I only ever drink black coffee so don’t really know much about fancy ones but if you click on the link below it will take you to tassimo website- click on the pod your using/looking for and scroll down the bottom of the page you’ll see a nutritional info tab for that particular drink - I noticed a caramel latte is nearly 11g of carbs all of it sugars
I've had a Tassimo for a few years and the only one I think that doesn't contain sugar is the Americano which I have black topped up with a little cold water as it comes out pretty hot , I think it tastes good so not a problem for me !
