Sipdown. Prefer this to Matevana by a long shot as this is much smoother and the flavors are better integrated, though a tad flat. Brews up nice and dark. Hazelnut with a hint of chocolate. Benefits from the addition of almond milk.
By the way, if you’re looking for a mate-based coffee substitute, the best – by far – that I’ve found is Guayaki’s Javamate, in either Vanilla or Mocha Maca flavors. That is purely on a flavor and body basis… you can even brew it in your coffeemaker. And there are pluses, as well — it is a socially-responsible company and these products also contain ramon nut, a rainforest “superfood” that’s still largely under the radar, at least in the US. Whole Foods used to carry it but now you can only order it from the company, apparently.
