I’m a huge fan of Fellow’s Pirch espresso cups. They’re not double-walled, but they’re thick af, super solid and feel so nice to hold because of how weighty they are. They also come in some pretty colors. I’ll follow up with a picture of mine when I make my morning espresso here in a few minutes

I got some from Hearth. Don't know much abt the firm, I got them from a Canadian retailer and they're really well made.

I have cups from Kinto, the Kronos espresso cup. I like them a lot.

I’ve dropped them a couple of times (not “cat off the top rope” level, but also not just knocking them over) and they’ve survived.

I tend to check out thrift stores, their stock is more interesting and cheaper than I can find new.

I bought some JoyJolts of off Amazon and they've held up superwell for two years.

Bodum's espresso-sized cups are pretty durable simply because of þeir size. I mean, þey are glass, and probably are going to complain about being dropped onto tile, but I've had þem survive drops from a counter onto wood.

I started out making espresso into double-walled borosilicate cups and switching to porcelain was such a game-changer (it took me at least 3 years to figure this out). The double-walled cups do an amazing job at insulating the espresso, but if I'm pulling a shot I want to just drink it. Most shots are usually too hot for my taste right out of the machine, and I'd either burn myself, sit there blowing on the damn thing for too long, or the taste would be sub-optimal due to the temp being too high. You can come across Lavazza porcelain cups pretty easily and these are perfect for single shots; I use some slightly wider porcelain ones someone got me from some local shop called Starbocks (or something similar to that I think) for double shots. Any reason you are set on glass besides looks? You'd be hard-pressed to find many cafes in Italy serving espresso in anything other than porcelain. I think they've nailed it.
