Glass is a great alternative material to our porcelain cups. It is a green, 100% recyclable, strong and non porous material. However, we found there are very few choices of glasses for baristas to choose from.
It has a thickness of 5mm, which retains heat extremely well. It has an interesting twisted exterior that refract light differently, with a curved interior that has the same feature as our porcelain cups. The continuous curve lets the crema develop fully and gives an amazing mouth feel.
