do not boil the can!
