The stevia flavors here aren't as forward as they are in the other High Brew drinks, but using stevia is probably the only way it can manufacture a caramel drink with just 8g of sugar. The more you drink, the more artificial both the caramel and the stevia taste, despite the drink using "natural flavors!" As with all of the High Brew drinks, the stevia and the flavoring outshine the coffee.
I love dirty chais (chai with espresso), but this tastes like chai with no coffee. On the upside, the chai is delicious. It tastes like an iced almond milk chai you'd pay $5 for at a coffee shop, and considering buying this means you won't have to wait five minutes for someone to make it, or tip, buying this isn't a horrible value proposition.
The good news: there's only 8g of sugar for a super-strong mouthful of mocha flavors that don't taste fake! The bad news: a rush of stevia comes in at the end and ruins everything. Some people don't mind stevia! It tastes close enough to sugar for them. I am not one of those people. To me, stevia ruins drinks like an ex barging in at a wedding when the preacher asks if anyone opposes this union. Why you gotta ruin the ceremony, stevia?!
