Glass and ceramic mates have become popular in recent time because they can help if you suffer from acid indigestion. The natural gourds can mix with yerba mate to give an acidic effect, so by using a glass/ceramic mate you will avoid this.
It has also become fashionable in Syria to drink yerba mate in these small glasses with a small bombilla, as individual servings.
The dimensions of this mate cup are:
Diameter at the widest point – 5cm
Height – 7.3cm
Volume – 100ml
