Shout-out to Yerba Mate tea (which this drink is based on) which I got introduced to on a recent trip to Argentina and now enjoy at home now and then, thanks to Amazon (I got the special cup and special metal filter straw and everything!). It's been called a "supertea" due to its various health benefits in addition to being a CNS stimulant. I'd recommend trying it. I add a little honey, but sweetener is up to you.

For reference I got this mate mug https://smile.amazon.com/gp/product/B01GJXBR94/ref=oh_aui_se... and these straws ("bombillas") https://smile.amazon.com/gp/product/B01M1N9U23/ref=oh_aui_se... (because the one that came with the mug let a bit too much tea particulate through) and am very happy with that combo.

Here's a good video on the "ritual" of making it: https://www.youtube.com/watch?v=-BW1-pE4XaE
