“There was a lot of hype about the mug making the coffee taste better. I don't have know if it was in my head while giving it a good week long test but I've tried with lattes at my shop and folgers at my house. Sure enough my folgers tasted like unicorns all of a sudden. My latte tasted great as well but I really noticed a brightness with my boring drip. With that being said, I will test it with a fine pour over with crafted roasted grinds next. I love that I can toss it in my passenger seat when in a hurry too, the seal works great. A+ for the 12oz Carter Wide Travel Mug.”
