Man, I got my first espresso machine (Breville Barista Express) a few days ago and your videos have been such a helpful tool in learning so much as a beginner. Keep up the epic work!

I think the initial difference of temperature between the two is a larger effect than what you state: I’m looking for glassware that will minimize total immediate heat drop, not just keep it warm for longer, as I’m not a slow drinker. Dual walls are definitely the big winner based on your graphs.

I got dual wall cups last summer for cold drinks, and I noticed the ice wouldn’t melt for noticeably longer. I didn’t count but It’s say it lasted at least twice as long. They are more comfortable to use and the body heat doesn’t melt the ice. Maybe they don’t perform as well for hot drinks, but I became a fan of dial wall glasses since then.

I use a stainless steel insulated cup for my morning coffee to work. Coffee stays HOT for hours. For around the house i like my double wall glass mugs. They absolutely keep coffee warmer, longer than a traditional mug. If it does get cold, being glass, you can just pop it into the microwave. Also works good keeping cold drinks cold. Doesn't sweat like a traditional glass.

Have you ever tried those phase changing Coffee Joulies before? I love my ember mug and after using a dual walled espresso cup for like a week, I really didn't like that initially held its temp, and really prefered the initial faster cool down of a ceramic cup so that it is more in the drinkable range faster (instead of just having to stir it a bunch and wait a few mins for it to be drinkable)! I also used to have phase changing metal spheres from Coffee Joulies for my automatic pour over machine that quickly brought the temp down to a drinkable 140 degrees, and thenmaintained that temp for a decent amount of time. I kept them in the carafe to give me more time to drink the larger portion! If you have tried them hat are your thoughts on Joulies?

Another thing to consider too is the size mug you are using. Here, he compared similar volume capacity mugs. I've often seen people pouring their 10 oz coffee into a 16 oz mug or some similar situation, and that will definitely affect cooling rate.

Did you do the test with foamed milk on top? You’d have thought the foamy milk would act as an insulating cover. (Air after all is the best insulator) As in my day to day experience they definitely keep flat whites/lattes/cappuccinos etc hotter. Maybe it’s the smaller opening on my current ones, but I’m getting a Kruve imagine (because of how good the cheap ones have been) so I’ll soon know if it works less well at keeping my flat whites hotter. With americanos or filter coffee I wouldn’t bother with dual walled glasses.

I don't think keeping a drink warmer for longer is a common use-case people have for these glasses. But yes, valid point. Also what I don't like is that you have to wash them by hand, in a dishwasher they can get messed up quite easily

The Ember mug has been one of my favorite purchases ever I found it far superior to dual wall mugs I sip my coffee over like an hour or so and having it warm still is great. Plus drinking coffee at that perfect temperature all the time greatly improved the flavor The dual wall with lid I also hate because it keeps it in the hot temperature zone for too long and by the time I remember to check it’s room temp

So, do any espresso 2 to 3.5 ounce double walled containers with a sipping lid?

Hi, i am brazilian and your content is very good ! My set up is Breville infuser with Breville grinder , in my country is very dificult access many brands . But What dou you think to upgrade grinder like a Baratza sette 270 for espresso , cause i think Breville in fines ajustment suffer to bring a good consistency. What your opnian to upgrade a espresso machine in future. Thanks a lot.

I bought a 4 pack of dual walls, but that's because they're really convenient to pour the espresso in with the milk and chocolate in my breville milk frother. And they look great. Temperature in my beverages mostly comes from the milk 😅

Where can you get insulated lids?

For years,I have been using a dual wall stainless steel mug with a lid to keep my 12 oz coffee hot. I am a slow drinker. I preheat the mug and it keeps my drinks hot for a very long time. It is much, much cheaper than a ember mug and works great!

Apples to oranges comparison. First review I think you have missed the mark. Double walled glasses are intended to provide hand comfort from heat, cold & condensation. They also provide a practical way to check crema for depth and texture, and an overall aesthetic view of espresso shot or cappuccino layering. Double walled glass does these things very well and at a good price point ($8)@). They are not intended to hold the drink temperature for an extended period of time as I understand the Ember does very well.

I tried them and don't like then either, they delay the cool down for espresso, it could be argued that increases evaporation of volatiles before you can drink your espresso. I'd almost go the other way and chill the cup if it wasn't such an inconvenience.

I use dual wall mug for espresso only. They taste so good and have such a small volume that they are finished way before they have a chance to cool. A vacuum filled chamber dual wall mug would keep coffee warm a long time, but obviously couldn't be made of blown glass.

It could just be a temperature thing since flavour perception is temperature dependent and a 6-degree different is quite significant. The "contamination" could just be the additional flavour that you can perceive at a lower temperature.

Dual wall is just flawed concept prone to breaking or puncture and forget the surface area is the biggest cause of temperature loss

For everyday drinkin', I like the Avensi dual-walled glasses. They look great, are fairly thick gauge (I find the Kruve glasses really thin and fragile), feature a single-wall thin lip for pleasant drinking, and are designed on purpose to cool a drink to a drinkable temp with swirling (a high side wall increases the surface area with a swirl). Perfect for a morning cuppa. To keep coffee hot for a long time, I like a Fellow Carter Move. Also dual walled, feature a thin lip for pleasant drinking, fit in a car cup holder, and keep coffee really hot for something like 12h. These will hold more liquid than an Ember, are sealed and can be thrown in a bag (great for road trips and work travel), and use no power. At least for me, an Ember falls in this middle area where its advantages are done a little better by other drinkware. To each their own though, thanks for the vid!
