There are beautifully crafted and impeccably crafted Dopelwandgläser with the typical advantages: Good touching despite hot contents, keeping warm longer, etc. I have a Gastroback 42612 espresso machine: In any case, you have to measure accurately whether the glasses fit under it, they fit Gerdo so topsy ; However, it gets in any case closely under the machine, because these glasses on top due to their "pleasing shape" quite expansive are (diameter note). Conclusion: owner of more compact machines should pay attention to the dimensions. It works, but is narrow and "hakelig" under Espresso Machines. What is not: Milchaufschämen in glass. At the very least, these glasses have a rounding bottom, the milk is pressed inevitably on the opposite side back to the glass wall high and out. But frothing milk certainly does not belong to the primary intended use of such glasses.
