I’m using these Double Espresso glasses for my 2.7 oz coffee pods. The glasses are 4.5, and so with the sugar, some flavoring, milk foam or whip cream, it comes to be the perfect size. I love how it has a handle, which at this size is big enough for most hands. The double glass is what is the best part on this. It’s never hot on the outside and stays hot longer. I’ve looked into other similar double walled glasses but the Zwilling one’s, in my opinion have the best shape. Easy dishwasher and never had an issue with breakage. Highly recommended!
