I now use this gourd more than my traditional gourd made from a real gourd!
The 5oz. size is perfect. I fill it halfway with mate, and can empty it in two or 3 sips. meaning that the flavor does not get overly strong unless I want to let the water sit longer. Cleaning is easy, which means I can use it all day. With a traditional gourd, once finished, you have to clean it out good and let it dry out. With this one, you can let it sit indefinitely, or clean it out, dry it out with a towel, and use it again immediately. With Rosemonte Especiale, filling it halfway will let me get about a liter and a half of water used before the flavor goes out. The inside shape is conical and does not follow the same contours as the outside, and the outside does not get warm when using. Also works pretty well for making tereré if you don't find the small size (5 oz.) a problem.
