Love this stuff! I'm a person who prefers tea and had stopped drinking coffee years ago but had never tried Yerba Mate tea. After trying, I am a complete fan.It has caffeine as many teas do, but to me, it feels almost like an expresso boost of energy but without the jitters. I mean, I feel like I am much more alert and I have much more energy during my days when I drink this stuff.Did some research and found out that the yerba mate plant is a tree in South America that is known for its caffeine and is quite popular in several South American regions. Some countries drink it plain while others drink it with adding sweeteners and/or citrus juices. I've been experimenting and trying many different ways to find out which method I I prefer best but I can drink it plain or sometimes I do add a sweetener, it just depends on how I feel.Some people say it's best not to boil the water completely while others say it should be at a certain temperature. So I will suggest trying this with many different water temperatures to find out what suits you best.It could be me, but it seems like after steeping in hot water that the water cools down quite quickly which seems different from other hot beverages. Just my observation. I actually like that I don't have to wait long to really drink down the concoction because the water seems to cool so quickly after I've steeped my bag. Another thing, I've noticed is that while the water turns kind of a golden brown, it seems to get darker as time progresses to like a dark green.The tea itself has many different tastes that is hard for me to describe. It has an earthy woodsy taste and smell that can be mild or bitter depending on the various methods you prepare it and how hot or cool the water is when you steep it.In my research, I found that it may provide some much needed weight loss especially in the belly area if that is a factor for you. But that is my research and not what this product is claiming. I just know I like the way it makes me feel and the subtle boots of energy that it gives me after drinking it which lasts throughout the day.I would definitely recommend trying this, especially if you don't have any caffeine aversions.
